Childhood abuse and stress generation: the mediational effect of depressogenic cognitive styles

According to the stress generation hypothesis (Hammen, 1991), depressed and depression-prone individuals experience higher rates of negative life events influenced by their own behaviors and characteristics (i.e., dependent events), which in part may account for the often recurrent nature of depression. Relatively little is known about the interrelation between stress generation predictors, and distal risk factors for this phenomenon. This study examined whether childhood emotional, sexual, and physical abuse, each uniquely predicted negative dependent events in individuals with a history of depression. The role of negative inferential styles as a potential mediator was also assessed. A sample of 66 adults with a history of depression completed self-report measures of childhood abuse history and negative inferential styles at baseline. The "contextual threat" method was used to assess the occurrence of negative life events over a 4-month prospective follow-up period. Childhood emotional abuse, but not sexual or physical abuse, prospectively predicted greater stress generation. Negative inferential styles mediated this relation. These findings suggest that targeting negative cognitive styles in clinical settings, especially in patients with a history of childhood emotional abuse, may be important for reducing the occurrence of negative life events, thereby possibly decreasing risk for depression recurrence.
