A Longitudinal Investigation of the Association Between Stroke and Loneliness.

OBJECTIVES: The present research examined associations between stroke and long-term trajectories of loneliness. METHODS: We conducted secondary analyses in 3 large representative panel studies of adults 50 years and older in the United States, Europe, and Israel: the English Longitudinal Study of Aging (ELSA; analytic N = 14,992); the Survey of Health, Aging, and Retirement in Europe (SHARE; analytic N = 103,782); and the Health and Retirement Study (HRS; analytic N = 22,179). Within each sample, we used discontinuous growth curve modeling to estimate loneliness trajectories across adulthood and the impact of stroke on loneliness trajectories. RESULTS: Across all 3 samples, participants who experienced stroke reported higher levels of loneliness relative to participants who did not experience stroke. In ELSA and HRS (but not SHARE), loneliness levels were higher after stroke onset relative to before stroke onset. DISCUSSION: This research adds to a growing body of evidence demonstrating elevated loneliness among stroke survivors and highlights the need for interventions to increase social connectedness after stroke.

Mental Health Mediators for Subjective, Not Objective, Cognition, and Community Participation Poststroke.

Previous studies have stated that both objective and subjective cognitive abilities and mental health symptoms are associated with community participation poststroke. However, there is a need to understand the direct and indirect associations among these variables in persons with stroke. The objective of this study was to investigate whether mental health symptoms mediate the associations of subjective and objective cognitive abilities with community participation poststroke. We built regression-based mediation models with 74 participants with mild to moderate stroke. Independent variables were objective and subjective cognitive abilities. The dependent variable was community participation. Mediators were mental health symptoms including depression, apathy, and anxiety. The results indicated that depression (b = .093), apathy (b = .134), and anxiety (b = .116) fully mediated the association between subjective cognitive ability (p < .05), but not objective cognitive ability (p > .05), and community participation poststroke. Our findings suggest that poor subjective cognitive ability combined with mental health symptoms should be addressed together to promote community participation poststroke.

Mental Health Mediators for Subjective, Not Objective, Cognition, and Community Participation PoststrokeResearchers and clinicians have used both objective and subjective tools to evaluate cognitive abilities including memory, attention, and thinking. Objective cognitive ability indicates the level of cognitive ability measured using an objective tool such as pen and paper tests while subjective cognitive ability refers to self-perceived cognitive ability indicated via self-report questionnaires. Previous studies have shown that both objective and subjective cognitive abilities and mental health symptoms (depression, anxiety, and apathy) are associated with community participation in persons with stroke. However, there is a need to understand the direct and indirect associations among objective and subjective cognitive abilities, mental health symptoms, and community participation. In this context, we investigated if mental health symptoms mediated the associations of subjective and objective cognitive ability with community participation poststroke. Our results suggest that mental health symptoms fully mediated the associations between subjective cognitive ability and community participation but not the associations between objective cognitive ability and community participation poststroke. Our findings propose that rehabilitation and occupational therapy professionals should carefully monitor subjective cognitive problems with special attention to persons with poststroke depression, apathy, and anxiety to increase community participation poststroke.

Social participation mediates the relationship between self-efficacy and loneliness among people with stroke during COVID-19: a cross-sectional study.

BACKGROUND: People post-stroke experience increased loneliness, compared to their healthy peers and loneliness may have increased during COVID due to social distancing. How social distancing affected loneliness among people after stroke is unknown. Bandura's self-efficacy theory suggests that self-efficacy may be a critical component affecting individuals' emotions, behaviors, attitudes, and interpretation of everyday situations. Additionally, previous studies indicate that self-efficacy is associated with both loneliness and social participation. This study investigates relationships among self-efficacy, social participation, and loneliness in people with stroke. OBJECTIVES: Determine how social participation affects the relationship between self-efficacy and loneliness in people with stroke during the COVID-19 pandemic. METHODS: 44 participants were community-dwelling individuals, ≥ 6 months post-stroke who participated in a 2-hour phone interview. A regression-based mediation analysis was conducted using these measures: Participation Strategies Self-Efficacy Scale, Activity Card Sort for social participation, and UCLA Loneliness Scale for loneliness. RESULTS: The total effect of self-efficacy on loneliness was significant (b = -0.36, p = .01). However, social participation fully mediated the relationship between self-efficacy and loneliness (indirect effect, b = -0.11, 95% CI [-0.24, -0.01]; direct effect, b = -0.25, 95% CI [-0.03, 0]). CONCLUSIONS: Self-efficacy is associated with both social participation and loneliness in people with stroke in this cross-sectional study. Mediation analysis findings suggest that interventions focused on increasing social participation may prevent or potentially alleviate loneliness in people with stroke who have low self-efficacy.

The mediating effect of anxiety on the association between residual neurological impairment and post-stroke participation among persons with and without post-stroke depression.

Previous research has reported that residual neurological impairment and emotional factors play a role in regaining successful participation post-stroke. The objective of this study was to investigate the mediating impact of anxiety on the association between residual neurological impairment and participation in survivors with and without post-stroke depressive symptoms. Participants (N = 79) were classified into 2 categories, those with post-stroke depressive symptoms (N = 40) and those without post-stroke depressive symptoms (N = 39). Variables measured in this study: residual neurological impairment (NIH Stroke Scale Score), participation (Reintegration to Normal Living Index), depressive symptoms (Patient Health Questionnaire-9), and trait anxiety (State-Trait Anxiety Inventory). A regression-based mediation analysis was conducted for each group of participants. The majority of participants had some level of anxiety. Residual neurological impairment predicted participation in stroke survivors both with (ß = -.45, p = .003) and without (ß = -.45, p = .004) post-stroke depressive symptoms. Anxiety mediated this relationship in participants with depressive symptoms (ß = -.19, 95% CI = -.361 ∼ -.049), but not in participants without depressive symptoms (ß = -.18, 95% CI = -.014 ∼ .378). Depressive and anxious symptoms should both be addressed to best facilitate participation by stroke survivors.

Identifying emotional contributors to participation post-stroke.

BACKGROUND: Participation in daily activities is the ultimate goal of stroke rehabilitation. Emotional factors have been considered as contributors to participation, but associations between emotional factors and participation post-stroke have not been fully explored. OBJECTIVE: To investigate the extent to which emotional factors contribute to participation post-stroke. METHODS: 73 participants were included. Three participation outcomes were used as dependent variables in three models: (1) Stroke Impact Scale (SIS) Participation/Role Function, (2) Activity Card Sort (ACS), and (3) Reintegration to Normal Living (RNL). Main independent variables were six emotional factors: SIS Emotion Function (General emotion), Visual Analog Mood Scale energetic and happy subscales, Patient Health Questionnaire-9 (Depression), State-Trait Anxiety Inventory-Trait Anxiety Scale, and Apathy Evaluation Scale. Covariates of stroke severity and social support were included. RESULTS: Model 1 showed stroke severity (ß = -0.300) and depression (ß = -0.268) were significant contributors to SIS Participation/Role Function (R2 = 0.368, p < .05). Model 2 indicated that happiness (ß = 0.284) and apathy (ß = -0.330) significantly contributed to ACS total activity retention (R2 = 0.247, p < .05). Model 3 revealed that anxiety (ß = -0.348), apathy (ß = -0.303), stroke severity (ß = -0.184), and social support (ß = 0.185) were significant contributors to RNL total score (R2 = 0.583, p < .05). CONCLUSIONS: Results suggested that emotional measures of apathy, depression, anxiety, and happiness, but not general emotion, were important contributors to participation post-stroke. These findings suggest that rehabilitation professionals should address individual emotional contributors to facilitate participation post-stroke.

Apathy and residual neurological impairment are associated with community reintegration after mild stroke.

This study investigated the influence of apathy and positive social support on community reintegration after stroke. A prospective, correlational, cross-sectional design was used. 85 community dwelling participants with and without aphasia were included (≥ 18 years of age, first stroke, ≥ 6 months post-stroke). The Reintegration to Normal Living Index (RNL) measured poststroke participation. The Apathy Evaluation Scale (AES) and Positive Social Interaction domain of the Medical Outcomes Study Social Support Survey assessed apathy and social support respectively. NIH Stroke Scale measured residual neurological impairment. Apathy, social support, and stroke impairment together were strongly associated with the RNL and accounted for 51% of total variance in the RNL. The AES and NIHSS were independent predictors of the RNL, though positive social interaction failed to reach significance. Persons with and without apathy differed significantly on the RNL. Therefore, stroke rehabilitation should address apathy as a potential target for intervention. Future research should determine factors that mediate the relationship between poststroke apathy and community reintegration.

Self-reported emotional health and social support but not executive function are associated with participation after stroke.

BACKGROUND: Participation restrictions continue to be prevalent for community-dwelling stroke survivors. Research is needed to understand the associated post-stroke factors that limit or facilitate optimal participation and quality of life. OBJECTIVES: To investigate emotional health, executive functioning (EF), and social support as predictors of participation restrictions post-stroke. METHODS: Cross-sectional data collected from participants ≥ 6 months after mild stroke with and without aphasia (N = 114) were analyzed using three participation outcome measures: Reintegration to Normal Living Index (RNL), Activity Card Sort (ACS), and the Stroke Impact Scale (SIS) Version 2.0 Participation/Role Function domain. Predictor variables investigated were emotional health (SIS Emotion domain scores), EF (Delis Kaplan Executive Function System Trail Making Condition 4: DKEFS), social support (Medical Outcomes Study Social Support Survey: MOS-SSS), stroke severity (National Institutes of Health Stroke Scale: NIHSS), and education level. RESULTS: Using multiple regression, these predictors accounted for 26.4% to 40% of the variance for the three participation outcomes. Emotional health was a significant independent predictor across all three measures. Social support was a significant predictor of participation as measured on the RNL. Executive function was not a significant predictor of participation when controlling for the other predictor variables. CONCLUSIONS: Emotional health and social support should be considered as modifiable factors that could optimize meaningful participation and quality of life.

Apathy, Cognitive Impairment, and Social Support Contribute to Participation in Cognitively Demanding Activities Poststroke.

OBJECTIVE: To understand the extent to which apathy, cognition, and social support predict participation in activities with cognitive demands. DESIGN: Prospective, quantitative correlational, cross-sectional study. Setting. Outpatient treatment centers and community stroke support groups located in St. Louis, MO, and Boston, MA. Participants. 81 community-dwelling individuals ≥ 6-month poststroke with and without aphasia. Measures. Participants completed the Activity Card Sort (ACS), Apathy Evaluation Scale (AES), Medical Outcomes Study Social Support Survey (MOS-SSS), and Delis-Kaplan Executive Function System (DKEFS) Design Fluency and Trail-Making subtests. RESULTS: Cognitive deficits limit participation in activities with high cognitive demands. Apathy and positive social interaction influence participation, regardless of high or low cognitive demands. Poststroke aphasia did not impact return to participation in activities with high and low cognitive demands. Conclusions and Relevance. Cognitive deficits seen poststroke contribute to participation only for activities with high cognitive demands. Apathy has a significant and negative influence on participation overall. Social support is a modifiable contextual factor that can facilitate participation. Poststroke apathy can be detrimental to participation but is not well recognized. The availability of companionship from others to enjoy time with can facilitate participation.

Self-Perception of Physical Function Contributes to Participation in Cognitively- and Physically-Demanding Activities After Stroke.

Background: Persons with and without aphasia experience decreased participation in meaningful activities post-stroke that result in reduced autonomy and poorer quality of life. Physical, cognitive, and/or communication deficits are prevalent post-stroke and many activities given up are purported to require high levels of communicative, cognitive, or physical skill. However, the relationship between deficits after stroke and participation in life activities that appear to require high skill levels in these three areas has not been investigated fully. Objectives: The objectives of this study are to: (1) determine differences in reported participation in communicatively-, cognitively-, or physically-demanding activities in persons after stroke with and without aphasia living in the community, and to (2) investigate whether performance on commonly used self-perception assessments of these three areas predicts reported participation in activities requiring higher levels of skill in these domains. Methods: In a cross-sectional design, 82 individuals at least 6 months post-stroke with (N = 34) and without aphasia (N = 48) were administered a battery of neuropsychological and participation-based assessments. Supported communication techniques maximized inclusion of individuals with aphasia. A series of regression analyses investigated the relationship between self-perceived communicative, cognitive, and physical functioning and reported participation in activities post-stroke that required high amounts of skilled function in these areas. Results: People with and without aphasia did not differ in terms of the percentage retained in communicatively-, cognitively-, or physically-demanding activities. All individuals retained higher levels of participation in communicatively- and cognitively-demanding activities (at least 60% retained), compared to participation inphysically-demanding activities (about 50% retained). The strongest predictor for retaining participation in two of the three domains of activities was self-perception of physical function, though much of the variance remained unexplained. Self-perception of communication was not related to participation retention in any of the three domains. Significance of Impact: Rehabilitation professionals should be aware of the impact that a variety of communicative, cognitive, and physical factors may have on participation post-stroke. Self-perceptions of impairments in communication and cognition may not directly predict participation in activities requiring high levels of communicative and/or cognitive skill, at least for those with mild impairment, even though activities requiring those skills are given up or done less after stroke.

Influence of Environmental Factors on Social Participation Post-Stroke.

OBJECTIVES: For rehabilitation professionals to adequately address meaningful participation in social activities with their patients after a stroke, there must be a better understanding of neurobehavior, that is, how neurological impairment and its sequelae and environmental factors support or limit social participation. The current study examines how stroke severity (NIH Stroke Scale), its impact on perceived mobility (Stroke Impact Scale mobility domain), and the environment (MOS Social Support-Positive Social Interactions scale and Measure of Stroke Environment receptivity and built environment domains) influence social participation (Activity Card Sort: ACS). METHODS: A correlational, cross-sectional design examined the relationships among neurological impairment, perceived limitations in activity, environmental factors, and social participation. Participants included 48 individuals who were at least 6 months post-stroke both with aphasia (N = 22) and without aphasia (N = 26) living in the community for whom all measures were available for analysis. RESULTS: No differences in social participation were found between those with and without aphasia, though both groups reported a large (25-30%) decline in participating in their prestroke social activities. For the ACS Social Domain activities and ACS Partner to Do With activities (percent retained), 37% and 35% of the variance, respectively, was accounted for by the predictor variables, with only MOS Social Support making an independent contribution to social participation. In this sample, neurological impairment was not a significant correlate of social participation. Additionally, perceived mobility and the built environment were not found to independently predict participation in social activities. CONCLUSIONS: Perceived social support was found to predict social participation in individuals living in the community 6 months or greater post-stroke. Focusing on social support during post-stroke rehabilitation may provide an avenue for increased social participation and more successful community reintegration.
