title: Impact of social support, social cognitive variables, and perceived threat on depression among adults with diabetes.
abstract: Tested was a model of social support and cognitive appraisal of self-efficacy, outcome expectancies, and illness threat on depression. Study participants were community-dwelling adults with diabetes who completed a mailed questionnaire (N = 362). Results of structural equation modeling indicated that 52% of the variance in depression was explained by the model--largely by the direct effects of physical functioning, the perceived availability of social support, and the perceived threat of diabetes as well as the indirect paths from perceived support to perceived threat and from physical functioning to perceived support and perceived threat of diabetes. Diabetes-specific social support, self-efficacy, and outcome expectancies were not significant predictors of depression.
