Background: Stroke recovery is a dynamic process for stroke
survivors, and shorter lengths of stay in healthcare settings
shift the care of the survivors to family caregivers. The physical and mental sequelae after stroke and the family’s
response to this catastrophic event may have deleterious
effects on caregivers.
Objective: To examine the influence of stroke survivors’ motor
function, their memory and behavior changes, and the family conflict surrounding stroke recovery on the mental and
physical health of caregivers during the subacute recovery
period.
Methods: This cross-sectional, correlational study used baseline data from family caregivers (n ⫽ 132) and first-time
stroke survivors enrolled in a larger multisite study.
Results: The caregivers were primarily White (71%), female
(74%), college-educated (73%) spouses (80%) of survivors.
Most of the caregivers (66%) reported family conflict. The
caregivers from families with lower family functioning scores
reported worse mental health. The caregivers reported lower
mental health when they were caring for stroke survivors
with a combination of high memory/behavior changes and
low motor function (R² ⫽ .30). Family conflict appears to
exacerbate the impact of memory and behavior changes on
caregiver mental health. Higher caregiver education and no
major health problems were associated with better caregiver
physical health (R² ⫽ .36). Caregiver physical health was
not associated with family functioning or stroke survivor
memory and behavior changes.
Conclusions: These results indicate that memory and behavior changes of stroke survivors and family conflict surrounding stroke recovery are important considerations for assessment during the poststroke recovery period.

troke recovery is a dynamic process for stroke survivors, primary caregivers, and their families. In the
current healthcare environment, stroke survivors experience decreased lengths of stay in acute and rehabilitation
settings (Dobkin, 1995), which shifts a greater responsibility for care to the family early in the recovery process. The
emotional and tangible support that a family provides a
member with a serious illness is substantial, and the impact
on the family can be considerable (Ell, 1996). The influence of the stroke survivors’ specific problems and the family context on caregiver outcomes is unclear.
In general, the vast majority of disabled older adults in
a community rely on one or more family members who
provide some assistance. However, family caregivers of
stroke survivors often experience negative personal outcomes from caregiving (Bugge, Alexander, & Hagen, 1999;
Draper, Poulos, Cole, Poulos, & Ehrilich, 1992; Greveson,
Gray, French, & James, 1991; King, Shade-Zeldow, Carlson, Feldman, & Philip, 2002). Such negative consequences may be attributable to inadequate caregiver
knowledge and skills, lack of family support, or characteristics of the stroke survivor. Documented outcomes for
stroke family caregivers have shown significant mental distress at levels equivalent to that experienced by caregivers
of patients with Alzheimer’s disease (Clark & King, 2003;

Stroke survivors met extensive eligibility criteria for the
EXCITE trial (Winstein et al., 2003), which required them
to be 3 to 9 months post a first-time clinical cerebrovascular accident (ischemic or hemorrhagic), specific active
range-of-motion criteria for wrist movement, and a MiniMental State examination score of 24 or higher.
Research Setting and Design
This study was conducted at five sites across the United
States (six rehabilitation centers) that were locations for
EXCITE. Once a stroke survivor was enrolled in the
EXCITE trial, caregivers were asked about their willingness to participate in the study. Trained research assistants
collected data through in-person administration of questionnaires. In a nonrandom sample, factors associated
with caregiver outcomes were examined using a correlational cross-sectional design. Data reported are from baseline, and therefore not affected by the EXCITE intervention.
Instruments
Caregivers’ mental and physical health were measured
with the Medical Outcomes Study Short Form 36, Version
2 (SF-36v2) questionnaire (Ware, Kosinski, & Keller,
1994), a well-established measure for health status. The
SF-36v2 is a 36-item, self-report questionnaire from which
two primary components are calculated: a physical component scale (PCS) and a mental component scale (MCS).
The reliabilities of the PCS and MCS were acceptable, as
demonstrated by Cronbach’s alphas of .94 and .88, respectively. The PCS and MCS scores are standardized to the
general U.S. population, allowing for norm-based interpretation. Higher scores indicate better mental and physical
health.
Stroke survivors’ motor function was measured using
the Wolf Motor Function Test (WMFT), which uses a timebased method to evaluate upper extremity performance of
patients with stroke and traumatic brain injury (Wolf et al.,
2001). The WMFT involves strength and timed performance measures and quality of motor function. The average performance time (seconds) required for completion of
15 various tasks using the more affected arm was used to
quantify stroke survivors’ motor function. The WMFT has
demonstrated reliability and good clinometric properties
for the stroke population (Morris, Uswatte, Crago, Cook,
& Taub, 2001; Wolf et al., 2001).
The Memory and Behavior Problems Checklist
(MBPC) (Zarit & Zarit, 1990) was slightly modified to
reflect behaviors relevant to stroke and used to measure
stroke survivors’ memory and behavior changes. The 19item scale includes a wide array of memory and behavior
items. The frequency of memory and behavior problems is
rated on a Likert-type scale with a range of 0 (not having
occurred) to 3 (occurring daily). The MBPC internal consistency reliability coefficient was .73.
The 12-item General Family Functioning scale from the
McMaster Family Assessment Device was used to measure
general family functioning. This scale has established cutoff scores to enable interpretation of the data for family
functioning as “effective” or “ineffective” (Miller, Epstein,
Bishop, & Keitner, 1985). The Family Assessment Device,
recommended as an assessment measure for families of
stroke survivors, has had extensive psychometric testing
for adequate reliability and validity in a variety of populations (Epstein, Baldwin, & Bishop, 1983; King et al.,
2002). Higher scores indicate ineffective family functioning. The internal consistency reliability coefficient for the
General Family Functioning scale was .88.
Poststroke Influences on Caregivers’ Health 409
Nursing Research November/December 2004 Vol 53, No 6
The Family Caregiver Conflict Scale for Stroke is a 15item Likert-type scale developed to measure family conflict
surrounding stroke recovery. Content reliability and validity were established by Clark, Shields, Aycock, and Wolf
(2003). Participants indicate their agreement with the item
using a scale of 1 (not true at all) to 7 (very true). Higher
scores represent higher levels of conflict within a family.
The internal consistency reliability coefficient for the Family Caregiver Conflict Scale for Stroke was .94.
Demographic data for stroke survivors and caregivers,
such as age and education, were collected. Caregivers were
asked about major health problems, and their responses
were coded dichotomously as “no major health problem”
or “at least one major health problem.”
Statistical Analyses
Descriptive statistics were computed to characterize the
sample and describe major study variables. Before additional analysis was conducted, scatter plots and descriptive
statistics were used to examine the data for outliers and
distributional characteristics. The distributions of PCS and
MCS were slightly skewed. The assumptions of normality
for the error terms in the model and the constancy of their
variance were checked for each of the two dependent variables in the final model. It was determined that the error
distribution was normal, and that there was no deviation
from the assumption of constant error variance. The models also were examined using log transformations of PCS
and MCS, and the results were found to be similar. Therefore, the nontransformed results are reported.
In addition, the correlations between predictor variables were examined for multicollinearity. On the basis of
the conceptual model, hierarchical regression was used to
examine the association of stroke survivor motor and mental function and family conflict with caregiver mental and
physical health, with control used for caregiver characteristics and general family functioning. Data were missing on
one or more variables for a few caregivers or stroke survivors. Therefore, regression analyses were performed for
128 caregivers. Subsequently, all possible pairs of interaction effects were explored, and significant interactions
were retained in the model.
Results
At the time of the analysis, 183 stroke survivors were
enrolled in the EXCITE trial. Of these stroke survivors, 16
reported not having a caregiver. After 13 caregivers were
excluded, 154 caregivers eligible for participation remained,
19 of whom declined participation. Three caregivers were
inaccessible at the time of study enrollment. Consequently, a
total of 132 caregivers were enrolled in the study.
The characteristics of the caregivers are presented in

had sustained an ischemic (88%) rather than a hemorrhagic stroke (12%). Whereas 57% of the stroke survivors
had right hemisphere involvement, 43% had an infarct to
the left hemisphere.
On the average, caregivers reported healthy family
functioning, and showed lower scores on the General Family Functioning scale. However, 32% had scores above the
cutoff point (⬎2) for ineffective family functioning (Table
2). A score of 15 on the Family Caregiver Conflict Scale for
Stroke indicates no family conflict surrounding recovery.

An additional significant interaction between stroke
survivors’ memory and behavior changes and family conflict was obtained (Table 3 and Figure 3). Caregivers of
stroke survivors with low memory and behavior changes in
the presence of high family conflict levels reported mental
health scores similar to the scores of those caring for stroke
survivors with high memory and behavior problems regardless of the family conflict level. Associations with caregiver
physical health (Table 4) differed from associations with
caregiver mental health. The only variables associated with
caregiver physical health were caregiver education and
health problems. Caregivers with lower education and a
major health problem reported lower physical health.

Discussion
The results of the regression analysis are shown in
Table 3. Of the variables controlled in the first step, only
General Family Functioning was significant in the final
model, indicating that families with ineffective family functioning are associated with worse caregiver mental health.
There was a significant interaction of stroke survivors’
motor function and changes in memory and behavior, indicating that low motor function alone is not associated with
worse mental health, but that low motor function with
high memory and behavior changes is associated with
worse caregiver mental health. This interaction is illustrated in Figure 2. Low motor function with low memory
and behavior changes in stroke survivors resulted in caregiver mental health scores similar to those resulting from
high motor function and low changes in memory and
behavior in stroke survivors.
Both stroke survivor characteristics and family functioning
were associated with worse mental health of the caregiver,
but not with the caregiver’s physical health. The mean for
the PCS was similar and that for the MCS slightly lower
than reported general norms (50th percentile) (Ware et al.,
1994). During the stroke recovery period, the stress associated with rehabilitation may exacerbate problems within
families that already are functioning poorly. Even in cases
involving few stroke survivor memory and behavior
changes, family conflict is associated with decrements in
the mental health of caregivers. Some clinicians noted that
many stroke survivors participated in the EXCITE clinical
trial at the urging of the caregiver. The caregivers’ emotional investment of wanting the stroke survivor to participate in a therapy that could improve upper extremity
function may contribute to family conflict surrounding
stroke recovery. A randomized study found that a combination of education and counseling is effective for increasing stroke knowledge and reducing the decline in family

functioning (Evans, Matlock, Bishop, Stranahan, & Pederson, 1988). It is possible that the counseling reduced family conflict and improved the family’s ability to address
stroke survivor memory and behavior changes.
Caregivers within more effectively functioning family
systems are more likely to receive emotional and tangible
support. The caregiver’s perception that his or her family
can work together to deal with difficult situations, which
has been conceptualized as family hardiness (Clark, 2002),
may allow caregivers to share the responsibility of caring
for the stroke survivor and reduce their stress as caregivers.
The specific inclusion criteria for participation in the
constraint-induced therapy clinical trial required stroke
survivors to demonstrate at least 10° of extension at the
wrist and digits, 20° of extension at the elbow, and 45° of
flexion at the shoulder. However, the average motor function of stroke survivors in this subacute recovery period
was substantially slower than that reported in an earlier
study of chronic stroke survivors (Wolf et al., 2001). Also,
the frequency of memory and behavior changes among
stroke survivors was substantially less than the midpoint of
the scale, reflecting the relatively high functioning of stroke
survivors in EXCITE. Therefore, stroke survivors’ range of
physical ability was limited, and in a sample with a more
representative range of function, the results may have been
more conclusive.
In this study, caregiver characteristics such as gender
and relationship with care recipients were not associated
with caregiver mental health outcomes. No psychological
or family variables predicted the physical health of care-

givers. Only education and a major health problem were
associated with caregiver physical health. This may reflect
the difference in measurement among studies. The PCS
used in this study specifically reflects an individual’s ability
to accomplish physical activities rather than a general selfrating of physical health.
A limitation of this study is that the results cannot be
generalized beyond White, well-educated female caregivers, caregivers of cognitively impaired stroke survivors
(screened out if their Mini-Mental State Examination score
is less than 24), and caregivers undergoing treatment for
depression. Future studies should address these groups.
Another limitation of the study is its cross-sectional
design. It is difficult to separate current family functioning
in response to a crisis from the historical functioning of the
family. Although the findings indicate the importance of
the family dynamics in the context of stroke recovery, these
data cannot show whether this involves prestroke or poststroke functioning.
The interaction of stroke survivors’ memory and
behavior changes in motor function with caregivers’ mental health indicates that stroke survivors’ memory and
behavior changes are the most salient for caregivers’ mental health because the combination of poor motor function
and high memory and behavior changes has a significant
negative effect. This illustrates the powerful nature of
stroke survivors’ memory and behavior changes in their
effect on caregivers’ mental health and the need for healthcare providers always to evaluate these as well as stroke
survivor physical function. Addressing these changes will
benefit stroke survivors as well. ▼
