Coping and depression. The relative contribution of internal and external resources during a life cycle transition.

This study addresses two questions relevant to psychiatric epidemiological models of the stress-distress relationship: Are personality and social support resources independent phenomena or highly correlated? and What are the relative contributions of these two types of resources in protecting against the development of depressive symptomatology? A cohort of beginning medical students was administered self-report questionnaires measuring social supports, locus of control, interpersonal dependency, and depressive symptomatology. On the basis of correlation and regression analysis, the data show that the personality characteristics more strongly predict depressive symptomatology than do social supports, and that social supports are unrelated to locus of control but directly correlated with interpersonal dependency. The authors discuss these findings in the context of a life cycle transition.
