A longitudinal model of social contact, social support, depression, and alcohol use

The longitudinal relations among contact with one's social network (social contact), perceived social support, depression, and alcohol use were examined. An integrative model was developed from affect regulation theory and theories of social support and dysfunctional drinking. Data were obtained from. a random sample of 1,192 adults. The 3-wave panel model was tested using structural equation modeling analysis. Results revealed that (a) social contact was positively related to perceived social support; (b) perceived social support was, in turn, negatively related to depression; and (c) depression was, in him, positively related to alcohol use for 1 of 2 longitudinal lags. There was partial support for the feedback hypothesis that increased alcohol use leads to decreased contact with family and friends. Although the results generally supported the authors' hypotheses, the significant coefficients in the model were generally small in size.
