The influence of premorbid psychosocial factors on physical function and institutionalization 6 weeks after hospital discharge was studied in elderly stroke patients. The predictor variables of interest were social networks, availability of social support, pre-stroke depression (CES-D), and religiousness. The data were obtained from a prospective longitudinal study based on 2,812 noninstitutionalized individuals aged 65 years and older living in New Haven, Connecticut. Incident stroke cases from this study were followed for post-stroke outcomes. Results from 87 survivors indicated that larger social networks were associated with fewer limitations in physical function, controlling for relevant health and sociodemographic conditions. Larger networks were also associated with a lower risk of institutionalization (p < .05). None of the other psychosocial factors assessed appeared to be related to these outcomes.
