Abstract
Objective We tested the hypotheses that the number of close social network members and the health-related support provided by social network members are predictive of coping efficacy and health behaviors. Methods Cross-sectional data were collected from 115 African Americans enrolled in cardiac rehabilitation. Measures included the social convoy model, SF-36, the Social Interaction Questionnaire, the Patient Self-Efficacy Questionnaire, and an investigator-developed assessment of health behaviors. Results Bivariate relationships were found between the number of inner network members and coping efficacy ( r = .19, P < .05) and health behaviors ( r = .18, P < .06), and between health-related support and coping efficacy ( r = .22, P < .05) and health behaviors ( r = .28, P < .001). Regression analyses support the hypothesis that close network members predicted better coping efficacy (β = .18, P < .05) and health behaviors (β = .19, P < .05). Health-related support also predicted coping efficacy (β = .23, P < .05) and health behaviors (β = .30, P < .01). Conclusion African Americans with larger inner networks have more health support, better health behaviors, and higher coping efficacy. The number of close social network members and related health-support promote health through health behaviors and coping efficacy.
