Knowledge of grocery shopping skills as a mediator of cognition and performance.
OBJECTIVE
Cognitive impairments in serious mental illness are associated with poorer community outcomes; yet the mechanisms through which cognition limits functioning are unknown. This study examined knowledge of grocery shopping skills as a mediator of cognition and performance of grocery shopping skills.


METHODS
Fifty-one individuals with serious mental illness were administered measures of cognition, as well as measures of knowledge and performance of grocery shopping skills.


RESULTS
When knowledge of grocery shopping skills was introduced as a mechanism through which cognition influences performance, almost perfect mediation was achieved (slope of the regression dropped from B=.32 to B=.03).


CONCLUSIONS
The search for mediators can improve our understanding of how cognition influences community functioning.
