EXECUTIVE SUMMARY
Sexual violence, stalking, and
intimate partner violence are
major public health problems in
the United States. Many survivors
of these forms of violence can
experience physical injury, mental
health consequences such as
depression, anxiety, low self-
esteem, and suicide attempts,
and other health consequences
such as gastrointestinal disorders,
substance abuse, sexually trans-
mitted diseases, and gynecological
or pregnancy complications. These
consequences can lead to hospital-
ization, disability, or death.
Our understanding of these forms
of violence has grown substantially
over the years. However, timely,
ongoing, and comparable national
and state-level data are lacking.
Less is also known about how
these forms of violence impact
specific populations in the United
States or the extent to which rape,
stalking, or violence by a romantic
or sexual partner are experienced
in childhood and adolescence.
CDC’s National Center for Injury
Prevention and Control launched
the National Intimate Partner and
Sexual Violence Survey in 2010 with
the support of the National Institute
of Justice and the Department of
Defense to address these gaps.
The primary objectives of the
National Intimate Partner and
Sexual Violence Survey are to
describe:
• The prevalence and
characteristics of sexual
violence, stalking, and intimate
partner violence
• Who is most likely to experience
these forms of violence
• The patterns and impact of the
violence experienced by specific
perpetrators
• The health consequences of
these forms of violence
The National Intimate Partner
and Sexual Violence Survey is an
ongoing, nationally represen-
tative random digit dial (RDD)
telephone survey that collects
information about experiences
of sexual violence, stalking, and
intimate partner violence among
non-institutionalized English and/
or Spanish-speaking women and
men aged 18 or older in the United
States. NISVS provides detailed
information on the magnitude
and characteristics of these forms
of violence for the nation and for
individual states.
This report presents information
related to several types of violence
that have not previously been
measured in a national population-
based survey, including types
of sexual violence other than
rape; expressive psychological
aggression and coercive control,
and control of reproductive or
sexual health. This report also
provides the first ever simultaneous
national and state-level prevalence
estimates of violence for all states.
The findings presented in this
report are for 2010, the first year
of data collection, and are based
on complete interviews. Complete
interviews were obtained from
16,507 adults (9,086 women and
7,421 men). The relative standard
error (RSE), which is a measure
of an estimate’s reliability, was
calculated for all estimates in this
report. If the RSE was greater than
30%, the estimate was deemed
unreliable and is not reported.
Consideration was also given to
the case count. If the estimate
was based on a numerator ≤20,
the estimate is also not reported.
Estimates for certain types of
violence reported by subgroups of
men such as rape victimization by
racial/ethnic group are not shown
because the number of men in
these subgroups reporting rape
was too small to calculate a reliable
estimate. These tables are included
in the report so that the reader
can easily determine what was
assessed and where gaps remain.
Key Findings
Sexual Violence by Any
Perpetrator
• Nearly 1 in 5 women (18.3%) and
1 in 71 men (1.4%) in the United
States have been raped at some
time in their lives, including
completed forced penetration,
attempted forced penetration,
or alcohol/drug facilitated
completed penetration.
• More than half (51.1%) of female
victims of rape reported being
raped by an intimate partner
and 40.8% by an acquaintance;
for male victims, more than
half (52.4%) reported being
raped by an acquaintance
and 15.1% by a stranger.
• Approximately 1 in 21 men
(4.8%) reported that they were
made to penetrate someone else
during their lifetime; most men
who were made to penetrate
someone else reported that
the perpetrator was either an
intimate partner (44.8%) or an
acquaintance (44.7%).
• An estimated 13% of
women and 6% of men have
experienced sexual coercion
in their lifetime (i.e., unwanted
sexual penetration after being
pressured in a nonphysical
way); and 27.2% of women and
11.7% of men have experienced
unwanted sexual contact.
• Most female victims of
completed rape (79.6%)
experienced their first rape
before the age of 25; 42.2%
experienced their first completed
rape before the age of 18 years.
• More than one-quarter of male
victims of completed rape
(27.8%) experienced their first
rape when they were 10 years of
age or younger.
Stalking Victimization by Any
Perpetrator
• One in 6 women (16.2%) and 1
in 19 men (5.2%) in the United
States have experienced stalking
victimization at some point
during their lifetime in which
they felt very fearful or believed
that they or someone close to
them would be harmed or killed.
• Two-thirds (66.2%) of female
victims of stalking were stalked
by a current or former intimate
partner; men were primarily
stalked by an intimate partner
or an acquaintance, 41.4% and
40.0%, respectively.
• Repeatedly receiving unwanted
telephone calls, voice, or
text messages was the most
commonly experienced stalking
tactic for both female and male
victims of stalking (78.8% for
women and 75.9% for men).
• More than half of female victims
and more than one-third of male
victims of stalking indicated that
they were stalked before the
age of 25; about 1 in 5 female
victims and 1 in 14 male victims
experienced stalking between
the ages of 11 and 17.
Violence by an Intimate
Partner
• More than 1 in 3 women (35.6%)
and more than 1 in 4 men
(28.5%) in the United States
have experienced rape, physical
violence, and/or stalking by an
intimate partner in their lifetime.
• Among victims of intimate
partner violence, more than
1 in 3 women experienced
multiple forms of rape, stalking,
or physical violence; 92.1%
of male victims experienced
physical violence alone, and 6.3%
experienced physical violence
and stalking.
• Nearly 1 in 10 women in the
United States (9.4%) has been
raped by an intimate partner in
her lifetime, and an estimated
16.9% of women and 8.0% of
men have experienced sexual
violence other than rape by an
intimate partner at some point in
their lifetime.
• About 1 in 4 women (24.3%)
and 1 in 7 men (13.8%) have
experienced severe physical
violence by an intimate
partner (e.g., hit with a fist
or something hard, beaten,
slammed against something)
at some point in their lifetime.
• An estimated 10.7% of women
and 2.1% of men have been
stalked by an intimate partner
during their lifetime.
• Nearly half of all women and
men in the United States have
experienced psychological
aggression by an intimate
partner in their lifetime (48.4%
and 48.8%, respectively).
• Most female and male victims of
rape, physical violence, and/or
stalking by an intimate partner
(69% of female victims; 53% of
male victims) experienced some
form of intimate partner violence
for the first time before 25 years
of age.
Impact of Violence by an
Intimate Partner
• Nearly 3 in 10 women and 1
in 10 men in the United States
have experienced rape, physical
violence, and/or stalking by an
intimate partner and reported
at least one impact related to
experiencing these or other
forms of violent behavior in the
relationship (e.g., being fearful,
concerned for safety, post
traumatic stress disorder (PTSD)
symptoms, need for health care,
injury, contacting a crisis hotline,
need for housing services, need
for victim’s advocate services,
need for legal services, missed at
least one day of work or school).
Violence Experienced by Race/
Ethnicity
• Approximately 1 in 5 Black
(22.0%) and White (18.8%)
non-Hispanic women, and 1 in 7
Hispanic women (14.6%) in the
2 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 3
United States have experienced
rape at some point in their
lives. More than one-quarter of
women (26.9%) who identified
as American Indian or as Alaska
Native and 1 in 3 women (33.5%)
who identified as multiracial
non-Hispanic reported rape
victimization in their lifetime.
• One out of 59 White non-
Hispanic men (1.7%) has
experienced rape at some point
in his life. Nearly one-third of
multiracial non-Hispanic men
(31.6%) and over one-quarter of
Hispanic men (26.2%) reported
sexual violence other than rape
in their lifetimes.
• Approximately 1 in 3 multiracial
non-Hispanic women (30.6%)
and 1 in 4 American Indian or
Alaska Native women (22.7%)
reported being stalked during
their lifetimes. One in 5 Black
non-Hispanic women (19.6%),
1 in 6 White non-Hispanic women
(16.0%), and 1 in 7 Hispanic
women (15.2%) experienced
stalking in their lifetimes.
• Approximately 1 in 17 Black non-
Hispanic men (6.0%), and
1 in 20 White non-Hispanic men
(5.1%) and Hispanic men (5.1%)
in the United States experienced
stalking in their lifetime.
• Approximately 4 out of every 10
women of non-Hispanic Black or
American Indian or Alaska Native
race/ethnicity (43.7% and 46.0%,
respectively), and 1 in 2 multiracial
non-Hispanic women (53.8%)
have experienced rape, physical
violence, and/or stalking by an
intimate partner in their lifetime.
• Nearly half (45.3%) of American
Indian or Alaska Native men and
almost 4 out of every 10 Black
and multiracial men (38.6% and
39.3%, respectively) experienced
rape, physical violence and/or
stalking by an intimate partner
during their lifetime.
Number and Sex of
Perpetrators
• Across all types of violence, the
majority of both female and male
victims reported experiencing
violence from one perpetrator.
• Across all types of violence,
the majority of female victims
reported that their perpetrators
were male.
• Male rape victims and male
victims of non-contact
unwanted sexual experiences
reported predominantly male
perpetrators. Nearly half of
stalking victimizations against
males were also perpetrated
by males. Perpetrators of other
forms of violence against males
were mostly female.
Violence in the 12 Months
Prior to Taking the Survey
• One percent, or approximately
1.3 million women, reported
being raped by any perpetrator
in the 12 months prior to taking
the survey.
• Approximately 1 in 20 women
and men (5.6% and 5.3%,
respectively) experienced sexual
violence victimization other than
rape by any perpetrator in the
12 months prior to taking the
survey.
• About 4% of women and 1.3%
of men were stalked in the 12
months prior to taking the survey.
• An estimated 1 in 17 women
and 1 in 20 men (5.9% and 5.0%,
respectively) experienced rape,
physical violence, and/or stalking
by an intimate partner in the 12
months prior to taking the survey.
Health Consequences
• Men and women who
experienced rape or stalking
by any perpetrator or physical
violence by an intimate partner
in their lifetime were more likely
to report frequent headaches,
chronic pain, difficulty with
sleeping, activity limitations,
poor physical health and poor
mental health than men and
women who did not experience
these forms of violence.
Women who had experienced
these forms of violence were
also more likely to report
having asthma, irritable bowel
syndrome, and diabetes than
women who did not experience
these forms of violence.
State-Level Estimates
• Across all types of violence
examined in this report, state-
level estimates varied with
lifetime estimates for women
ranging from 11.4% to 29.2% for
rape; 28.9% to 58% for sexual
violence other than rape; and
25.3% to 49.1% for rape, physical
violence, and/or stalking by an
intimate partner.
• For men, lifetime estimates
ranged from 10.8% to 33.7% for
sexual violence other than rape;
and 17.4% to 41.2% for rape,
physical violence, and/or stalking
by an intimate partner.
Implications for
Prevention
The findings in this report under-
score the heavy toll that sexual
violence, stalking, and intimate
partner violence places on women,
men, and children in the United
States. Violence often begins at
an early age and commonly leads
to negative health consequences
across the lifespan. Collective action
is needed to implement prevention
approaches, ensure appropriate
responses, and support these efforts
based on strong data and research.
Prevention efforts should start early
by promoting healthy, respectful
relationships in families by fostering
healthy parent-child relation-
ships and developing positive
family dynamics and emotionally
supportive environments. These
environments provide a strong foun-
dation for children, help them to
adopt positive interactions based on
respect and trust, and foster effective
and non-violent communication
and conflict resolution in their peer
and dating relationships. It is equally
important to continue addressing
the beliefs, attitudes and messages
that are deeply embedded in our
social structures and that create
a climate that condones sexual
violence, stalking, and intimate
partner violence. For example,
this can be done through norms
change, changing policies and
enforcing existing policies against
violence, and promoting bystander
approaches to prevent violence
before it happens.
In addition to prevention efforts,
survivors of sexual violence, stalking,
and intimate partner violence need
coordinated services to ensure
healing and prevent recurrence
of victimization. The healthcare
system’s response must be strength-
ened and better coordinated for
both sexual violence and intimate
partner violence survivors to help
navigate the health care system
and access needed services and
resources in the short and long term.
One way to strengthen the response
to survivors is through increased
training of healthcare professionals.
It is also critically important to
ensure that legal, housing, mental
health, and other services and
resources are available and acces-
sible to survivors.
An important part of any response
to sexual violence, stalking, and
intimate partner violence is to hold
perpetrators accountable. Survivors
may be reluctant to disclose their
victimization for a variety of reasons
including shame, embarrassment,
fear of retribution from perpetrators,
or a belief that they may not receive
support from law enforcement.
Laws may also not be enforced
adequately or consistently and
perpetrators may become more
dangerous after their victims report
these crimes. It is important to
enhance training efforts within the
criminal justice system to better
engage and support survivors and
thus hold perpetrators accountable
for their crimes.
Implementing strong data systems
for the monitoring and evaluation
of sexual violence, stalking, and
intimate partner violence is critical
to understand trends in these
problems, to provide information
on which to base development
and evaluation of prevention and
intervention programs, and to
monitor and measure the effective-
ness of these efforts. Establishing
cost-efficient and timely surveillance
systems for all states, by using
consistent definitions and uniform
survey methods, will assist states
by providing policymakers much
needed information for enhancing
prevention efforts at the state level.
Ongoing data collection and moni-
toring of these problems through
NISVS and other data sources at
the local, state, and national level
must lead to further research to
develop and evaluate strategies
to effectively prevent first-time
perpetration of sexual violence,
stalking, and intimate partner
violence. This research should focus
on key gaps to address the social
and economic conditions (e.g.,
poverty, sexism, and other forms of
discrimination and social exclusion)
that increase risk for perpetration
and victimization. This work should
be complemented with efforts to
monitor strategies being used by
the field, to identify and rigorously
evaluate these approaches and
document their value. As effective
strategies are identified, research
examining how to best disseminate,
implement, and adapt evidence-
based prevention strategies, will
become increasingly important.
Much progress has been made in
the prevention of violence. There
is strong reason to believe that the
application of effective strategies
combined with the capacity to
implement them will make a differ-
ence. The lessons already learned
during public health’s short experi-
ence with violence prevention are
consistent with those from public
health’s much longer experience
with the prevention of infectious and
chronic diseases. Sexual violence,
stalking, and intimate partner
violence can be prevented with
data-driven, collaborative action.

1: Background and Methods
More than two decades of research
has shown that sexual violence
and intimate partner violence are
major public health problems with
serious long-term physical and
mental health consequences, as
well as significant social and public
health costs (e.g., Breiding, Black,
& Ryan, 2008; Logan & Cole, 2007;
Randall, 1990). Elevated health risks
have been observed in relation to
multiple body systems, including
the nervous, cardiovascular, gastro-
intestinal, genitourinary, repro-
ductive, musculoskeletal, immune
and endocrine systems (Basile &
Smith, 2011; Black, 2011). While less
is known about the health impact
of stalking, within the past decade
stalking has been increasingly
recognized as a significant public
health issue. The few studies that
have been conducted suggest that
those who are stalked are more
likely to report similar negative
mental and physical health
consequences (Davis, Coker, &
Sanderson, 2002).
In addition to the negative physical
and mental health effects of sexual
violence, intimate partner violence,
and stalking, prior research has
shown that experiencing these
forms of violence during childhood
and adolescence increases the
likelihood of experiencing these
forms of violence as an adult (Tjaden
& Thoennes, 2000; Smith, White,
& Holland, 2003). Consequently,
understanding sexual violence,
intimate partner violence, and
stalking experienced during
childhood and adolescence is partic-
ularly important in order to prevent
the reoccurrence of these forms of
violence across the life course.
CDC’s National Center for Injury
Prevention and Control launched
the National Intimate Partner and
Sexual Violence Survey (NISVS) in
2010. The survey was developed
and fielded with the support of the
National Institute of Justice, and
the Department of Defense.1 The
primary objectives of the National
Intimate Partner and Sexual
Violence Survey are to describe:
• The prevalence and characteristics
of sexual violence, stalking, and
intimate partner violence
• Who is most likely to experience
these forms of violence
• The patterns and impact of the
violence experienced by specific
perpetrators
• The health consequences of
these forms of violence
Data from the National Intimate
Partner and Sexual Violence
Survey can be used for a number
of purposes. First, these data can
help inform policies and programs
that are aimed at preventing sexual
violence, stalking, and intimate
partner violence. In addition, these
data can be used to establish
priorities for preventing these
forms of violence at the national,
state, and local levels. Finally, data
collected in future years from the
survey can be used to examine
trends in sexual violence, stalking,
and intimate partner violence and
to evaluate and track the effec-
tiveness of prevention efforts.
What is the National
Intimate Partner
and Sexual Violence
Survey?
The National Intimate Partner
and Sexual Violence Survey is
an ongoing, nationally repre-
sentative survey that assesses
experiences of sexual violence,
stalking, and intimate partner
violence among adult women and
men in the United States and for
each individual state. It measures
lifetime victimization for these
types of violence as well as victim-
ization in the 12 months prior to
taking the survey. The survey is
focused exclusively on violence
and collects information about:
• Sexual violence by any
perpetrator, including
information related to rape, being
made to penetrate someone
else, sexual coercion, unwanted
sexual contact, and non-contact
unwanted sexual experiences
• Stalking, including the use of
newer technologies such as text
messages, emails, monitoring
devices (e.g., cameras and GPS,
or global positioning system
devices), by perpetrators known
and unknown to the victim
1In addition to providing guidance in the development of the National Intimate Partner and Sexual Violence Survey, the National Institute of
Justice and the Department of Defense contributed financial support for the administration of the survey in 2010. The National Institute of Justice’s
financial support enabled the addition of a separate targeted sample of persons of American Indian or Alaska Native ethnicity. The Department
of Defense’s financial support enabled the addition of a separate random sample of female active duty military and female spouses of active duty
military. Data from these two additional samples are not presented in this initial report but will be described in future publications.
Additional Features that Distinguish NISVS
from Other National Surveys:
• Interviewers ask a series of health-related questions at the outset of the survey to establish
rapport and establish a health context for the survey.
• A graduated informed consent procedure is used to maximize respondent safety, to build
rapport, and to provide participants the opportunity to make an informed decision about
whether participation in the survey would be in their best interest.
• Interviewers establish a safety plan so that a respondent knows what to do if they need to
discontinue the interview for safety reasons.
• Interviewers follow established distress protocols, including frequent check-ins with the
participant during the interview, to assess their emotional state and determine whether
the interview should proceed.
• The survey includes detailed behavior-specic questions on components of sexual violence
and intimate partner violence that previous population-based national surveys have not
measured. Examples include information on types of sexual violence other than rape,
coercive control, and control of reproductive or sexual health.
• The survey is designed to assess violence in a way that is consistent across states.
8 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
• Physical violence by an intimate
partner
• Psychological aggression by
an intimate partner, including
information on expressive forms
of aggression and coercive control
• Control of reproductive or sexual
health by an intimate partner
In addition to collecting lifetime
and 12 month prevalence data
on sexual violence, stalking, and
intimate partner violence, the
survey collects information on the
age at the time of the first victim-
ization, demographic character-
istics of respondents, demographic
characteristics of perpetrators (age,
sex, race/ethnicity) and detailed
information about the patterns
and impact of the violence by
specific perpetrators. For example,
the National Intimate Partner and
Sexual Violence Survey:
• Links each individual act
of violence with a specific
perpetrator, enabling the
collection of all forms of
violence committed by a specific
perpetrator and allowing for an
examination of how different
forms of violence co-occur.
• Examines the length of time and
frequency of the occurrence of
sexual violence, stalking, and
intimate partner violence relative
to specific perpetrators
• Collects information on a range
of negative impacts (e.g., injury,
absence from school or work,
need for medical care) resulting
from experiences of violence by
individual perpetrators
• Gathers information from
respondents on a range of long-
term physical and mental health
outcomes that may be associated
with the experience of violence
There are a number of additional
features of the National Intimate
Partner and Sexual Violence Survey
that distinguish it from other national
surveys (see box), such as the
National Violence Against Women
Survey (Tjaden & Thoennes, 2000),
a one-time survey that the National
Institute of Justice and the Centers
for Disease Control and Prevention
conducted in 1995-1996; the National
Crime Victimization Survey that the
U.S. Census Bureau has conducted
annually for the Bureau of Justice
Statistics since 1973; and the state-
based modules on intimate partner
violence and sexual violence that 34
states/territories collected for at least
one year from 2005 to 2007 using
the Centers for Disease Control and
Prevention’s Behavioral Risk Factor
Surveillance System.
In sum, the National Intimate
Partner and Sexual Violence Survey
allows for an improved under-
standing of the public health
burden of sexual violence, stalking,
and intimate partner violence
nationally and at the state level.
Beyond estimating the prevalence
of sexual violence, stalking, and
intimate partner violence, the
survey captures information on
these forms of violence in ways
that maximize the ability to take
action to prevent these public
health problems.
How Was the Survey
Developed?
The development of the National
Intimate Partner and Sexual
Violence Survey was informed
by the National Violence Against
Women Survey, which provided
a starting point for the devel-
opment of the survey instrument; a
federally sponsored workshop that
focused on building data systems
The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 9
for monitoring and responding
to sexual violence, stalking, and
intimate partner violence (CDC,
2000); and a pilot methods study
that was conducted in 2007. The
pilot study was designed to help
address information gaps and
inform the development of a
national intimate partner, sexual
violence, and stalking surveil-
lance system. In 2007, the CDC
also convened an expert panel to
discuss findings from the 2007 pilot
study and to make recommenda-
tions on the design of the NISVS
survey instrument (Appendix A). The
panel consisted of practitioners and
advocates, subject matter experts
with experience in designing
measures of violence, and represen-
tatives from other federal agencies
with subject matter expertise
in sexual violence, stalking, and
intimate partner violence.
What Does This Report
Include?
This report summarizes findings
from the 2010 National Intimate
Partner and Sexual Violence Survey
data collection. The first three
sections present lifetime and 12
month prevalence estimates and
other descriptive information (e.g.,
the number of perpetrators, the
type of perpetrator, and age when
the violence was first experienced)
for the three primary types of
violence examined in the survey
– sexual violence, stalking, and
violence by an intimate partner.
The prevalence of these types of
violence by state of residence is
also presented. This report also
includes information on the impact
of intimate partner violence and
on the relationship between
violence and various health conse-
quences such as asthma, diabetes,
chronic pain, disability, and poor
mental health.
Methods
The National Intimate Partner and
Sexual Violence Survey is a national
random digit dial (RDD) telephone
survey of the non-institutionalized
English and/or Spanish-speaking
U.S. population aged 18 or older.
NISVS uses a dual-frame sampling
strategy that includes both
landline and cell phones. The
survey was conducted in 50 states
and the District of Columbia and
was administered from January
22, 2010 through December 31,
2010. In 2010, a total of 18,049
interviews were conducted (9,970
women and 8,079 men) in the U.S.
general population. This includes
16,507 completed and 1,542
partially completed interviews. A
total of 9,086 females and 7,421
males completed the survey.
Approximately 45.2% of inter-
views were conducted by landline
telephone and 54.8% of interviews
were conducted using a respon-
dent’s cell phone.
The overall weighted response
rate for the 2010 National Intimate
Partner and Sexual Violence Survey
ranged from 27.5% to 33.6%. This
range reflects differences in how
the proportion of the unknowns
that are eligible is estimated.
The weighted cooperation rate
was 81.3%. A primary difference
between response and cooperation
rates is that telephone numbers
where contact has not been made
are still part of the denominator
in calculating a response rate.
The cooperation rate reflects
the proportion who agreed to
participate in the interview among
those who were contacted and
determined to be eligible. The
cooperation rate obtained for
the 2010 NISVS data collection
suggests that, once contact was
made and eligibility determined,
the majority of respondents
chose to participate in the inter-
view. Additional information
about the sampling strategy,
weighting procedures, response
and cooperation rates, and other
methodological details of NISVS
can be found in the technical note
in Appendix B.
Survey Instrument
Violence Domains Assessed
The questionnaire includes
behavior-specific questions that
assess sexual violence, stalking,
and intimate partner violence
over the lifetime and during the
12 months prior to the interview.
Intimate partner violence-related
questions assess psychological
aggression, including expressive
aggression (5 items) and coercive
control (12 items); control of repro-
ductive or sexual health (2 items);
physical violence (11 items); sexual
violence (21 items); and stalking
(7 items). A list of the victimization
questions used in the survey can
be found in Appendix C.
Psychological aggression, including
expressive aggression and coercive
control, is an important component
of intimate partner violence.
Although research suggests
that psychological aggression
may be even more harmful than
physical violence by an intimate
partner (Follingstad, Rutledge,
Berg, Hause, & Polek, 1990), there
is little agreement about how to
determine when psychologically
aggressive behavior becomes
abusive and can be classified as
intimate partner violence. Because
of the lack of consensus in the
field at the time of this report,
the prevalence of psychologically
aggressive behaviors is reported,
but is not included in the overall
prevalence estimates of intimate
partner violence. Expressive
psychological aggression includes
acting dangerous, name calling,
insults and humiliation. Coercive
control includes behaviors that are
intended to monitor and control
an intimate partner such as threats,
interference with family and friends,
and limiting access to money.
Physical violence includes a
wide range of behaviors from
slapping, pushing or shoving
to more severe behaviors such
as being beaten, burned, or
choked. In this report, severe
physical violence includes being
hurt by pulling hair, being hit
with something hard, being
kicked, being slammed against
something, attempts to hurt by
choking or suffocating, being
beaten, being burned on purpose
and having a partner use a knife
or gun against the victim. While
slapping, pushing and shoving
are not necessarily minor physical
violence, this report distinguishes
between these forms of violence
and the physical violence that is
generally categorized as severe.
Questions on sexual violence were
asked in relation to rape (completed
forced penetration, attempted
penetration, and alcohol or drug-
facilitated completed penetration),
being made to penetrate another
person, sexual coercion, unwanted
sexual contact, and non-contact
unwanted sexual experiences.
Stalking questions were aimed at
determining a pattern of unwanted
harassing or threatening tactics
used by a perpetrator and included
tactics related to unwanted
contacts, unwanted tracking
and following, intrusion, and
technology-assisted tactics.
Perpetrator Information
Respondents who reported
experiencing violence were subse-
quently asked to identify individual
perpetrators by initials, nick name
or in some other general way so
that each violent behavior reported
could be tied to a specific perpe-
trator. Respondents were asked
a series of questions about each
perpetrator including age, sex, and
race/ethnicity. In addition, for each
perpetrator reported, respondents
were asked their age and their rela-
tionship to the perpetrator, both
at the time violence first began
and at the last time violence was
experienced. Additional questions
were asked regarding perpetrators
of stalking and rape. These include
questions about the respondent’s
age when they first experienced
stalking by each perpetrator
and the age at which they last
experienced stalking. Separately,
questions were asked about the
respondent’s age when they first
experienced rape by each perpe-
trator and the age at which they last
experienced rape. Age and relation-
ship at the time the violence began
were used throughout this report.
Indicators of the Impact of
Violence Experienced
Follow-up questions related to
the potential impact of violence
committed by individual perpetra-
tors were asked. Respondents were
asked about whether or not they
experienced any of the following as
a result of any violence committed
by a specific perpetrator: fearful-
ness or being concerned about
safety, post-traumatic stress
disorder (PTSD) symptoms (e.g.
nightmares, feeling numb or
detached), injury, need for medical
care, need for housing services,
need for victim’s advocate or legal
services, having contacted a crisis
hotline, and missed days of work or
school. Respondents who reported
experiencing rape (completed
rape, attempted rape, or alcohol/
drug-facilitated completed rape), or
being made to sexually penetrate
another person were asked about
additional indicators of impact,
such as the contraction of a sexually
transmitted disease or pregnancy
as a result of the sexual violence.
Cognitive Testing
A key component of the question-
naire design process was
conducting cognitive tests on the
introductions and key questions
used throughout the instrument.
The purpose of the cognitive
testing was to provide information
on how well the questions worked
and whether participants under-
stood the text provided.
Survey Administration
Advance Letters
Reverse address matching was
used to link available addresses to
the landline sample. Approximately
50% of telephone numbers in the
landline sample were matched.
Prior to contacting participants,
informational letters addressed to
“Resident” were sent to available
addresses to make residents aware
that they would be receiving a
request for an interview in the
coming days. Following the World
Health Organization’s guidelines
10 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 11
for research on domestic violence,
introductory letters were carefully
written, providing only general
information about the survey to
maximize safety and confidentiality
(WHO, 2001).
Incentives
Respondents in the landline and
cell phone samples were offered
an incentive of $10 to participate
in the survey. Respondents could
choose to have the incentive
mailed to them or donated to the
United Way on their behalf; 58.4%
of respondents chose to donate
their incentive. For respondents
who chose to receive the incentive,
mailing information was obtained
so the incentive check could be sent
to them. Mailing information was
kept in a separate database from
data collected during the adminis-
tration of the survey and destroyed
at the end of data collection.
Graduated Informed Consent
Process
Following recommended guide-
lines (Sullivan & Cain, 2004; WHO,
2001) a graduated informed
consent protocol was used.
Specifically, to ensure respondent
safety and confidentiality, the
initial person who answered the
telephone was provided general
non-specific information about
the survey topic. The specific
topics of the survey (e.g., physical
aggression, harassing behaviors,
and unwanted sexual activity) were
only revealed to the individual
respondent selected. After a single
adult respondent in a household
was randomly selected to partic-
ipate, the interviewer administered
an IRB-approved informed consent
that provided information on the
voluntary and confidential nature of
the survey, the benefits and risks of
participation, the survey topic, and
telephone numbers to speak with
staff from the Centers for Disease
Control and Prevention or project
staff from the Research Triangle
Institute, International (RTI) (which
was contracted by the Centers for
Disease Control and Prevention to
administer the survey).
Respondent Safety and
Confidentiality
For topics such as intimate partner
violence and other forms of
violence and abuse, a graduated
consent process is often the safest
and most appropriate method
of research. Literature about the
ethical and safe collection of
research data on intimate partner
violence offers many reasons for
obtaining informed consent in a
graduated manner (Sullivan & Cain,
2004; WHO, 2001). In addition to
revealing the specific content of
the survey only to the respondent
selected, a graduated consent
process allows the interviewer to
build rapport and increases the
likelihood of gaining the partici-
pant’s trust, the key to minimizing
non-participation and under-
reporting. Carefully conducted
studies with well-trained inter-
viewers who are able to build
rapport and trust with potential
participants are essential both to
the collection of valid data and the
well-being of respondents.
Interviewers also reminded
respondents that they could skip
any question and could stop the
interview at any time. Interviewers
also established a safety plan with
the respondents so that respon-
dents would know what to do if
they needed to stop an interview
for safety reasons. Specifically,
interviewers suggested that
respondents answer questions in a
private setting and instructed them
to just say “Goodbye” if at any time
they felt physically or emotionally
unsafe. Interviewers also checked
in with the respondents several
times during the interview to make
sure they wanted to proceed. At the
end of the interview, respondents
were provided telephone numbers
for the National Domestic Violence
Hotline and the Rape, Abuse and
Incest National Network.
Length of Interview
The median length of the interview
was 24.7 minutes.
Interviewer
Recruitment, Training,
and Monitoring
Hiring, training and maintaining
high quality interviewers is
essential to maximize disclosure
of sensitive information about
sexual violence, stalking, and
intimate partner violence. Only
female interviewers administered
the survey as previous research
suggests that female interviewers
may be more likely to create
conditions conducive to disclosure
(Dailey & Claus, 2001). During the
hiring process, potential inter-
viewers were informed about the
background and purpose of the
National Intimate Partner and
Sexual Violence Survey and were
carefully screened to insure that
they were comfortable conducting
interviews on the topics included in
the survey. Interviewers received 16
hours of training and an additional
2 hours of post-training practice.
A detailed training manual written
specific to the National Intimate
Partner and Sexual Violence Survey
was developed. The content of the
Lifetime and 12 Month Prevalence Estimates of Violence
Lifetime prevalence refers to the proportion of people in a given population who have ever
experienced a particular form of violence. Lifetime prevalence estimates are important
because they provide information about the burden of violence within a population.
12 month prevalence provides information about the proportion of people in a given
population who have experienced a particular form of violence in the 12 months prior to
taking the survey. Twelve-month prevalence estimates provide a snapshot of the recent
burden of violence in a population. When collected over multiple years, 12 month estimates
can be used to assess trends in the burden of violence over time (suggesting whether
violence may be increasing or decreasing).
training manual focused on the
background information relevant
to the survey, project-specific
protocols, confidentiality proce-
dures, safety protocols, respondent
distress, and refusal avoidance.
The interviewer training sessions
were conducted using a variety
of methods, including lecture,
demonstration, round-robin
practice, paired-practice, and
group and paired mock interviews.
Interviewers were also briefed
on the potential challenges of
administering a survey on sexual
violence, stalking, and intimate
partner violence, and were trained
in administering questions about
these sensitive topics. Resource
information was provided to
interviewers regarding assistance
in coping with traumatic and
violent events. Interviewers were
also provided the opportunity to
discuss and process difficult or
upsetting interviews.
Project staff held bimonthly quality
assurance meetings with inter-
viewers during the data collection.
Throughout the data collection
period, approximately 10% of
interviews were monitored to
check the quality of their work and
to identify areas needing more
training or clarification. The infor-
mation obtained was then used
as a teaching tool for other inter-
viewers, when appropriate.
IRB and OMB Approval
The survey protocol received
approval by the Office of
Management and Budget
(OMB# 0920-0822) as well as
the Institutional Review Board
of Research Triangle Institute,
International.
Data Analysis
Lifetime and 12 month preva-
lence estimates were calculated
for the different forms of violence
presented in this report. The 12
month estimates were obtained
by asking respondents to report
whether the specific form of
violence by the perpetrator
occurred in the past 12 months.
Respondents were anchored to
the 12 month period with a CATI
reminder of the date (e.g., …in
the past twelve months, that is,
since {fill: date, 12 months ago}?”).
To be included in the prevalence
estimate for sexual violence,
physical violence, or psychological
aggression, the respondent must
have experienced at least one
behavior within the relevant
violence domain during the time
frame of reference (lifetime or
in the 12 months prior to taking
the survey). Respondents could
have experienced each type
of violence more than once so
prevalence estimates should be
interpreted as the percentage of
the population who experienced
each type of violence at least once.
To be included in the prevalence of
stalking, a respondent must have
experienced more than one of the
seven stalking tactics that were
measured in the National Intimate
Partner and Sexual Violence Survey,
or a single tactic multiple times by
the same perpetrator, and must
have been very fearful or believed
that they or someone close to them
would be harmed or killed as a
result of the perpetrator’s behavior.
Within categories of violence
(e.g., rape, other sexual violence,
any severe physical violence, any
reported IPV-related impact),
respondents who reported more
than one subcategory of violence
are included only once in the
summary estimate but are included
in each relevant subcategory. For
example, victims of completed
forced penetration and alcohol or
drug facilitated penetration are
included in each of these subtypes
of rape but counted only once in
the estimate of rape prevalence.
The denominators in prevalence
calculations include persons who
answered a question or responded
with don’t know or refused. Missing
data (cases where all questions for
constructing an outcome of interest
12 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 13
were not fully administered) were
excluded from analyses. All analyses
were conducted using SUDAAN™
statistical software for analyzing
data collected through complex
sample design.
The estimated number of victims
affected by a particular form of
violence is based on United States
population estimates from the
census projections by state, sex, age,
and race/ethnicity (www.census.
gov/popest/states/asrh/).
Statistical inference for preva-
lence and population estimates
were made based on weighted
analyses, where complex sample
design features such as stratified
sampling, weighting for unequal
sample selection probabilities, and
non-response adjustments were
taken into account. The estimates
presented in this report are based
on complete interviews. An
interview is defined as “complete”
if the respondent completed the
screening, demographic, general
health questions, and all questions
on all five sets of violence victim-
ization, as applicable. A comparison
of the demographic characteristics of
the complete interviews in the NISVS
sample and the U.S. population is
provided in Appendix B.
Analyses were conducted by sex.
Prevalence estimates by selected
demographic characteristics were
also calculated. No formal statistical
comparisons of the prevalence
estimates between demographic
subgroups were made. As
prevalence and population
estimates were based on a sample
population, there is a degree of
uncertainty associated with these
estimates. The smaller the sample
upon which an estimate is based,
the less precise the estimate
becomes and the more difficult
it is to distinguish the findings
from what could have occurred by
chance. The relative standard error
(RSE) is a measure of an estimate’s
reliability. The RSE was calculated
for all estimates in this report. If
the RSE was greater than 30%, the
estimate was deemed unreliable
and is not reported. Consideration
was also given to the case count.
If the estimate was based on a
numerator < 20, the estimate is
also not reported. Tables where
specific estimates are missing due
to high RSEs or small case counts
are presented in full with missing
unreliable estimates noted by an
asterisk so that the reader can
clearly see what was assessed
and where data gaps remain.
Tables showing the confidence
intervals around the estimates
are available at: www.cdc.gov/
violenceprevention/nisvs.
A number of health outcomes were
assessed in this survey and were
examined with respect to violence
victimization. Chi-square tests
were conducted to ascertain the
difference in the health outcomes
of interest with respect to victim-
ization. A p-value of .05 was set
as the threshold for establishing
statistical significance. Statistical
analyses for this report were
performed by Research Triangle
Institute, International and
independently replicated by statis-
ticians from the Centers for Disease
Control and Prevention.
Data Quality Assurance
An independent set of programs
were developed to ensure that skip
patterns, response values, missing
values, rotations, range checks,
and other logical consistency
checks had been implemented
as programmed in the computer-
assisted telephone interview (CATI)
system. The programs created a
number of quality control/quality
assurance variables and flags to
track such data as the frequencies
of behaviors with the frequencies
of the perpetrators, timeframes,
and other responses from each
perpetrator in order to compare
behaviors and/or their related
follow-up data. All discrepancies
were investigated and corrected as
appropriate. Additional informa-
tion on the data collection and
security procedures is included in
Appendix B.

2: Sexual Violence Victimization
Previous studies of sexual violence
victimization have shown that
it is a widespread problem that
happens early in the lifespan for
many victims, although sexual
violence can occur at any age
(Kilpatrick, Edmunds, & Seymour,
1992; Tjaden & Thoennes, 2000).
It has been more than a decade
since the sexual violence field
has had national prevalence
estimates of a wide range of
sexual violence victimization
experiences. To date, few national
studies have examined the various
forms of sexual violence (Basile
& Saltzman, 2002), particularly
types of sexual violence other
than rape. Previously, the only
nationally representative preva-
lence estimates measuring a wide
range of types of sexual violence
victimization were derived from
college populations (Fisher, Cullen,
& Turner, 2000; Koss, Gidycz, &
Wisniewski, 1987).
This section summarizes lifetime
and 12 month experiences of
sexual violence victimization of
women and men in the United
States, including rape (forced
penetration, attempted forced
penetration, and alcohol or drug
facilitated penetration), being
made to penetrate someone
else, sexual coercion, unwanted
sexual contact, and non-contact
unwanted sexual experiences.
What follows also includes lifetime
prevalence estimates by self-iden-
tified race/ethnicity, as well as the
characteristics of the victimization
experiences, including the type of
How NISVS Measured Sexual Violence
Five types of sexual violence were measured in NISVS. These include acts of rape (forced
penetration), and types of sexual violence other than rape.
• Rape is dened as any completed or attempted unwanted vaginal (for women), oral, or anal
penetration through the use of physical force (such as being pinned or held down, or by the
use of violence) or threats to physically harm and includes times when the victim was drunk,
high, drugged, or passed out and unable to consent. Rape is separated into three types,
completed forced penetration, attempted forced penetration, and completed alcohol or drug
facilitated penetration.
-Among women, rape includes vaginal, oral, or anal penetration by a male using his penis. It
also includes vaginal or anal penetration by a male or female using their ngers or an object.
-Among men, rape includes oral or anal penetration by a male using his penis. It also
includes anal penetration by a male or female using their ngers or an object.
• Being made to penetrate someone else includes times when the victim was made to,
or there was an attempt to make them, sexually penetrate someone without the victim’s
consent because the victim was physically forced (such as being pinned or held down, or by
the use of violence) or threatened with physical harm, or when the victim was drunk, high,
drugged, or passed out and unable to consent.
-Among women, this behavior reects a female being made to orally penetrate another
female’s vagina or anus.
-Among men, being made to penetrate someone else could have occurred in multiple ways:
being made to vaginally penetrate a female using one’s own penis; orally penetrating a
female’s vagina or anus; anally penetrating a male or female; or being made to receive oral
sex from a male or female. It also includes female perpetrators attempting to force male
victims to penetrate them, though it did not happen.
• Sexual coercion is dened as unwanted sexual penetration that occurs after a person is
pressured in a nonphysical way. In NISVS, sexual coercion refers to unwanted vaginal, oral,
or anal sex after being pressured in ways that included being worn down by someone who
repeatedly asked for sex or showed they were unhappy; feeling pressured by being lied to,
being told promises that were untrue, having someone threaten to end a relationship or
spread rumors; and sexual pressure due to someone using their inuence or authority.
• Unwanted sexual contact is dened as unwanted sexual experiences involving touch but not
sexual penetration, such as being kissed in a sexual way, or having sexual body parts fondled
or grabbed.
• Non-contact unwanted sexual experiences are those unwanted experiences that do not
involve any touching or penetration, including someone exposing their sexual body parts,
ashing, or masturbating in front of the victim, someone making a victim show his or her
body parts, someone making a victim look at or participate in sexual photos or movies, or
someone harassing the victim in a public place in a way that made the victim feel unsafe.
Nearly 1 in 5 women
and 1 in 71 men in
the U.S. have been
raped at some time
in their lives.

Prevalence of Sexual
Violence Victimization
Rape
Nearly 1 in 5 women in the United
States has been raped in her
lifetime (18.3%) (Table 2.1). This
translates to almost 22 million
women in the United States. The
most common form of rape victim-
ization experienced by women
was completed forced penetration,
experienced by 12.3% of women
in the United States. About 5%
of women (5.2%) experienced
attempted forced penetration,
and 8.0% experienced alcohol/
drug-facilitated completed forced
penetration. One percent, or
approximately 1.3 million women,
reported some type of rape victim-
ization in the 12 months prior to
taking the survey.
Approximately 1 in 71 men in the
United States (1.4%) reported having
been raped in his lifetime, which
translates to almost 1.6 million men
in the United States (Table 2.2). Too
few men reported rape in the 12
months prior to taking the survey to
produce a reliable 12 month preva-
lence estimate.

Sexual Violence Other
than Rape
Nearly 1 in 2 women (44.6%) and
1 in 5 men (22.2%) experienced
sexual violence victimization
other than rape at some point
in their lives (Tables 2.1 and 2.2).
This equates to more than 53
million women and more than 25
million men in the United States.
Approximately 1 in 20 women
(5.6%) and men (5.3%) experienced
sexual violence victimization other
than rape in the 12 months prior to
taking the survey.
Being Made to Penetrate
Someone Else
Approximately 1 in 21 men (4.8%)
reported having been made to
penetrate someone else in his
lifetime (Table 2.2). Too few women
reported being made to penetrate
someone else to produce a reliable
estimate (Table 2.1).
Sexual Coercion
About 1 in 8 women (13%) reported
experiencing sexual coercion in her
lifetime, which translates to more
than 15 million women in the United
States (Table 2.1). Sexual coercion
was reported by 2.0% of women in
the 12 months prior to taking the
survey. Six percent of men reported
sexual coercion in their lifetimes
(almost 7 million men), and 1.5% in
the 12 months prior to taking the
survey (Table 2.2).
Unwanted Sexual Contact
More than one-quarter of women
(27.2%) have experienced some
form of unwanted sexual contact
in their lifetime (Table 2.1). This
equates to over 32 million women
in the United States. The 12 month
prevalence of unwanted sexual
contact reported by women was
2.2%. Approximately 1 in 9 men
(11.7%) reported experiencing
unwanted sexual contact in his
lifetime, which translates to an esti-
mated 13 million men in the United
States (Table 2.2). The 12 month
prevalence of unwanted sexual
contact reported by men was 2.3%.

20 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
Non-Contact Unwanted
Sexual Experiences
Non-contact unwanted sexual expe-
riences were the most common
form of sexual violence experienced
by both women and men (Tables
2.1 and 2.2). One-third of women
(33.7%) experienced some type
of non-contact unwanted sexual
experience in their lifetime, and 1 in
33 women (3.0%) experienced this
in the 12 months prior to taking the
survey. This equates to 40 million
women in the United States for the
lifetime estimate and 3.5 million
women in the last 12 months.
Nearly 1 in 8 men (12.8%) reported
non-contact unwanted sexual
experiences in his lifetime, and 1 in
37 men (2.7%) experienced this type
of sexual violence in the 12 months
before taking the survey. These
numbers translate to 14 million men
in the United States who had these
experiences in their lifetimes and 3
million men in the last 12 months.
Prevalence of Rape and
Other Sexual Violence
by Race/Ethnicity
Approximately 1 in 5 Black (22.0%)
and White (18.8%) non-Hispanic
women, and 1 in 7 Hispanic women
(14.6%) in the United States have
experienced rape at some point in
their lives (Table 2.3). More than
one-quarter of women (26.9%)
who identified as American Indian
or as Alaska Native and 1 in 3
women (33.5%) who identified as
multiracial non-Hispanic reported
rape victimization in their lifetime
(Table 2.3). Just under half of Black
non-Hispanic (41.0%), White non-
Hispanic (47.6%), and American
Indian or Alaska Native (49.0%)
women reported sexual violence
other than rape in their lifetime and
more than half of multiracial non-
Hispanic women (58.0%) reported
these experiences in their lifetime.
Approximately 1 in 3 Hispanic
(36.1%) and Asian or Pacific
Islander (29.5%) women reported
sexual violence other than rape.
Between one-fifth and one-quarter
of Black non-Hispanic (22.6%),
White non-Hispanic (21.5%),
Hispanic (26.2%), and American
Indian or Alaska Native (20.1%) men
experienced sexual violence other
than rape in their lives (Table 2.4).

(15.7%) men and nearly one-third
of multiracial (31.6%) men in the
United States had these experi-
ences during their lifetime. The only
reportable estimate of rape was for

this group reported being raped at
some point in their lifetime.
Type of Perpetrator
in Lifetime Reports of
Sexual Violence
Rape
The majority of both female and
male victims of rape knew their
perpetrators. More than half of
female victims of rape (51.1%)
reported that at least one perpe-
trator was a current or former
intimate partner (Table 2.5). Four
out of 10 of female victims (40.8%)
reported being raped by an
acquaintance. Approximately 1 in
8 female victims (12.5%) reported
being raped by a family member,
and 2.5% by a person in a position
of authority. About 1 in 7 female
victims (13.8%) reported being
raped by a stranger. In terms of
lifetime alcohol/drug-facilitated
rape, half of female victims (50.4%)
were raped by an acquaintance,
while 43.0% were raped by an
intimate partner.

The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 23
Male victims most commonly
reported a known perpetrator
for all types of sexual violence
other than rape. Nearly half of
male victims reported an intimate
partner (44.8%) or an acquaintance
(44.7%) as a perpetrator in situa-
tions where the male was made
to penetrate someone else. The
majority of male victims of sexual
coercion (69.7%) reported an
intimate partner as a perpetrator.
For both unwanted sexual contact
(51.7%) and non-contact unwanted
sexual experiences (44.9%),
approximately 1 in 2 male victims
reported an acquaintance as a
perpetrator (Table 2.6).
Number of Perpetrators
in Lifetime Reports of
Sexual Violence
Among sexual violence victims,
the majority of both women and
men reported one perpetrator
in their lifetime. Almost three-
quarters of female rape victims
(71.2%) reported being raped by
one perpetrator. For female rape
victims, 1 in 6 (16.4%) reported
two perpetrators and 1 in 8 (12.4%)
reported three or more perpetra-
tors in their lifetime (Figure 2.1).
Almost half of female victims
(45.8%) of lifetime sexual violence
other than rape reported one
perpetrator, approximately
one-quarter (23.4%) reported
two perpetrators, and just under
one-third (30.8%) reported three
or more perpetrators (Figure 2.1).
For male victims of rape and sexual
violence other than rape, the large
majority (86.6% and 92.1%, respec-
tively) reported one perpetrator
in their lifetime (data not shown).
Too few male victims reported two
or more perpetrators to produce a
reliable estimate.
The majority of
female victims of
rape and sexual
violence other than
rape reported only
male perpetrators.
For males, the sex
of the perpetrator
varied across types
of sexual violence.
Sex of Perpetrator in
Lifetime Reports of
Sexual Violence
Most perpetrators of all forms of
sexual violence against women
were male. For female rape
victims, 98.1% reported only male
perpetrators. Additionally, 92.5% of
female victims of sexual violence
other than rape reported only male
perpetrators. For male victims, the
sex of the perpetrator varied by
the type of sexual violence expe-
rienced. The majority of male rape
victims (93.3%) reported only male
perpetrators. For three of the other
forms of sexual violence, a majority
of male victims reported only
female perpetrators: being made to
penetrate (79.2%), sexual coercion
(83.6%), and unwanted sexual
contact (53.1%). For non-contact
unwanted sexual experiences,
approximately half of male victims
(49.0%) reported only male perpe-
trators and more than one-third
(37.7%) reported only female
perpetrators (data not shown).

Age at the Time of
First Completed Rape
Victimization
More than three-quarters of
female victims of completed rape
(79.6%) were first raped before
their 25th birthday, with 42.2%
experiencing their first completed
rape before the age of 18 (29.9%
between 11-17 years old and 12.3%
at or before age 10) (Figure 2.2).
Approximately 1 in 7 female victims
(14.2%) experienced their first
completed rape between 25-34
years of age.
More than one-quarter of male
victims of completed rape (27.8%)
were first raped when they were
10 years old or younger (data not
shown). With the exception of the
youngest age category (i.e., age 10
or younger), the estimates for age
at first completed rape for male
victims in the other age groups
were based upon numbers too
small to calculate a reliable estimate
and therefore are not reported.
More than one-third
of women who were
raped as minors were
also raped as adults
compared to 14% of
women without an
early rape history.

Rape Victimization as a
Minor and Subsequent
Rape Victimization
More than one-third (35.2%)
of the women who reported a
completed rape before the age of
18 also experienced a completed
rape as an adult, compared to
14.2% of the women who did
not report being raped prior to
age 18 (Figure 2.3). Thus, the
percentage of women who were
raped as children or adolescents
and also raped as adults was
more than two times higher than
the percentage among women
without an early rape history.
Too few men reported rape
victimization in adulthood to
examine rape victimization as
a minor and subsequent rape
victimization in adulthood.

3: Stalking Victimization
28 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
How NISVS Measured Stalking
Stalking victimization involves a pattern of harassing or threatening tactics used by a
perpetrator that is both unwanted and causes fear or safety concerns in the victim. For the
purposes of this report, a person was considered a stalking victim if they experienced multiple
stalking tactics or a single stalking tactic multiple times by the same perpetrator and felt very
fearful, or believed that they or someone close to them would be harmed or killed as a result
of the perpetrator’s behavior.
Stalking tactics measured:
• Unwanted phone calls, voice or text messages, hang-ups
• Unwanted emails, instant messages, messages through social media
• Unwanted cards, letters, owers, or presents
• Watching or following from a distance, spying with a listening device, camera, or global
positioning system (GPS)
• Approaching or showing up in places such as the victim’s home, workplace, or school when
it was unwanted
• Leaving strange or potentially threatening items for the victim to nd
• Sneaking into victims’ home or car and doing things to scare the victim or let the victim
know the perpetrator had been there

3: Stalking Victimization
In the past decade, stalking
victimization has received greater
recognition as a problem affecting
both women and men in the
United States. Much of what
we have learned about stalking
is based on studies of intimate
partner violence and special popu-
lations, such as college students
(Fisher, et al., 2000). In recent
years, technological advances
have dramatically increased the
options available for commu-
nication between people. Less
is known about the extent to
which newer technologies (e.g.,
text messages, emails, instant
messages) have been used for
stalking and harassment of others.
Further, there are few recent
national level estimates of stalking
victimization (Basile, Swahn, Chen
& Saltzman, 2006; Baum, Catalano,
Rand, & Rose, 2009).
This section summarizes lifetime
and 12 month experiences of
stalking victimization among
women and men in the United
States, including characteristics
of the victimization experiences
such as the type of perpetrator, the
number and sex of perpetrators,
and age at the time of the first
stalking victimization.
Prevalence of Stalking
Victimization
Approximately 1 in 6 women
(16.2%) in the United States has
experienced stalking at some point
in her lifetime in which she felt
very fearful or believed that she
or someone close to her would
be harmed or killed as a result
(Table 3.1).2 This translates to
approximately 19.3 million adult
women in the United States. About
4%, or approximately 5.2 million
women, were stalked in the 12
months prior to taking the survey.
Approximately 1 in 19 men (5.2%)
in the United States (approximately
5.9 million) has experienced
stalking victimization at some
point during his lifetime in which
2Legal statutes vary regarding the requirement of victim fear during a stalking episode. Similarly, there is debate in the research community about
the necessity of requiring a criterion of fear in measures of stalking prevalence. If a criterion of fear is used, it is also not clear how much fear is
required to be considered a victim of stalking. Similar to the National Violence Against Women Survey (Tjaden & Thoennes, 2000), we used a
conservative definition in this report to estimate stalking prevalence which required the victim to report having felt very fearful or concern that
harm would come to the victim or someone close to him/her as a result of the perpetrator’s behavior. In stalking situations, victims may vary in
their assessment of the danger of the situation and consequently report varying levels of fear, such as low or no fear even if the situation would
cause a “reasonable person” to feel afraid. Using a less conservative definition of stalking, which considers any amount of fear (i.e., a little fearful,
somewhat fearful, or very fearful), 1 in 4 women (25.0%) and 1 in 13 men (7.9%) in NISVS reported being a victim of stalking in their lifetime, with
6.5% and 2.0% of women and men, respectively, reporting stalking in the 12 months prior to taking the survey.
1 in 6 women and 1 in 19 men in the U.S. have experienced stalking
at some point in their lives in which they felt very fearful or believed

he felt very fearful or believed that
he or someone close to him would
be harmed or killed as a result, and
1.3% of men (about 1.4 million)
reported being stalked in the 12
months prior to taking the survey.
Prevalence of Stalking
Victimization by Race/
Ethnicity
In the United States, approximately
1 in 5 Black non-Hispanic women
experienced stalking in her lifetime
(Table 3.2). The prevalence of
stalking for White non-Hispanic
and Hispanic women was similar
(1 in 6 and 1 in 7, respectively).
Additionally, approximately 1 in 3
multiracial non-Hispanic and 1 in 4
American Indian or Alaska Native
women reported being stalked at
some point during their lives.
Approximately 1 in 17 Black
non-Hispanic men in the United
States experienced stalking in their
lifetime (Table 3.3). The prevalence
of stalking for White non-Hispanic
and Hispanic men was similar
(about 1 in 20). The estimates for
the other racial/ethnic groups of
men were based upon numbers too
small to produce a reliable estimate
and therefore are not reported.
Tactics Used in Lifetime
Reports of Stalking
Victimization
A variety of tactics were used
to stalk victims. More than
three-quarters of female stalking
victims (78.8%) reported receiving
unwanted phone calls, including
voice or text messages, or hang
ups (Figure 3.1). More than half of
female victims (57.6%) reported
being approached, such as at their

Male victims were primarily stalked by
intimate partners or acquaintances.
home or work, and more than
one-third (38.6%) were watched,
followed or tracked with a listening
or other device.
Similarly, about three-quarters
of male victims (75.9%) reported
receiving unwanted phone calls,
voice or text messages, or hang ups
(Figure 3.2). Just under half (43.5%)
reported being approached by the
perpetrator. Nearly one-third of
male victims (31.0%) reported being
watched, followed, or tracked.
Type of Perpetrator
in Lifetime Reports of
Stalking Victimization
For both female and male victims,
stalking was often committed by
people they knew or with whom
they had a relationship. Two-thirds
of the female victims of stalking
(66.2%) reported stalking by a
current or former intimate partner
and nearly one-quarter (24.0%)
reported stalking by an acquain-
tance (Figure 3.3). About 1 in 8
female victims (13.2%) reported
stalking by a stranger.
Approximately 4 out of 10 male
stalking victims (41.4%) reported
that they had been stalked by an
intimate partner in their lifetime,
with a similar proportion indi-
cating that they had been stalked
by an acquaintance (40.0%) (Figure
3.4). Nearly one-fifth of male
victims (19.0%) reported stalking
by a stranger and 5.3% reported
being stalked by a family member.

Number of Perpetrators
in Lifetime Reports of
Stalking Victimization
The majority of both women
and men reported that they
experienced stalking from one
perpetrator in their lifetime, 76.0%
and 82.2%, respectively (Figure 3.5).
Approximately 1 in 6 female victims
(17.0%) experienced stalking by
two perpetrators, and 1 in 14 (7.1%)
had experienced stalking by three
or more perpetrators. Among men,
about 1 in 10 (9.6%) experienced
stalking by two perpetrators.
Sex of Perpetrator in
Lifetime Reports of
Stalking Victimization
Among female stalking victims,
82.5% reported being stalked by
only male perpetrators in their
lifetime; 8.8% reported only
female perpetrators; and 4.6%
reported having been stalked by
both male and female perpetra-
tors (data not shown).
Among male stalking victims,
almost half (44.3%) reported being
stalked by only male perpetrators
while a similar proportion (46.7%)
reported being stalked by only
female perpetrators. About 1 in
18 male stalking victims (5.5%)
reported having been stalked by
both male and female perpetrators
in his life (data not shown).
More than half of
female victims and
more than one-third
of male victims
were stalked before
the age of 25.
Age at the Time of First
Stalking Victimization
More than half of female victims
and more than one-third of male
victims of stalking indicated that
they were stalked before the age
of 25 (Figures 3.6 and 3.7). About
1 in 5 female victims and 1 in 14
male victims had experienced
stalking between the ages of 11
and 17. For both female and male
victims, more than one-quarter
(28.5% and 29.6%, respectively)
reported that their first stalking
victimization occurred between
25 to 34 years of age.

How NISVS Measured Intimate Partner Violence
Five types of intimate partner violence were measured in NISVS. These include sexual
violence, stalking, physical violence, psychological aggression, and control of reproductive/
sexual health.
• Sexual violence includes rape, being made to penetrate someone else, sexual coercion,
unwanted sexual contact, and non-contact unwanted sexual experiences as described in
Section 2.
• Physical violence includes a range of behaviors from slapping, pushing or shoving to
severe acts such as being beaten, burned, or choked.
• Stalking victimization involves a pattern of harassing or threatening tactics used by a
perpetrator that is both unwanted and causes fear or safety concerns in the victim as
described in Section 3.
• Psychological aggression includes expressive aggression (such as name calling,
insulting or humiliating an intimate partner) and coercive control, which includes
behaviors that are intended to monitor and control or threaten an intimate partner.
• Control of reproductive or sexual health includes the refusal by an intimate partner
to use a condom. For a woman, it also includes times when a partner tried to get her
pregnant when she did not want to become pregnant. For a man, it also includes times
when a partner tried to get pregnant when the man did not want her to become pregnant.
The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 37
4: Violence by an Intimate Partner
Intimate partner violence includes
physical violence, sexual violence,
threats of physical or sexual
violence, stalking and psycho-
logical aggression (including
coercive tactics) by a current or
former intimate partner. Intimate
partner violence may occur
among cohabitating or non-
cohabitating romantic or sexual
partners and among opposite or
same sex couples. Previous large
scale surveys of intimate partner
violence have primarily examined
only certain aspects of intimate
partner violence (e.g., physical or
sexual violence) or have examined
these forms of intimate partner
violence within the context of
crime or public safety. More recent
smaller scale surveys have covered
selected populations, for example
schools, colleges, individual states
and, in general, have included a
limited number of questions. By
comparison, the National Intimate
Partner and Sexual Violence Survey
includes a broad range of behavior-
ally specific questions to capture
the full burden of physical, sexual,
and psychological violence by an
intimate partner, as well as stalking.
Respondents were asked about
their relationship at the time the
perpetrator first committed any
violence against them. Incidents
perpetrated by a current or former
intimate partner are considered
violence by an intimate.
This section summarizes lifetime
and 12 month experiences of
intimate partner violence among
women and men in the United
States, including estimates for
sexual violence, stalking, physical
violence, psychological aggres-
sion (expressive aggression and
coercive control), and control of
reproductive or sexual health by
an intimate partner. This section
also includes the overlap of lifetime
rape, physical violence, and
stalking by an intimate partner;
lifetime prevalence estimates
of these forms of violence by
self-identified race/ethnicity; and
information on the characteristics
of the victimization experiences,
including the type of perpetrators,
the number of perpetrators, and
age at the time of the first intimate
partner violence victimization.
Detailed information regarding the
impact of intimate partner violence
is included in Section 5.

Prevalence of Rape,
Physical Violence,
and/or Stalking by an
Intimate Partner
Prevalence Among Women
More than one-third of women
in the United States (35.6% or
approximately 42.4 million)
have experienced rape, physical
violence, and/or stalking by an
intimate partner at some point
in their lifetime (Table 4.1). One
in 3 women (32.9%) has expe-
rienced physical violence by an
intimate partner and nearly 1 in
10 (9.4%) has been raped by an
intimate partner in her lifetime.
Approximately 5.9%, or almost
7.0 million women in the United
States, reported experiencing these
forms of violence by an intimate
partner in the 12 months prior to
taking the survey.
Nearly 3 in 10 women in the United
States (28.8% or approximately
34.3 million) have experienced
rape, physical violence, and/or
stalking by an intimate partner and
reported at least one measured
impact related to experiencing
these or other forms of violent
behavior in that relationship. The
impact estimate is broader than
the experience of rape, physical
violence, and/or stalking because
violent acts often do not occur
in isolation and are frequently
experienced in the context of other
violence committed by the same
perpetrator. More detailed informa-
tion regarding the prevalence and
distribution of IPV-related impacts
is described in Section 5.
Prevalence Among Men
More than 1 in 4 men in the United
States (28.5%) has experienced
rape, physical violence, and/or
stalking by an intimate partner at
some point in their lifetime. Most
of the violence reported by men
was physical violence; only 2.1%
reported experiencing stalking by
an intimate partner (Table 4.2). An
estimated 1 in 20 men in the United
States (5.0% or about 5.7 million)
reported experiencing rape,
physical violence, and/or stalking
by an intimate partner in the 12
months prior to taking the survey.
About 1 in 10 men in the United
States (9.9% or an estimated 11.2
million) has experienced rape,
physical violence, and/or stalking
by an intimate partner and
reported at least one measured
impact related to these or other
forms of violent behavior in
that relationship.
Prevalence of Intimate
Partner Rape, Physical
Violence, and/or
Stalking by Race/
Ethnicity
Prevalence Among Women
Approximately 4 out of every 10
non-Hispanic Black women, 4 out
of every 10 American Indian or
Alaska Native women (43.7% and
46.0%, respectively), and 1 in 2
multiracial non-Hispanic women
(53.8%) have been the victim of
rape, physical violence, and/or
stalking by an intimate partner in
their lifetime (Table 4.3). Among
the other racial/ethnic groups
of women, about one-third of
White non-Hispanic women
(34.6%), more than one-third of
Hispanic women (37.1%), and
about one-fifth of Asian or Pacific
Islander non-Hispanic women
(19.6%) in the United States
reported that they have been the
victim of rape, physical violence,
and/or stalking by an intimate
partner in their lifetime.
Prevalence Among Men
Nearly half (45.3%) of American
Indian or Alaska Native men and
almost 4 out of every 10 Black
and multiracial non-Hispanic men
(38.6% and 39.3%, respectively) in
the United States reported experi-
encing rape, physical violence, and/
or stalking by an intimate partner
during their lifetime (Table 4.4).
The estimated prevalence of these
forms of violence by an intimate
partner among Hispanic and White
non-Hispanic men was 26.6% and
28.2%, respectively.

Reports of Violence by
an Intimate Partner
Among all women who experi-
enced rape, physical violence, and/
or stalking by an intimate partner
in their lifetime, 63.8% experienced
one form of violence by an intimate
partner; 56.8% experienced
physical violence alone, 4.4%
experienced rape alone, and 2.6%
experienced stalking alone (Figure

enced rape and physical violence,
14.4% experienced physical
violence and stalking, and 12.5%
experienced all three forms of IPV.
Among all men who experienced
rape, physical violence, and/or
stalking by an intimate partner in
their lifetime, approximately 92%
experienced physical violence
alone, while 6.3% experienced
both physical violence and stalking
by an intimate partner (Figure

Sexual Violence by an
Intimate Partner
Prevalence Among Women
Nearly 1 out of 10 women in the
United States (9.4% or approxi-
mately 11.1 million) has been
raped by an intimate partner in her
lifetime (Table 4.5). More specifi-
cally, 6.6% of women reported
completed forced penetration by
an intimate partner, 2.5% reported
attempted forced penetration,
and 3.4% reported alcohol/drug
facilitated rape. Approximately 1
in 6 women (16.9% or nearly 19
million) has experienced sexual
violence other than rape by an
intimate partner in her lifetime; this
includes sexual coercion (9.8%),
unwanted sexual contact (6.4%)
and non-contact unwanted sexual
experiences (7.8%).
In the 12 months prior to taking
the survey, 0.6% or an estimated
686,000 women in the United States
indicated that they were raped by
an intimate partner, and 2.3% or an
estimated 2.7 million women experi-
enced other forms of sexual violence
by an intimate partner.
Prevalence Among Men
Too few men reported rape by
an intimate partner to produce
reliable prevalence estimates.
Approximately 1 in 12 men in the
United States (8.0% or approxi-
mately 9 million) has experienced
sexual violence other than rape by
an intimate partner in his lifetime
(Table 4.6). This includes being
made to penetrate an intimate
partner (2.2%), sexual coercion
(4.2%), unwanted sexual contact
(2.6%) and non-contact unwanted
sexual experiences (2.7%). In the 12
months prior to taking the survey,
2.5% or nearly 2.8 million men
experienced sexual violence other
than rape by an intimate partner.

Prevalence Among Men
Approximately 1 in 4 men in the
United States (25.7% or about 29
million) has been slapped, pushed
or shoved by an intimate partner
in his lifetime, and 4.5% or approxi-
mately 5 million men, reported
experiencing these behaviors in
the 12 months prior to taking the
survey (Table 4.8).
Nearly 1 in 7 men in the United
States (13.8% or approximately 15.6
million) has experienced severe
physical violence by an intimate
partner in his lifetime. About 9.4%
of men have been hit with a fist
or something hard by an intimate
partner, 4.3% reported being
kicked, and less than 3% reported
each of the other forms of severe

5: Impact of Intimate Partner Violence
52 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
How NISVS Measured the Impact of Intimate Partner Violence
For each perpetrator of intimate partner violence, respondents were asked about whether
they had experienced:
• being fearful
• being concerned for safety
• symptoms of post-traumatic stress disorder (PTSD)
-having nightmares
-trying hard not to think about it or avoiding being reminded of it
-feeling constantly on guard, watchful, or easily startled
-feeling numb or detached from others, activities, or surroundings
• being injured
• needing healthcare as a result of the intimate partner violence experienced
• needing housing services
• needing victim’s advocate services
• needing legal services
• contacting a crisis hotline
• missing days of work or school because of the intimate partner violence experienced
• for those reporting rape by an intimate partner – contracting a sexually
transmitted infection or becoming pregnant (for women)
The questions were assessed in relation to specic perpetrators, without regard to the time
period in which they occurred. Because violent acts often do not occur in isolation and are
frequently experienced in the context of other violence committed by the same perpetrator,
questions regarding the impact of the violence were asked in relation to all forms of violence
(sexual violence, physical violence, stalking, expressive aggression, coercive control, and
reproductive control) committed by the perpetrator in that relationship. Such information
provides a better understanding of how individual and cumulative experiences of violence
interact to result in harm to victims and provides a more nuanced understanding of the
overall impact of violence.

5: Impact of Intimate Partner Violence
Factors beyond whether a person
has ever experienced intimate
partner violence are important to
measure and understand in order
to achieve a more complete picture
of the true burden of intimate
partner violence. Evidence from
several studies suggests a dose-
response effect of violence; as the
frequency and severity of violence
increases, the impact of the
violence on the health of victims
also becomes increasingly severe
(Campbell, 2002; Cox, Coles, Nortje,
Bradley, Chatfield, Thompson, &
Menon, 2006). However, given that
intimate partner violence victimiza-
tion can range from a single act
experienced once to multiple acts,
including acts of severe violence
over the course of many years, it is
difficult to represent the variation
in severity experienced by victims
in a straightforward manner. To
this end, NISVS included a number
of questions to assess a range of
impacts that victims of intimate
partner violence may have expe-
rienced. This information provides
not only a measure of the severity
of the violence experienced, but
also documents the magnitude of
negative impacts to better focus
preventive services and response.
Impact was measured using a set
of indicators that represent a range
of direct impacts that may be
experienced by victims of intimate
partner violence. IPV-related
impact was assessed in relation
to specific perpetrators, without
regard to the time period in which
impact occurred, and asked in
relation to the forms of intimate
partner violence experienced
(sexual violence, physical violence,
stalking, expressive aggression,
coercive control, and control of
reproductive or sexual health) in
that relationship.

How NISVS Measured Health Outcomes
Before being asked about sexual violence, stalking, and intimate partner violence, all survey
participants were asked the following health related questions:
• Have you ever been told by a doctor, nurse, or other health professional that you had…
-Asthma?
-Irritable bowel syndrome or IBS?
-Diabetes?
-High blood pressure?
• Do you have…
-Frequent headaches?
-Chronic pain?
-Diculty sleeping?
• Are any of your activities limited in any way because of physical, mental, or emotional
problems?
• Would you say that in general your physical health is excellent, very good, good, fair, or poor?
• Would you say that in general your mental health is excellent, very good, good, fair, or poor?
The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 61
6: Physical and Mental Health Outcomes
by Victimization History
Previous research suggests that
victims of intimate partner and
sexual violence make more visits to
health providers over their lifetime,
have more hospital stays, have
longer duration of hospital stays,
and are at risk of a wide range of
physical, mental, reproductive, and
other health consequences over
their lifetime than non-victims
(Basile & Smith, 2011; Black, 2011).
Many studies have documented
increased risk for a number of
adverse physical, mental, reproduc-
tive, and other health outcomes
among those who have experi-
enced intimate partner violence
and sexual violence. A smaller body
of research has also documented
that stalking has a negative
impact on health (Davis, Coker, &
Sanderson, 2002). Most studies that
have evaluated the adverse health
impact of intimate partner violence
and sexual violence are based on
female victims of such violence;
less is known about the risk for
adverse health events among men
(Breiding, Black, & Ryan, 2008;
Smith & Breiding, 2011).
The cross-sectional nature
of NISVS does not allow for a
determination of causality or the
temporal precedence of violence
victimization and associated
health outcomes. However, there
may be a number of potential
mechanisms by which violence
is related to health over one’s
lifetime (Black, 2011). For example,
some health conditions may result
directly from a physical injury.
Other health conditions may result
from the adoption of health-risk
coping behaviors such as smoking
and the harmful use of alcohol
or drugs (Campbell, 2002; Coker,
Davis, Arias, Desai, Sanderson,
Brandt, & Smith, 2002). Another
explanation for the association
between violence victimization
and poor health is the harmful
biologic response to chronic stress
associated with experiences of
violence (Sutherland, Bybee, &
Sullivan, 2002).
This section compares the preva-
lence of various health outcomes
among persons with a lifetime
history of rape by any perpetrator,
stalking by any perpetrator, or
physical violence by an intimate
partner in relation to those who
have not experienced these forms
of violence in their lifetime.

blood pressure, the prevalence
of adverse mental and physical
health outcomes was significantly
higher among women with a
history of rape or stalking by any
perpetrator, or physical violence by
an intimate partner, compared to
women without a history of these
forms of violence (Table 6.1). This
includes a higher reported preva-
lence of asthma, irritable bowel
syndrome, diabetes, frequent
headaches, chronic pain, difficulty
sleeping, and activity limitations.
The percentage of women who
considered their physical or mental
health to be poor was almost three
times higher among women with
a history of violence compared
to women who have not experi-
enced these forms of violence. The
observed differences in the preva-
lence of health outcomes were in
most cases quite large. The largest
differences in prevalence of health
outcomes between those with and
without a violence history were
observed for difficulty sleeping,
activity limitations, chronic pain,
and frequent headaches.
Prevalence Among Men
Compared to men without a
history of rape or stalking by any
perpetrator, or physical violence
by an intimate partner, men with
such histories had significantly
higher prevalence of frequent
headaches, chronic pain, difficulty
sleeping, activity limitations, and
consider their physical and mental
health to be poor (Table 6.2). There
were no significant differences
between the two groups of men in
the prevalence of asthma, irritable
bowel syndrome, diabetes, or high
blood pressure.

7: Sexual Violence, Stalking, and Intimate
Partner Violence by State
The National Intimate Partner and
Sexual Violence Survey is designed
to provide data for states as well
as the nation. Although some
individual states have collected
data at various points during
the past decade, most states do
not have state prevalence data
on sexual violence, stalking, and
intimate partner violence. State-
level data on these forms of
violence help to define the nature
and burden of the problem within
a state and can be used to inform
prevention planning and response.
They can also help guide and
evaluate progress toward reducing
the substantial health, social, and
economic costs associated with
sexual violence, stalking, and
intimate partner violence.
Lifetime estimates of the preva-
lence of sexual violence, stalking,
and intimate partner violence are
presented by state in this section.
These estimates reflect the propor-
tion of people in a given state
population with a history of sexual
violence, stalking, and intimate
partner violence. The lifetime
victimization experiences reported
by individuals in a given state may
include violence that occurred else-
where. These estimates, however,
provide important information
about the proportion of women
and men with victimization histo-
ries currently residing in a state.
Given the potential long-term
health consequences of victimiza-
tion and the likelihood of ongoing
health and service needs, these
estimates can help states better
understand the burden of violence
in their populations. This informa-
tion can also be used to inform
prevention planning, resource
allocation, and advocacy efforts.
Separate tables are provided for
women and men. When reportable,
prevalence estimates are presented
for rape, sexual violence other
than rape, and stalking by any
perpetrator. State-level prevalence
estimates of rape, physical violence,
and/or stalking by an intimate
partner are also provided along with
the prevalence of lifetime intimate
partner violence victimization with
IPV-related impact. State-level 12
month estimates of sexual violence,
stalking, and intimate partner
violence are not included in this
first report due to small numbers. In
order to be able to provide reliable
state-level annual estimates, many
of the 12 month prevalence rates
will be released in subsequent
reports as moving averages over
multiple years.
The findings in the detailed state
tables show a range in lifetime
victimization experiences of rape,
sexual violence other than rape,
and intimate partner violence
across states. Lifetime estimates
for women ranged from 11.4%
to 29.2% for rape; 28.9% to 58%
for sexual violence other than
rape; and 25.3% to 49.1% for rape,
physical violence, and/or stalking
by an intimate partner. For men,
lifetime estimates ranged from
10.8% to 33.7% for sexual violence
other than rape; and 17.4% to
41.2% for rape, physical violence,
and/or stalking by an intimate
partner. Confidence intervals for
these estimates are available at
www.cdc.gov/violenceprevention/
nisvs. For women, the percentage
reporting rape, physical violence,
and/or stalking by an intimate
partner and experiencing at least
one measured impact from these
or other forms of violence in the
relationship ranged from 19.3% to
39.5%. Data on IPV-related impact
for men are not reported due to
small numbers resulting in unreli-
able estimates.
When reviewing state level data
it is important to recognize that
although there are variations
between states, the purpose in
presenting these data is not to
compare states but rather to help
states understand the burden of
the problem in their populations.
The states, themselves, vary in a
number of ways, including in their
demographic characteristics (e.g.,
age distribution), social, economic
and cultural characteristics, as well
as external stressors (e.g., economic
downturn, job loss, poverty), and
other factors.

Highlights and Cross-
Cutting Findings
The findings in this report indicate
that sexual violence, stalking, and
intimate partner violence continue
to be important public health
issues affecting many women
and men in the United States.
Although no demographic group is
immune to these forms of violence,
consistent patterns emerged with
respect to the subpopulations in
the United States that are most
heavily affected. Consistent with
previous national studies (Tjaden
& Thoennes, 2000), the findings in
this report indicate that women are
heavily affected by sexual violence,
stalking, and intimate partner
violence. Many of these forms
of violence are first experienced
during childhood and remain
prevalent among young adults
aged 18-24. Furthermore, victims
who reported rape prior to 18 years
of age had a higher prevalence of
subsequent victimization of rape as
an adult. These data provide further
evidence that when victimization
occurs, particularly when it occurs
in childhood, it is often repeated
in adulthood (Tjaden & Thoennes,
2000; Smith, White, & Holland, 2003;
Maker, Kemmelmeier, & Peterson,
2001; West, Williams, & Seigel, 2000).
For all types of violence examined
in this report, the majority of both
female and male victims had one
perpetrator. Across all forms of
violence, the majority of female
victims reported that the perpetra-
tors were male. Male rape victims
and male victims of non-contact
unwanted sexual experiences
reported predominantly male
perpetrators. Nearly half of male
stalking victims also reported
perpetration by a male. Male
victims of other forms of violence
reported predominantly female
perpetrators. Across all subpopula-
tions and all forms of violence,
the vast majority of victims knew
their perpetrator – for women,
perpetrators were often current
or former intimate partners and
for men they were often acquain-
tances. A substantial number of
female victims of intimate partner
violence experienced multiple
forms of violence (e.g., rape,
physical violence, and stalking) in
their lifetime. Among male victims
of intimate partner violence, the
majority experienced physical
violence, with a smaller percentage
of men having experienced both
physical violence and stalking.
Additionally, racial and ethnic
minority women and men continue
to bear a relatively heavier burden
of sexual violence, stalking, and
intimate partner violence. This
is likely a reflection of the many
stressors that racial and ethnic
minority communities continue to
experience. For example, a number
of social determinants of mental
and physical health, such as low
income and limited access to educa-
tion, community resources, and
services, likely play important roles.
These findings also confirm and
extend the literature documenting
that exposure to sexual violence,
stalking, and intimate partner
violence has significant adverse
consequences for physical and
mental health. The severity and
range of health consequences were
greater for victims of these forms of
violence than for persons without a
history of victimization. This is the
first U.S. survey that enables us to
document and track these conse-
quences on a national scale.
For many states, the findings in
this report provide the first reliable
and representative state-level
prevalence estimates for sexual
violence, stalking, and intimate
partner violence. State-level data
reveal variation across states for
all types of violence examined.
Demographic composition
and other factors may play an
important role in the nature and
magnitude of violence within and
across states.
Comparison of
Prevalence Estimates
to Previous National
Studies
Differences in methodology
between the National Intimate
Partner and Sexual Violence
Survey and other population-
based surveys or data sources
make comparisons of prevalence
estimates difficult. NISVS uses
a combination of strategies to
enhance accuracy of reporting
and safety of respondents. The
extent to which similar strategies
are utilized in other surveys that
measure violent victimization
varies. For example, to facilitate
recall, NISVS is designed to be
consistent with the way victims
tend to recall experiences of
violence – all behaviors are
linked to a specific perpetrator
(e.g., ex-husband, acquaintance,
stranger). All questions are asked
within the context of that perpe-
trator. Additionally, as described
in the background section of this
report, NISVS uses a number of
methods that are designed to
safely maximize disclosure of sensi-
tive information. A key example
is that one adult is randomly
selected from each household and
the specific survey content is only
disclosed to that adult; no other
household members are aware of
the specific questions being asked.
The respondent then answers
questions about their own experi-
ences with violence and they do
not have to inform anyone else in
the household about the nature
of the questions. Other features of
NISVS also are designed to reduce
underreporting, such as use of
only female interviewers, creating
a social distance by interviewing
over the telephone instead of in
person, use of extensive introduc-
tions to questions asking about
sensitive topics, and specialized
training for interviewers to prepare
them to collect sensitive informa-
tion. The NISVS procedures are
intended to enhance respondents’
comfort and safety so that they are
willing and able to disclose their
victimization experiences.
Other differences between NISVS
and other surveys may include
differing contexts for survey
questions (e.g., health, relationship,
or crime), differences in question
wording, and differences in the
number and range of victim-
ization experiences included
in the violence measures. For
example, in addition to forced
penetration, the findings for rape
in this report include attempted
forced penetration and alcohol/
drug-facilitated forced penetration
in the calculation of the overall
prevalence estimate for rape. The
differences between the findings
in this survey and other similar
surveys could also be due, in
part, to differing sampling strat-
egies (e.g., sampling cell phones);
differing methods used to produce
representative estimates (e.g.,
weighting); and differing methods
of data collection (e.g., in-person
versus telephone) and who is inter-
viewed (e.g., victims only or victims
and proxies).
As an example of prevalence
differences between the National
Intimate Partner and Sexual
Violence Survey and other surveys,
the lifetime prevalence estimate of
rape for men in this report is lower
than what has been reported in
other surveys (e.g., for forced sex
more broadly) (Basile, Chen, Black,
& Saltzman, 2007). This could be
due in part to the National Intimate
Partner and Sexual Violence Survey
making a distinction between
rape and being made to penetrate
someone else. Being made to
penetrate is a form of sexual victim-
ization distinct from rape that is
particularly unique to males and, to
our knowledge, has not been explic-
itly measured in previous national
studies. It is possible that rape
questions in prior studies captured
the experience of being made to
penetrate someone else, resulting
in higher prevalence estimates for
male rape in those studies.
The findings in this report also
show a higher prevalence of
stalking among women and
men than previous national
surveys (Baum et al., 2009; Tjaden
& Thoennes, 2000). Although
victims reported experiencing the
conventional forms of stalking (e.g.,
watching and showing up unex-
pectedly), the higher prevalence
estimates in the National Intimate
Partner and Sexual Violence Survey
may largely be due to the inclu-
sion of stalking tactics related to
newer technologies (e.g., persistent
cell phone texting) that did not
exist as a stalking modality when
some of the previous studies were
conducted. Cell phone ownership
has grown tremendously in the
last several years. Furthermore,
advancements in wireless tech-
nology have led to Internet access
that is no longer dependent upon
the use of home or business
computers. For many people,
these technologies provide greater
convenience and easier acces-
sibility to others; however, this
growth in technology may have
also increased the ease of engaging
in certain stalking behaviors.
The prevalence estimates for
intimate partner violence reported
here also differ from those reported
in other similar national surveys.
The estimates are higher for both
men and women, but particularly
for physical violence victimization
of men. In addition to the previ-
ously mentioned changes related
to the measurement of stalking
and sexual violence, which are
components of intimate partner
violence, another key factor may
account for the differences in
prevalence estimates. Specifically,
some previous national surveys
84 The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report
The National Intimate Partner and Sexual Violence Survey | 2010 Summary Report 85
have asked respondents to identify
whether they have experienced
physical violence by any perpe-
trator, and then respondents are
subsequently asked whether
the perpetrator was an intimate
partner. By contrast, respondents in
the National Intimate Partner and
Sexual Violence Survey are asked
whether they have experienced
physically violent acts specifically
by a romantic or sexual partner.
This difference may have increased
reporting by focusing respondents
on intimate partner violence
specifically rather than physically
violent acts that may have been
perpetrated by others, such as
strangers and acquaintances. This
may particularly be true for men as
they are more likely to have experi-
enced physical violence outside the
context of an intimate relationship
(Krug, Dahlberg, Mercy, Zwi, &
Lozano, 2002).
Limitations
The findings of this report are
subject to a number of limitations.
Random digit dial telephone
surveys face two major issues that
have the potential to affect the
representativeness of the sample
population. This includes declining
response rates and an increasing
number of households without
landline telephones (Peytchev,
Carley-Baxter, & Black, 2011). While
the overall response rate for the
2010 National Intimate Partner
and Sexual Violence Survey was
relatively low, the cooperation
rate was high. A number of efforts
were also made to mitigate the
potential for non-response and
non-coverage bias. These include
a non-response follow-up in
which randomly selected non-
responders were re-contacted
and offered an increased incentive
for participation. In addition,
the inclusion of a cell-phone
component provided increased
coverage of a growing population
that would have otherwise been
excluded. The cell-phone only
population tends to be young,
low income, and comprised of
racial/ethnic minorities (Peytchev,
Carley-Baxter, & Black, 2011).
Importantly, these demographic
groups have higher prevalence
of sexual violence, stalking, and
intimate partner violence.
Follow-up questions were designed
to reflect the victim’s experience
with each perpetrator across the
victim’s lifetime. There are several
limitations associated with how
these questions were asked. First,
respondents were asked about the
impact from any of the violence
inflicted by each perpetrator.
Therefore, it is not possible to
examine the impact of specific
violent behaviors. However,
results from the cognitive testing
process for the National Intimate
Partner and Sexual Violence
Survey suggested that victims who
experienced multiple forms of
violence with a perpetrator would
have a difficult time distinguishing
which type of violence from that
perpetrator resulted in a particular
type of impact. Second, because
we used victims’ reports of the age
and relationship at the time any
violence started with each perpe-
trator it was not always possible
to assess the age or relationship at
the time specific types of violent
behavior occurred. Based on the
data we have about the relation-
ship at the first victimization and
last victimization, we estimate that
less than 3% of perpetrators had
a relationship with the victim that
changed categories over time (e.g.,
from acquaintance to intimate
partner). All of the estimates in
this report reflect the relationship
at the time the perpetrator first
committed any violence against
the victim.
Even though the National Intimate
Partner and Sexual Violence
Survey captures a full range of
victimization experiences, the
estimates reported here are likely
to underestimate the prevalence
of sexual violence, stalking, and
intimate partner violence for a
number of reasons. These include:
1) potential respondents that
are currently involved in violent
relationships may not participate
in the survey or fully disclose the
violence they are experiencing
because of concern for their safety;
2) although the survey gathers
information on a wide range of
victimizations, it is not feasible
to measure all of the violent
behaviors that may have been
experienced; 3) given the sensitive
nature of these types of violence
it is likely that some respondents
who had been victimized did not
feel comfortable participating or
did not feel comfortable reporting
their experiences because of the
social stigma associated with
being a victim of these forms of
violence; 4) although potentially
mitigated by the use of a cell-
phone sample, RDD surveys may
not capture populations living in
institutions (e.g., prisons, nursing
homes, military bases, college
dormitories), or those who may be
living in shelters, or homeless and
transient; and 5) it is possible that
some respondents forgot about
violence experiences that were less
severe in nature or that occurred
long ago.
In addition to the possible causes
of underestimation of the preva-
lence, it is important to consider
the limitations of self report data
and that errors in recall or reluc-
tance to discuss specific types of
violence or perpetrators might
impact the accuracy of estimates
in unpredictable ways and in a
manner that could potentially vary
across subgroups of victims (e.g.,
by age or sex). Also, the reader
is cautioned against making
comparisons across groups or
across states because apparent
variation in estimates might not
reflect statistically meaningful
differences. Even with these limita-
tions, population-based surveys
that collect information directly
from victims remain one of the
most important sources of data
on sexual violence, stalking, and
intimate partner violence, particu-
larly for capturing victimization
experiences that are not likely to
come to the attention of police,
that may not be considered a
crime by victims, or do not require
treatment by a health provider.
Population-based surveys that are
carefully conducted, with well-
trained interviewers who are able
to build rapport and trust with
participants, are essential to the
collection of valid data and the
well-being of respondents.

9: Implications for Prevention
The findings in this report
underscore the heavy toll that
sexual violence, stalking, and
intimate partner violence places
on women, men, and children in
the United States. Given the scope
and impact of sexual violence,
stalking, and intimate partner
violence, it is critical that feasible,
evidence-informed actions are
taken to prevent and respond to
these problems. Collective action is
needed to implement prevention
approaches, ensure appropriate
responses, and support these efforts
based on strong data and research.
Implement Prevention
Approaches
The goal of public health is to
prevent violence from occurring in
the first place. The following primary
prevention strategies are scientifi-
cally credible, can potentially impact
multiple forms of sexual violence,
stalking and intimate partner
violence, and represent areas where
states and communities can make
reasonable investments.
Promote Healthy, Respectful
Relationships Among Youth
Relationships with Parents
Building healthy parent-child
relationships can address a range
of risk factors for sexual violence,
stalking, and intimate partner
violence. These relationships
can benefit from efforts to build
positive, effective parenting skills;
include and support fathers;
increase positive family relation-
ships and interactions; and develop
emotionally supportive familial
environments, which facilitate
respectful interactions and open
communication. Further, parents
who model healthy, respectful
intimate relationships free from
violence or aggression foster
these relationship patterns in their
children. It is also important to give
adults, particularly parents, the
skills and resources to prevent child
sexual abuse.
Relationships with Peers and
Dating Partners
Characteristics of respectful
relationships include: a belief in
nonviolent conflict resolution;
effective communication and
conflict resolution skills; the ability
to negotiate and adjust to stress
and safely manage emotions such
as anger and jealousy; and a belief
in a partner’s right to autonomy,
shared decision-making, and
trust. From preschool through
the teen years, young people are
refining the skills they need to
form positive relationships with
others. It is important to promote
healthy relationships among young
people and prevent patterns of
dating violence that can last into
adulthood. It is also important to
reinforce respectful relationships
among peers to prevent sexual
harassment and bullying.
Prevention strategies that engage
parents and youth in skill-building
activities and encourage or reward
respectful, healthy peer interactions
and dating relationships can be
implemented in the home, commu-
nity, or school to ensure more youth
experience and practice healthy
relationships during this key devel-
opmental phase.
Address Beliefs, Attitudes,
and Messages that Condone,
Encourage, or Facilitate
Sexual Violence, Stalking, or
Intimate Partner Violence
The promotion of respectful,
nonviolent relationships is not just
the responsibility of individuals
and partners, but also of the
communities and society in which
they live. It is important to continue
addressing the beliefs, attitudes
and messages that are deeply
embedded in our social structures
and that create a social climate that
condones sexual violence, stalking,
and intimate partner violence.
One way is through norms
change. Societal and community
norms, policies, and structures
create environments that can
support or undermine respectful,
nonviolent relationships. Such
beliefs and social norms are rein-
forced by media messages that
portray sexual violence, stalking,
or intimate partner violence as
normative and acceptable, that
reinforce negative stereotypes
about masculinity, or that objectify
and degrade women.
Further, failure to enforce existing
policies and laws against these
forms of violence may perpetuate
beliefs that these behaviors are
acceptable. It is important for all
sectors of society to work together
as part of any effort to end sexual
violence, stalking, and intimate
partner violence, both to change
norms, attitudes, and beliefs, as
well as support women and men in
rejecting violence.
Another strategy involves engaging
bystanders to change social norms
and intervene before violence
occurs. In many situations, there
are a variety of opportunities and
numerous people who can choose
to step forward and demonstrate
that violence will not be tolerated
within the community. For instance,
bystanders may speak out against
beliefs, attitudes, and behaviors
that support or condone sexual
violence, stalking, and intimate
partner violence − such as media
portrayals that glamorize violence
− and change the perceptions of
these social norms in their peer
groups, schools, and communities.
Ensure Appropriate
Response
An emphasis on primary preven-
tion is essential for reducing the
violence-related health burden in
the long term. However, secondary
and tertiary prevention programs
and services are also necessary for
mitigating the more immediate
consequences of violence. These
programs and services are valuable
for treating and reducing the
sequelae and severity of violence
and for intervening in the cycle of
violence. Sexual violence, stalking,
and intimate partner violence
are often repetitive and can recur
over long time periods. Several
strategic foci for the secondary
and tertiary prevention of violence
have emerged from the existing
knowledge base.

Develop a System of Care
to Ensure Healing and
Prevent The Recurrence of
Victimization
The effects of sexual violence,
stalking, and intimate partner
violence on survivors and commu-
nities are profound. For example,
survivors of sexual violence are
at a higher risk for a number
of physical and mental health
problems and other adverse life
events, including further victim-
ization. The health care system’s
response must be strengthened
and better coordinated for sexual
violence, stalking, and intimate
partner violence survivors to help
navigate the health care system
and access needed services and
resources in the short and long
term. For instance, more physicians
and other health care profes-
sionals need training on forensic
and patient care issues related to
sexual violence. The health care
response can be enhanced—and
survivors can be better served—if
more providers are equipped
with the specific knowledge and
skills necessary to provide good
forensic medical care, direction,
supervision, and leadership, as well
as provide respectful, sensitive
care and guidance to survivors.
Education and training should
be targeted specifically to stake-
holders who may be involved in
Sexual Assault Response Teams
(SARTs), as these first responders
set the tone for the victim’s experi-
ence in the criminal justice, health
care, and legal systems.
It is also important that health
professionals be alert to the signs
