HOMVEE EXECUTIVE SUMMARY
Home Visiting Evidence of Effectiveness (HomVEE) was launched in fall 2009 to conduct a
thorough and transparent review of the home visiting research literature and provide an assessment
of the evidence of effectiveness for home visiting program models that serve families with pregnant
women and children from birth to age 5. The HomVEE review was conducted by Mathematica
Policy Research under the guidance of a Department of Health and Human Services (HHS)
interagency working group composed of representatives from:
• The Office of Planning, Research, and Evaluation (OPRE), Administration for Children
and Families (ACF)
• The Children’s Bureau, ACF
• The Centers for Disease Control and Prevention (CDC)
• The Health Resources and Services Administration (HRSA)
• The Office of the Assistant Secretary for Planning and Evaluation (ASPE)
The Patient Protection and Affordable Care Act established a Maternal, Infant, and Early
Childhood Home Visiting Program (MIECHV) that provides $1.5 billion over five years to states to
establish home visiting program models for at-risk pregnant women and children from birth to
age 5. The Act stipulates that 75 percent of the funds must be used for home visiting programs with
evidence of effectiveness based on rigorous evaluation research. The HomVEE review provides
information about which home visiting program models have evidence of effectiveness as required
by the legislation and defined by HHS, as well as detailed information about the samples of families
who participated in the research, the outcomes measured in each study, and the implementation
guidelines for each model.
This executive summary provides an overview of the HomVEE review process, a summary of
the review results, and a link to the HomVEE website for more detailed information.
Review Process
To conduct a thorough and transparent review of the home visiting research literature,
HomVEE performed seven main activities:
1. Conducted a broad literature search.
2. Screened studies for relevance.
3. Prioritized program models for the review.
4. Rated the quality of impact studies with eligible designs.
5. Assessed the evidence of effectiveness for each model.
6. Reviewed implementation information for each model.
7. Addressed potential conflicts of interest.
2
Literature Search
The HomVEE team conducted a broad search for literature on home visiting program models
serving pregnant women or families with children from birth to age 5.
1
1. Child health
The team limited the search
to research on models that used home visiting as the primary service delivery strategy and offered
home visits to most or all participants. Program models that provide services primarily in centers
with supplemental home visits were excluded. The search was also limited to research on home
visiting models that aimed to improve outcomes in at least one of the following eight domains
specified in the legislation:
2. Child development and school readiness
3. Family economic self-sufficiency
4. Linkages and referrals
5. Maternal health
6. Positive parenting practices
7. Reductions in child maltreatment
8. Reductions in juvenile delinquency, family violence, and crime
HomVEE’s literature search included four main activities:
1. Database Searches. The HomVEE team searched on relevant key words in a range of
research databases. Key words included terms related to the service delivery approach,
target population, and outcome domains of interest. The initial search was limited to
studies published since 1989; a more focused search on prioritized program models
included studies published since 1979 (see Prioritizing Programs below).
2. Website Searches. The HomVEE team used a custom Google search engine to search
more than 50 relevant government, university, research, and nonprofit websites for
unpublished reports and papers.
3. Call for Studies. In November 2009, HomVEE issued a call for studies and sent it to
approximately 40 relevant listservs for dissemination.
4. Review of Existing Literature Reviews and Meta-Analyses. The HomVEE team
checked search results against the bibliographies of recent literature reviews and meta-
analyses of home visiting models and added relevant missing citations to the search
results.
1
For the purposes of the MIECHV, home visiting program models have been defined as programs or initiatives in
which home visiting is a primary service delivery strategy and in which services are offered on a voluntary basis to
pregnant women, expectant fathers, and parents and caregivers of children from birth to kindergarten entry, targeting
participant outcomes that may include improved maternal and child health; prevention of child injuries, child abuse, or
maltreatment, and reduction of emergency department visits; improvement in school readiness and achievement;
reduction in crime or domestic violence; improvements in family economic self-sufficiency; improvements in the
coordination and referrals for other community resources and supports; or improvements in parenting skills related to
child development.
3
The literature search yielded approximately 8,200 unduplicated citations, including 150 articles
submitted through the HomVEE call for studies.
Screening Studies
The HomVEE review team screened all citations identified through the literature search for
relevance. The team screened out studies for the following reasons:
• Home visiting was not the primary service delivery strategy.
• The study did not use an eligible design (randomized controlled trial, quasi-experimental
design, or implementation study).
• The program did not include an eligible target population (pregnant women and families
with children from birth to age 5).
• The study did not examine any outcomes in the eight eligible outcome domains (child
development and school readiness; child health; family economic self-sufficiency;
linkages and referrals; maternal health; positive parenting practices; reductions in child
maltreatment; and reductions in juvenile delinquency, family violence, and crime).
• The study did not examine a named home visiting program model.
• The study was not published in English.
• The study was published before 1989 for the initial search or 1979 for the focused
search on prioritized program models.
Prioritizing Home Visiting Program Models for the Review
After screening, the initial search yielded studies on more than 250 home visiting program
models. To prioritize home visiting models for inclusion in the review, the HomVEE team created a
point system for ranking models. This point system was developed as a means of ranking models by
the extent of rigorous research evidence available on their effectiveness. Points were assigned to
models based on:
• The number and design of impact studies (three points for each randomized controlled
trial and two points for each quasi-experimental design)
• Sample sizes of impact studies (one point for each study with a sample size of 50 or
more)
HomVEE staff did not include models that had no information about implementation, were
implemented only in a developing-world context, or were no longer in operation and provided no
support for implementation.
To be useful to the home visiting field, the review should include information about the most
prevalent home visiting program models currently funded and implemented. Some frequently used
program models, however, may not have a sufficient number of causal studies to receive priority for
4
review. To ensure that the review included the most prevalent models, we compared the prioritized
list of models to an objective data source on the prevalence of implementation.
2
Through this process, the team prioritized 11 program models for the review. These models
were among those with the highest rankings based on HomVEE’s point system; models that ranked
below these 11 typically had only one or two impact studies of their effectiveness. Moreover, the
prioritized program models include the most widely used home visiting models and those that have
been most rigorously and extensively evaluated. They are:
We identified one
highly prevalent program model not on our prioritized list and added it in consultation with HHS.
1. Early Head Start–Home Visiting
2. Family Check-Up
3. Healthy Families America (HFA)
4. Healthy Start–Home Visiting
5. Healthy Steps
6. Home Instruction for Parents of Preschool Youngsters (HIPPY)
7. Nurse Family Partnership (NFP)
8. Parent-Child Home Program
9. Parents as Teachers (PAT)
10. Resource Mothers Program
11. SafeCare
HomVEE reviewed 162 impact studies and 122 implementation studies about these 11 models.
Rating the Quality of Impact Studies
For each of the 11 prioritized models, HomVEE reviewed impact studies with two types of
designs: randomized controlled trials and quasi-experimental designs
3
In brief, the high rating is reserved for random assignment studies with low attrition of sample
members and no reassignment of sample members after the original random assignment, and single
case and regression discontinuity designs that meet What Works Clearinghouse (WWC) design
(including matched
comparison group designs, single case designs, and regression discontinuity designs). Trained
reviewers assessed the research design and methodology of each study using a standard review
protocol. Each study was assigned a rating of high, moderate, or low to provide an indication of the
study design’s capacity to provide unbiased estimates of program impacts.

standards (Table 1).

Assessing Evidence of Effectiveness
The moderate rating applies to random assignment studies that, due to flaws in
the study design, execution, or analysis (for example, high sample attrition), do not meet all the
criteria for the high rating; matched comparison group designs that establish baseline equivalence on
selected measures; and single case and regression discontinuity designs that meet WWC design
standards with reservations. Studies that do not meet all of the criteria for either the high or
moderate ratings are assigned the low rating.
After completing all impact study reviews for a model, the HomVEE team evaluated the
evidence across all studies of the program models that received a high or moderate rating and
measured outcomes in at least one of the eligible outcome domains. To meet HHS’ criteria for an
“evidence-based early childhood home visiting service delivery model,” program models must meet
at least one of the following criteria:
• At least one high- or moderate-quality impact study of the model finds favorable,
statistically significant impacts in two or more of the eight outcome domains; or
• At least two high- or moderate-quality impact studies of the model using non-
overlapping analytic study samples find one or more favorable, statistically significant
impacts in the same domain.
In both cases, the impacts considered must either (1) be found for the full sample or (2) if
found for subgroups but not for the full sample, be replicated in the same domain in two or more
studies using non-overlapping analytic study samples. Additionally, following the legislation, if the
model meets the above criteria based on findings from randomized controlled trial(s) only, then one
or more favorable, statistically significant impacts must be sustained for at least one year after
program enrollment, and one or more favorable, statistically significant impacts must be reported in
a peer-reviewed journal.
5
In addition to assessing whether each model met the HHS criteria for an evidence-based early
childhood home visiting service delivery model, the HomVEE team examined and reported other
aspects of the evidence for each model based on all high- and moderate-quality studies available,
including the following:
• Quality of Outcome Measures. HomVEE classified outcome measures as primary if
data were collected through direct observation, direct assessment, or administrative
records; or if self-reported data were collected using a standardized (normed)
instrument. Other self-reported measures are classified as secondary.
• Duration of Impacts. HomVEE classified impacts as lasting if they were measured at
least one year after program services ended.

research (http://ies.ed.gov/ncee/wwc/). The WWC standard for attrition is transparent and statistically based, taking into account both overall
attrition (the percentage of study participants lost in the total study sample) and differential attrition (the differences in attrition rates between
treatment and control groups).

For ease of presentation, some of the criteria are described very broadly. Additional details about standards are available for single case designs

• Replication of Impacts. HomVEE classified impacts as replicated if favorable,
statistically significant impacts were shown in the same outcome domain in at least two
non-overlapping analytic study samples.
• Subgroup Findings. HomVEE reported subgroup findings if the findings were
replicated in the same outcome domain in at least two studies using different samples.
• Unfavorable or Ambiguous Impacts. In addition to favorable impacts, HomVEE
reported unfavorable or ambiguous, statistically significant impacts on full sample and
subgroup findings. While some outcomes are clearly unfavorable (such as an increase in
children’s behavior problems), others are ambiguous. For example, an increase in the
number of days mothers are hospitalized could indicate an increase in health problems
or increased access to needed health care due to participation in a home visiting
program.
• Evaluator Independence. HomVEE reported the funding source for each study and
whether any of the study authors were program model developers.
• Magnitude of Impacts. HomVEE reported effect sizes when possible, either those
calculated by the study authors or HomVEE computed findings.
Implementation Reviews
The HomVEE team collected information about implementation of the 11 prioritized models
from all impact studies with a high or moderate rating and from stand-alone implementation studies.
In addition, staff conducted internet searches to find implementation materials and guidance
available from home visiting program developers and national program offices. The HomVEE team
used this information to develop detailed implementation profiles for each model that include an
overview of the program model and information about prerequisites for implementation, materials
and forms, estimated costs, and program contact information. National program offices were invited
to review and comment on the profiles. The team also extracted information about implementation
experiences from the studies reviewed, including the characteristics of program participants, location
and setting, staffing and supervision, program model components, program model adaptations or
enhancements, dosage, fidelity measurement, costs, and lessons learned.
Addressing Conflicts of Interest
All members of the HomVEE team signed a conflict of interest statement in which they
declared any financial or personal connections to developers, studies, or products being reviewed
and confirmed their understanding of the process by which they must inform the project director if
such conflicts arise. The HomVEE review team’s project director assembled signed conflict of
interest forms for all project staff and subcontractors and monitored for possible conflicts over
time. If a team member was found to have a potential conflict of interest concerning a particular
home visiting model being reviewed, that team member was excluded from the review process for
the studies of that model. In addition, reviews for two program models previously evaluated by
Mathematica Policy Research were conducted by contracted reviewers who were not Mathematica
employees.

Summary of Review Results
The HomVEE review produced assessments of the evidence of effectiveness for each home
visiting model and outcome domain, as well as a description of each model’s implementation
guidelines. This section provides a summary of evidence of effectiveness by model and outcome
domain, a summary of implementation guidelines for program models with evidence of
effectiveness, and a discussion of gaps in the home visiting research literature.
Evidence of Effectiveness by Program Model
Overall, HomVEE identified impact studies with high or moderate ratings for seven home
visiting models: (1) Early Head Start-Home Visiting, (2) Family Check-Up, (3) Healthy Families
America (HFA), (4) Healthy Steps, (5) Home Instruction for Parents of Preschool Youngsters
(HIPPY), (6) Nurse Family Partnership (NFP), and (7) Parents as Teachers (PAT).
All seven of these models meet the HHS criteria for an evidence-based early childhood home
visiting service delivery model. All of them have at least one high- or moderate-quality study with at
least two favorable, statistically significant impacts in two different domains or two or more high- or
moderate-quality studies using non-overlapping analytic study samples with one or more statistically
significant, favorable impacts in the same domain.
Based on the available high- or moderate-quality studies, findings by program model are as
follows (Table 2):
• Early Head Start–Home Visiting had favorable impacts in three domains (child
development and school readiness, family economic self-sufficiency, and positive
parenting practices) and at least one favorable impact in all three domains was sustained
for at least one year after program inception and lasted for at least one year after
program completion. The available evidence indicated two unfavorable or ambiguous
impacts in the family economic self-sufficiency domain. The available evidence did not
indicate any of the findings were replicated in a second study sample.
• Family Check-Up had favorable impacts in three domains (child development and
school readiness, maternal health, and positive parenting practices) and impacts on
positive parenting practices were replicated in at least one other study sample. The
available evidence indicated that at least one favorable impact was sustained for at least
one year after program inception but did not indicate that any of the impacts lasted for
at least one year post program completion.
• Healthy Families America (HFA) had favorable impacts in seven domains (child
development and school readiness; child health; family economic self-sufficiency;
linkages and referrals; positive parenting practices; reductions in child maltreatment; and
reductions in juvenile delinquency, family violence, and crime). The findings in child
development and school readiness, child health, positive parenting practices, and
reductions in child maltreatment were replicated in at least one other study sample. The
available evidence indicated HFA had at least one unfavorable or ambiguous finding in
child health, family economic self-sufficiency, and linkages and referrals. The available
evidence indicated that at least one favorable impact in all seven domains was sustained
for at least one year after program inception but did not indicate any of the impacts
lasted for at least one year post program completion.

be interpreted with caution because there is subjectivity involved in interpreting some outcomes; for some outcomes, it is not always clear in
which direction it is desirable to move the outcome. Readers are encouraged to use the HomVEE website, specifically the reports by program
model and by outcome domain, to obtain more detail about unfavorable findings.

• Healthy Steps had favorable impacts in two domains (child health and positive
parenting practices). The available evidence indicated that at least one favorable impact
in positive parenting practices was sustained for at least one year after program
inception, but none of the impacts lasted for at least one year post program completion
or was replicated in a second study sample.
• Home Instruction for Parents of Preschool Youngsters (HIPPY) had favorable
impacts in two domains (child development and school readiness and positive parenting
practices), and both of these impacts were replicated in at least one other study sample.
The available evidence indicated that at least one favorable impact in both domains was
sustained for at least one year post program inception and at least one favorable impact
in child development and school readiness lasted for one year or more post program
completion.
• Nurse Family Partnership (NFP) had favorable impacts in seven domains (child
development and school readiness; child health; family economic self-sufficiency;
maternal health; positive parenting practices; reductions in child maltreatment; and
reductions in juvenile delinquency, family violence, and crime). At least one impact in all
seven domains was replicated in another study sample, was sustained at least one year
post program inception, and lasted for at least one year post completion. The evidence
indicated that NFP had unfavorable or ambiguous findings in five of the domains (child
development and school readiness; child health; linkages and referrals; positive
parenting practices; and reductions in juvenile delinquency, family violence, and crime).
• Parents as Teachers (PAT) had favorable impacts in two domains (child development
and school readiness and positive parenting practices). Favorable impacts in child
development and school readiness were replicated in at least one other study sample.
The evidence indicated that PAT had unfavorable or ambiguous findings in three
domains (child development and school readiness, family economic self-sufficiency, and
positive parenting practices). The evidence available indicated that favorable impacts in
child development and school readiness and positive parenting practices were sustained
for at least one year post program inception but did not indicate any of the impacts
lasted for at least one year post program completion.
In addition to the seven home visiting models described above, HomVEE reviewed four other
home visiting program models: (1) Healthy Start–Home Visiting, (2) Parent-Child Home Program,
(3) Resource Mothers Program, and (4) SafeCare. No high- or moderate-quality studies were
identified for these models, however, and consequently HomVEE was unable to assess their
effectiveness.
Evidence of Effectiveness by Outcome Domain
In seven of the eight outcome domains, at least one of the home visiting models had favorable
impacts on a primary measure (Table 3). None of the models, however, show impacts on reductions
in juvenile delinquency, family violence, and crime, using a primary outcome measure. All models
except Healthy Steps had favorable impacts on primary measures of child development and school
readiness and positive parenting practices. Nurse Family Partnership had the greatest breadth of
favorable findings, with favorable impacts on primary measures in six outcome domains.

Summary of Implementation Guidelines for Models with Evidence of Effectiveness
The MIECHV legislation specifies a number of program model implementation requirements.

6
Section 511(d)(3)(A)(i)(I). These variables include, “the model has been in existence for at least 3 years and is
research-based, grounded in relevant empirically-based knowledge, linked to program determined outcomes, associated
with a national organization or institution of higher education that has comprehensive home visitation program
standards that ensure high quality service delivery and continuous quality improvement…”
The review of information about implementation identified a number of requirements for
implementing home visiting models included in the review (Table 4). All programs in the HomVEE
review with evidence of effectiveness had been in existence for at least three years prior to the start
of the review, are associated with a national program office that provides training and support to
local program sites, and have minimum requirements for the frequency of home visits and for home
visitor supervision. In addition, most have pre-service training requirements, implementation fidelity
standards, a system for monitoring fidelity, and specified content and activities for the home visits.
Only three programs—Family Check-Up, Healthy Steps, and Nurse Family Partnership—have
specific educational requirements for home visitors.

Gaps in the Research
The HomVEE review identified several gaps in the existing research literature on home visiting
models that limit its usefulness for matching program models to community needs. First, research
evidence of program effectiveness is limited. As noted earlier, many models do not have high- or
moderate-quality studies of their effectiveness; thus, policymakers and program administrators
cannot determine whether those models are effective. Other models have only a few high- or
moderate-quality studies, indicating that additional research on those models may be needed.
Second, more evidence is needed about the effectiveness of home visiting models for different
types of families with a range of characteristics. Overall, the studies included in the HomVEE
review had fairly diverse study samples in terms of race/ethnicity and income. However, sample
sizes in these studies are not typically large enough to allow for analysis of findings separately by
subgroup. Moreover, HomVEE found little or no research on the effectiveness of home visiting
program models for families from American Indian tribes, immigrant families that have diverse
cultural backgrounds or may not speak English as a first language, or military families.
