title: Vulnerability to depressive mood reactions: toward a more powerful test of the diathesis-stress and causal mediation components of the reformulated theory of depression.
abstract: To provide a more powerful test of the diathesis-stress component of the reformulated theory of depression (Abramson, Seligman, & Teasdale, 1978), we extended and refined the Metalsky, Abramson, Seligman, Semmel, and Peterson (1982) study and examined whether the content of college students' attributional styles (hypothesized attributional diathesis) as measured at Time 1 interacted with the outcomes students received on a class midterm exam to predict their subsequent depressive mood responses. In addition, to test the mediation component of the theory, we examined whether the relation between the hypothesized attributional diathesis and failure students' subsequent depressive mood responses to their low midterm grades was mediated by the particular causal attributions these students made for their low grades. The results partially corroborated the current statement (Abramson, Alloy, & Metalsky, 1986; Abramson, Metalsky, & Alloy, 1986a, 1986b) of the diathesis-stress component of the theory. Whereas students' immediate depressive mood reactions were predicted solely by the outcomes they received on the class midterm exams, their enduring depressive mood reactions were predicted solely by the hypothesized Attributional Diathesis X Outcome on Midterm Exam interaction. The direction and form of the interaction were in line with prediction. The results fully corroborated predictions derived from the mediation component of the theory as they applied to students' enduring mood responses.
