Social Support Mediates the Association Between Abilities and Participation After Stroke.

Abstract

Stroke survivors face participation restrictions, yet little is known regarding how social support affects the association between an individual's abilities and participation. Through a Person-Environment-Occupation-Performance (PEOP) model lens, social support was examined as a potential mediator between ability and participation in cognitively and mobility-demanding activities for stroke survivors with aphasia (persons with aphasia [PWA]) and without aphasia (persons without aphasia [PWOA]). A cross-sectional design, including PWA (n = 50) and PWOA (n = 59) examined associations among person factors (physical impairment, cognition), an environmental factor (social support), and occupational participation through cognitively- and mobility-demanding activity subscales of the Activity Card Sort. Cognition was associated with participation in cognitively demanding activities for both groups, though social support was a mediator only for PWA. Physical impairment was associated with participation in mobility-demanding activities for PWOA, though social support did not mediate that relationship. Social support is key to PWA participating in cognitively demanding activities post-stroke.
