Predicting depression from temperament, personality, and patterns of social relations

The present study used a levels-of-analysis perspective (McAdams, 1995) to link temperament to depression. We hypothesized a mediational role for three personality variables (Agreeableness, Extraversion, Neuroticism) and two interpersonal variables (social support and negative social exchange) in channeling the effects of temperament. A structural equation modeling approach supported the hypothesis that these three personality variables were mediators of the link between temperament and depression. The patterns of mediation differed for Agreeableness, Extraversion, and Neuroticism. In addition to the three personality variables, social support and negative social exchange were also found to mediate the effects of temperament. There was no evidence that patterns of relations among the variables differed between males and females. Results are discussed in terms of a levels-of-analysis approach to the examination of the effects of temperament and personality on adaptation outcomes.
