An exploration of linear and curvilinear relationships between community participation and neurocognition among those with serious mental illnesses.

OBJECTIVE

Longitudinal research supports an effect of participation in aspects of community life (e.g., leisure activity, employment) on neurocognition in the general population. This study examined the extent and nature of the relationship between community participation and neurocognition among people with serious mental illnesses.

METHOD

Participants included 168 adults with schizophrenia spectrum or affective disorder diagnoses who completed the Temple University Community Participation Measure and Brief Assessment of Cognition in Schizophrenia. Hierarchical multiple regression analyses explored linear and curvilinear effects of the amount and breadth of community participation on neurocognition.

RESULTS

Significant linear relationships existed between amount of community participation and overall neurocognitive functioning, motor speed, verbal fluency, and attention/processing speed, and between breadth of participation and verbal fluency. Significant curvilinear effects were noted between amount of community participation and verbal memory, and between breadth of community participation and overall neurocognitive functioning and motor speed.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Findings suggest that enhanced community participation may contribute to improved neurocognitive functioning, further supporting the importance of this rehabilitation target. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
