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.
