Abstract—
This study examines the relative contributions of giving ver-
sus receiving support to longevity in a sample of older married adults.
Baseline indicators of giving and receiving support were used to predict
mortality status over a 5-year period in the Changing Lives of Older
Couples sample. Results from logistic regression analyses indicated that
mortality was significantly reduced for individuals who reported provid-
ing instrumental support to friends, relatives, and neighbors, and indi-
viduals who reported providing emotional support to their spouse.
Receiving support had no effect on mortality once giving support was
taken into consideration. This pattern of findings was obtained after
controlling for demographic, personality, health, mental health, and
marital-relationship variables. These results have implications for un-
derstanding how social contact influences health and longevity.
As demographic shifts have produced a relatively more aged popula-
tion, factors that influence longevity have taken on increased promi-
nence. The documented health benefits of social support may offer a
promising avenue for reducing mortality among older adults. Indeed,
there is a robust association between social contact and health and well-
being (House, Landis, & Umberson, 1988). However, it is not clear that
receiving support accounts for these benefits (House et al., 1988). Tests
of the social-support hypothesis—that receiving support improves
health and well-being—have provided somewhat inconsistent results
(Kahn, 1994), demonstrating in some instances that receiving support is
harmful (e.g., S.L. Brown & Vinokur, in press; Hays, Saunders, Flint,
Kaplan, & Blazer, 1997; Seeman, Bruce, & McAvay, 1996). In fact, a
meta-analysis of the link between social support and health outcomes
produced negligible findings, leading the study’s authors to conclude
that the “small amounts of shared variance [between receiving support
and health outcomes] may not be considered significant nor generaliz-
able” (Smith, Fernengel, Holcroft, Gerald, & Marien, 1994, p. 352).
Conceptually, it is not clear that receiving social support will always
be beneficial. For example, depending on other people for support can
cause guilt and anxiety (Lu & Argyle, 1992). And feeling like a burden
to others who presumably provide support is associated with increased
suicidal tendencies, even after controlling for depression (R.M. Brown,
Dahlen, Mills, Rick, & Biblarz, 1999; de Catanzaro, 1986). The correla-
tion of social support with dependence may help to explain why studies
have failed to consistently confirm the social-support hypothesis.
Furthermore, the benefits of social contact may extend beyond re-
ceived support to include other aspects of the interpersonal relation-

ship that may protect health and increase longevity—for example,
giving support to others. However, with few exceptions (e.g., Liang,
Krause, & Bennett, 2001), social-support studies rarely assess whether
there are benefits from providing support to others. Some measures of
social support do seem to tap giving—perhaps inadvertently—yet the
benefits are often attributed to receiving support or sometimes attrib-
uted to reciprocated support. For example, a nationwide survey of
older peoples’ support networks measured social support by a combi-
nation of what was received and what was provided to others (Anto-
nucci, 1985). Implicit in this assessment is the recognition that
receiving social support is likely to be correlated with other aspects of
close relationships, including the extent to which individuals give to
one another. Thus, some of the benefits of social contact, traditionally
attributed to receiving support, or to reciprocated support (e.g., Anto-
nucci, Fuhrer, & Jackson, 1991), may instead be due to the benefits of
giving support.
THE BENEFITS OF PROVIDING SUPPORT
TO OTHERS
There are both theoretical and empirical reasons to hypothesize
that giving support may promote longevity. For example, kin-selection
theory (Hamilton, 1964a, 1964b) and reciprocal-altruism theory (Triv-
ers, 1971) suggest that human reproductive success was contingent
upon the ability to give resources to relationship partners. Social
bonds (S.L. Brown, 1999) and emotional commitment (Nesse, 2001)
have been theorized to promote high-cost giving. The resulting contri-
bution made to relationship partners is theorized to trigger a desire for
self-preservation on the part of the giver, enabling prolonged invest-
ment in kin (de Catanzaro, 1986) and reciprocal altruists.
Although few studies have explicitly examined whether helping
others increases longevity, sociologists note the ubiquity of giving to
others (Rossi, 2001), and studies show that individuals derive benefits
from helping others, such as reduced distress (Cialdini, Darby, & Vin-
cent, 1973; Midlarsky, 1991) and improved health (Schwartz &
Sendor, 2000). Moreover, volunteering has beneficial effects for vol-
unteers, including improved physical and mental health (Omoto &
Synder, 1995; Wilson & Musick, 1999). Even perceptions that are
likely to be associated with giving, such as a sense of meaning, pur-
pose, belonging, and mattering, have been shown to increase happi-
ness and decrease depression (e.g., Taylor & Turner, 2000; see Batson,
1998, for a review).
THE PRESENT STUDY
Using data from the Changing Lives of Older Couples (CLOC)
sample, we addressed two questions: (a) Do the benefits of providing
social support account for some or all of the benefits of social contact

that are traditionally interpreted as due to support received from oth-
ers? (b) Does receiving support influence mortality once giving sup-
port and dependence are controlled?
Traditionally, social support has been defined in numerous ways,
leading some authors to conclude that measurement issues are a
source of contradictory findings (e.g., Smerglia, Miller, & Kort-Butler,
1999). For the purpose of the present study, we focused our analyses
on items for which our measures of giving and receiving tapped simi-
lar domains of support. Similar domains of support were measured for
the exchange of emotional support between spouses and the exchange
of instrumental support with individuals other than one’s spouse.
House (1981) suggested that these two domains of support—emo-
tional and instrumental—represent two of the functions of interper-
sonal transactions.
To isolate the unique effects of giving and receiving social support
on mortality, it was important to control for factors that may influence
any of these variables, including age, gender, perceived health, health
behaviors, mental health, socioeconomic status, and some individual
difference variables (personality traits). Controlling for these variables
helped to increase our confidence that any beneficial effect of giving
we observed was not due to enhanced mental or physical robustness of
the giver. We also examined variables associated with relationship
phenomena that could influence giving support, receiving support, and
dependence; these variables included perceived equity (the perception
that one receives the same amount as one provides to the relationship
partner) and relationship satisfaction. Responses at baseline were used
to predict mortality status over the ensuing 5-year period of the study.
METHOD
Sample
The CLOC study is a prospective study of a two-stage area proba-
bility sample of 1,532 married individuals from the Detroit Standard
Metropolitan Statistical Area. The husband in each household was 65
years of age or older (see Carr et al., 2000, for a complete report). Of
those individuals who were selected for participation in the CLOC
study, 65% agreed to participate, a response rate consistent with re-
sponse rates in other studies in the Detroit area (Carr et al., 2000).
More than one half of the sample (n 846) consisted of married cou-
ples for whom mortality data on both members were available. These
423 married couples were the respondents in the present study.
1
Base-
line measures were administered in face-to-face interviews, conducted
over an 11-month period in 1987 and 1988. Of the subsample of 846
respondents, 134 died over the 5-year course of the study.
Mortality Data
Mortality was monitored over a 5-year period by checking daily
obituaries in three Detroit-area newspapers and monthly death-record
tapes provided by the State of Michigan. Mortality status was indi-
cated with a dichotomous variable (1 deceased, 0 alive).
Baseline Measures
Instrumental support
Giving instrumental support to others
, GISO, was measured by
four survey questions that asked respondents whether they had given
instrumental support to friends, neighbors, and relatives other than
their spouse in the past 12 months. Respondents indicated (yes/no)
whether they helped with (a) transportation, errands, shopping; (b)
housework; (c) child care; and (d) other tasks. Respondents were in-
structed to say “yes” to any of these questions only if they did not live
in the same household with the recipient of support and they did not
receive monetary compensation. Responses were coded so that a “0”
indicated a “no” response to all four items, and a “1” indicated a “yes”
response to at least one item.
Receiving instrumental support from others, RISO, was assessed
by a single item: “If you and your husband [wife] needed extra help
with general housework or home maintenance, how much could you
count on friends or family members to help you?” Responses were
coded on a 4-point scale.
2
Emotional support
Giving and receiving emotional support was assessed with items
from the Dyadic Adjustment Scale (Spanier, 1976).
Giving emotional
support to a spouse, GESS, was assessed using two items that asked
participants whether they made their spouse feel loved and cared for
and whether they were willing to listen if their spouse needed to talk
( .51). Rankin-Esquer, Deeter, and Taylor (2000) reviewed evi-
dence to suggest that the benefits of receiving emotional support from
a spouse come from both feeling emotionally supported by a spouse
and feeling free to have an open discussion with one’s spouse. The
two-item measure of receiving emotional support from a spouse,
RESS ( .66), was identical to GESS with the exception that partic-
ipants were asked whether their spouse made them feel loved and
cared for, and whether their spouse was willing to listen if they needed
to talk. Responses were coded on a 5-point scale.
3
Control variables
To control for the possibility that any beneficial effects of giving
support are due to a type of mental or physical robustness that under-
lies both giving and mortality risk, we measured a variety of demo-
graphic, health, and individual difference variables. (See Appendix A
for a description of the health, mental health, and personality variables
used.) Both age and gender (1 male, 2 female) were controlled
for in each analysis to take into account the possibilities that (a) older
people give less and are more likely to die than younger people and (b)
females give more and are less likely to die than males.
To isolate the unique effects of giving and receiving support, above
and beyond other known relationship influences on health, we in-
cluded measures of social contact and dependence. Social contact was
assessed with the mean of the following three questions: “In a typical
1. For the entire sample, spousal mortality, rather than respondent mortal-
ity, was tracked, so respondent mortality could be obtained only if both mem-
bers of a couple participated in the study.
2. All response options were coded so that higher values indicated higher
levels of the measured variable.
3. Unless otherwise stated, scale composites were formed by taking the
mean of the items.

week, about how many times do you talk on the phone with friends,
neighbors, or relatives?” “How often do you get together with friends,
neighbors, or relatives and do things like go out together or visit in
each other’s homes?” and “How often do you go out socially, by your-
self, or with people other than your husband [wife]?” Scores were
standardized so that higher values indicated greater social contact (
.51). Dependence on the spouse was coded on a 4-point scale and was
measured with three items asking participants whether losing their
spouse would make them feel lost, be terrifying, or be the worst thing
that could happen to them ( .82).
Additional relationship variables
We measured additional aspects of the marital relationship in order
to examine alternative explanations for any effects of giving and re-
ceiving emotional support. Specifically, we used items from the Dy-
adic Adjustment Scale (Spanier, 1976) to assess
equity
(the absolute
value of the difference between an individual’s ratings of perceived
emotional support received from the partner and perceived emotional
support provided to the partner; higher values indicated greater dis-
crepancy) and marital satisfaction (one item).
Additional measures of receiving and giving support
To consider the possibility that any observed benefits of giving or
receiving support were an artifact of the chosen measures, we in-
cluded all of the remaining support measures from the CLOC data set
(Appendix B).
RESULTS
We examined our hypotheses using the 846 persons for whom
mortality data were available. Because this sample included the re-
sponses of both members of a couple, we computed the intraclass cor-
relation (ICC) for the couple-level effect on mortality. We first created
a variable that grouped individual participants by couple (n 423).
We next constructed a two-level hierarchical model (Level 1 estimated
variation in mortality at the individual-participant level, Level 2 esti-
mated variation at the couple level) using RIGLS (restricted iterative
generalized least squares) estimation for binomial models (MLwiN
ver. 1.1, Multilevel Models Project, Institute of Education, London,
2000). A significant ICC could be interpreted as indicating that the
death of one partner was significantly related to an increase or de-
crease in the probability of the other partner dying (within the study
period). Results of this procedure indicated that there was no couple-
level effect on mortality (ICC .00, n.s.). Thus, for all analyses, we
treated each member of a couple as an independent source of data.
Giving Support, Receiving Support, and Social Contact
Table 1 presents a correlation matrix of the focal social-support
measures. Receiving and giving were significantly and strongly corre-
lated for measures of emotional support exchanged between spouses
(r .58, p .001), and weakly correlated for measures of instrumen-
tal support exchanged with others (r .09, p .01).
To examine whether giving instrumental support reduced risk of
mortality, we ran a hierarchical logistic regression procedure. Results
of this analysis are displayed in Figure 1, and also presented in Table
2. Step 1 of this analysis regressed mortality status on social contact,
age, and gender. The results were consistent with previous research in
indicating that social contact reduced the risk of mortality (b
0.21, p .05). To examine whether giving versus receiving support
accounted for this effect, we entered GISO and RISO simultaneously
in the second step. Results at this step indicated that mortality risk was
decreased by GISO (b 0.85, p .001) but marginally increased
by RISO (b 0.17, p .10). Social contact was no longer significant
at this step (b 0.13, n.s.).
Because individuals in poor health may have difficulty providing
others with instrumental support, functional health status, satisfaction
with health, health behaviors, and mental health variables were added
to the model in order to control for the alternative possibility that indi-
viduals who give support to others live longer because they are more
mentally and physically robust than those who do not give support.
Results at this step indicated that after controlling for these measures
of health, the effect of GISO was reduced, but GISO was still signifi-
cantly related to mortality (b 0.56, p .01). In fact, GISO exerted
a beneficial effect on mortality even after controlling for interviewer
ratings of health, income and education level, self-reports of feeling vul-
nerable to stress, dispositional influences on mortality, and personality
influences on mortality. After all control variables were held constant,
GISO significantly decreased mortality risk (b 0.54, p .05), and
RISO marginally increased mortality risk (b 0.23, p .10).
These results support the hypothesis that giving support accounts
for some of the benefits of social contact. However, our findings are
based on the use of different measures to operationalize giving and re-
ceiving support. That is, the GISO variable measured support that was
actually provided to other people (i.e., enacted support), whereas the
RISO variable assessed whether others could be depended upon to
provide support (i.e., available support).
4
Furthermore, it is not clear
whether the adverse effect of RISO was due to received support or to
the covariation of received support with dependence. In order to con-
trol for the difference between the giving and receiving measures, as
well as the potentially adverse effect of dependence, we examined the
exchange of emotional support between spouses. This domain of sup-
port offered virtually identical giving and receiving measures, and in-
cluded measures of dependence.

Analyses With Identical Measures of Giving and
Receiving Support
To clarify the role of receiving support on mortality, we ran a hier-
archical logistic regression procedure in which RESS was entered in
Step 1, along with age and gender. As can be seen in Figure 2, there
was no significant effect of RESS on the risk of mortality (b 0.17,
n.s.). However, after controlling for the effect of dependence in Step 2,
the effect of RESS became a significant predictor of reduced mortality
risk (b 0.23, p .05). Thus, the results of Step 2 replicated the
beneficial effect of receiving support sometimes found in the literature—
but only after the adverse effect of dependence was held constant.
To compare the relative benefits of receiving versus giving support
using identical measures, we entered GESS on the third step of this
analysis. As shown in Figure 2, the unique effect of GESS accounted
for a significant decrease in mortality risk (b 0.36, p .05), and
rendered the effect of RESS nonsignificant (b 0.05, n.s.). In order
to examine whether GESS remained beneficial after controlling for
GISO and the cumulative effect of all of the control variables, we en-
tered GESS into the hierarchical regression model presented in Table
2 (Step 5). Results of this analysis demonstrated that both GESS (b
0.51, p .01) and GISO (b 0.50, p .05) made a unique, sig-
nificant contribution to reducing mortality risk, above and beyond that
of the control variables. Thus, giving to one’s spouse (GESS) and giv-
ing to friends, relatives, and neighbors (GISO) both appear to exert an
independent influence on the reduction in risk of mortality.
Finally, we examined two additional relationship factors that may
be related to giving support—equity and marital satisfaction. We first
added marital satisfaction to the overall model (shown in Table 2 and
Fig. 1); it was not a significant predictor of mortality (b 0.15,
n.s.), nor did it affect the strength of any of the other predictors. We
ran a similar model for equity, without GESS and RESS. Equity did
not predict mortality (b 0.20, n.s.).
Additional Measures of Receiving and Giving
Because the CLOC data included additional measures of giving and re-
ceiving, it was possible to determine whether our pattern of results was
simply an artifact of the measures chosen. To examine this possibility, we
correlated mortality status with each of the giving and receiving measures
available in the CLOC data set. In addition, the composites for giving sup-
port were broken down into single items and correlated independently with
mortality status. As shown in Table 3, only 1 of the 10 different receiving
measures significantly reduced mortality risk5; 1 receiving measure signifi-

5. Substituting the only beneficial receiving measure in the overall regres-
sion model presented in Table 2 did not alter our pattern of findings.

cantly increased mortality risk. In contrast, all 4 of the different giving mea-
sures significantly reduced mortality risk. When the composites for giving
support were broken down, 4 of the 6 items were significantly correlated
with decreased mortality risk, including the only item that assessed avail-
able, rather than enacted, support. Taken together, these findings strongly
suggest that giving support, rather than receiving support, accounts for the
benefits of social contact, across different domains of support, different tar-
gets of support, and different structural features of support.
DISCUSSION
In this study, older adults who reported giving support to others
had a reduced risk of mortality. The provision of support was corre-
lated with reduced mortality in all analyses, whether giving support
was operationalized as instrumental support provided to neighbors,
friends, and relatives or as emotional support provided to a spouse. It
is important to note that our analyses controlled for a wide range of
demographic, personality, and health variables that might have ac-
counted for these findings. Thus, these results add to a small but grow-
ing body of research that documents the health benefits of providing
support to others (McClellan, Stanwyck, & Anson, 1993; Midlarsky,
1991; Schwartz & Sendor, 2000).
We also found that the relationship between receiving social sup-
port and mortality changed as a function of whether dependence and
giving support were taken into consideration. Receiving emotional
support (RESS) appeared to reduce the risk of mortality when depen-

dence but not giving emotional support was controlled. Receiving
instrumental support from others appeared to increase the risk of
mortality when giving support, but not dependence, was controlled.
Taken together, these findings may help to explain why tests of the so-
cial-support hypothesis have produced contradictory results. If the
benefits of social contact are mostly associated with giving, then mea-
sures that assess receiving alone may be imprecise, producing equivo-
cal results.
Although we have identified no single mediator of the link between
giving support and mortality—one that could be informative about the
process underlying the beneficial effects of giving support—many so-
cial psychological studies show that helping others increases positive
emotion (e.g., Cialdini & Kenrick, 1976). Positive emotions, in turn,
have been demonstrated to speed the cardiovascular recovery from the
aftereffects of negative emotion (Fredrickson, Mancuso, Branigan, &
Tugade, 2000). Thus, helping may promote health through its associa-
tion with factors, such as positive emotion, that reduce the deleterious
effects of negative emotion. Research is currently under way to exam-
ine this possibility.
More broadly, a link between giving and health supports the possi-
bility that the benefits of social contact were shaped, in part, by the
evolutionary advantages of helping others. Older adults may have
been able to increase their inclusive fitness (the reproductive success
of individuals who shared their genes) by staying alive and prolonging
the amount of time they could contribute to family members (de Cat-
anzaro, 1986). Of course, this possibility relies on the assumption that
a motivation for self-preservation can influence mortality. In fact,
there is evidence to suggest that individuals with a “fighting spirit”
survive longer with cancer than individuals who feel helpless or less
optimistic about their chance of survival (Greer, Morris, & Pettingale,
1994).
Limitations and Directions for Future Research
Although the prospective, longitudinal design of this study is very
strong, given the outcome of interest, alternative explanations for
these findings remain viable. It may be, for example, that giving sup-
port is a better measure of health than receiving support, or that indi-
viduals who have the resources and motivation to give are also more
robust than those who do not, or that an abundance of resources pro-
motes longevity and makes it easier to give. However, the beneficial
effects of giving support were observed after controlling for the effects
of age, functional health, satisfaction with health, health behaviors,
mental health, interviewer ratings of health, socioeconomic status, and
vulnerability to stress. Moreover, two distinct types of giving—GESS
and GISO—contributed simultaneously to longevity. This means that
a third variable correlated with one measure of giving—such as ro-
bustness of one’s health—would have been held constant in a model
that simultaneously tested the effect of the other giving measure.
Thus, it is unlikely that the same alternative explanation can account
for both effects of giving support. Of course, given the correlational
nature of the study design, the regression methods used to disentangle

It would be premature, on the basis of a single study, to conclude
that giving support accounts for the traditional effects of receiving so-
cial support found in the literature (to our knowledge, no other studies
have advanced this hypothesis). Nevertheless, the results of the
present study should be considered a strong argument for the inclusion
of measures of giving support in future studies of social support. Per-
haps more important, our results corroborate the suggestion by House
and his colleagues (1988) that researchers should be cautious of as-
suming that the benefits of social contact reside in the supportive qual-
ity of the relationship. Thus, whether or not mortality risk is a function
of giving support, our results highlight the continued need for further
research to seriously examine the fundamental assumption guiding the
study of social support.
Conclusion
Giving support may be an important component of interpersonal
relationships that has considerable value to health and well-being. It
may not be a coincidence that mortality and morbidity studies inad-
vertently assess giving or manipulate giving (e.g., taking care of a
plant; Rodin & Langer, 1977) to operationalize variables of interest
such as receiving social support or locus of control. If giving, rather
than receiving, promotes longevity, then interventions that are cur-
rently designed to help people feel supported may need to be rede-
signed so that the emphasis is on what people do to help others. The
possibility that giving support accounts for some of the benefits of so-
cial contact is a new question that awaits future research.

these alternatives do not give the confidence that would be achieved
by an experimental design. Nonetheless, longitudinal prospective
studies like the one described here are important precursors to even-

APPENDIX A: CONTROL VARIABLES
Physical health was measured with two scales assessing (a) satisfaction
with health ( .84) and (b) functional health. Satisfaction with health was a
three-item scale measuring the extent to which participants rated their health as
excellent, good, fair, or poor; the extent to which they thought their health lim-
ited their daily activities; and the extent to which they were satisfied with their
health. The functional health index measured the extent to which participants’
health prevented them from leaving their bed or chair (yes/no) or interfered
with a variety of tasks, including walking, climbing stairs, bathing, and house-
work (yes/no). Functional impairment levels were as follows: 1 most severe
(respondents who were currently in bed or a chair, who had a lot of difficulty
bathing or could not bathe, or both); 2 moderately severe (respondents who
had a lot of difficulty climbing stairs or could not climb stairs); 3 least severe
(respondents who had difficulty doing heavy work, but were not in one of the
more severe categories); 4 no functional impairment (answered “no” to all
questions).
To control for the possibility that there are aspects of physical robustness
that are not partialed out with self-report measures, we also included inter-
viewer ratings of the physical health of the participant, from 1, excellent, to 4,
poor. Health behaviors included measures of smoking (number of cigarettes
per day), drinking (number of drinks in the past month), and exercise (fre-
quency of taking walks or other form of exercise). Depression ( .83) was
measured with a short form of the Center for Epidemiologic Studies Depres-
sion (CES-D) scale (Radloff, 1977). Subjective well-being ( .79) was as-
sessed with a subset of five items developed by Bradburn (1969) to assess how
often (1 hardly ever, 2 some of the time, 3 most of the time) participants
experienced positive feelings such as joy and contentment.
Individual difference variables included modified scales from the NEO
Five-Factor Personality Inventory (i.e., Extraversion, .53; Agreeableness,
.62; Conscientiousness, .73; Openness to Experience, .51; and
Neuroticism, .70; Costa & McCrae, 1992), as well as measures of self-
esteem ( .72; Rosenberg, 1962), locus of control (internal .71; external
.68; Levenson, 1973), interpersonal dependency ( .66), and autonomy
( .75; Hirschfield et al., 1989). We also measured vulnerability to stress
( .60) with items assessing the degree to which participants felt they could
handle themselves in a crisis.
APPENDIX B: ADDITIONAL MEASURES OF
GIVING AND RECEIVING
The following items were used to measure additional forms of receiving:
the availability of others, besides a spouse, to provide caretaking for a serious
illness; the availability of anyone, including a spouse, to provide intimacy; the
number of individuals, including a spouse, who provide intimacy; a composite
of enacted and available emotional support from others besides a spouse (simi-
lar to RESS); dependence on a spouse for receiving help with household
chores (enacted support); spouse’s help with household repairs (enacted sup-
port); spouse’s help with paying bills (enacted support); and spouse’s help with
financial or legal advice (enacted support). The following items were available
to measure additional forms of giving: number of hours spent helping others
with errands (including transportation and shopping), child care, housework, or
other needs without compensation, and satisfaction of providing help without
compensation to others, besides a spouse.
