Abstract

Abstract: Background and objectives: The cognitive catalyst model posits that rumination and negative cognitive content, such as negative schema, interact to predict depressive affect. Past research has found support for this model using explicit measures of negative cognitive content such as self-report measures of trait self-esteem and dysfunctional attitudes. The present study tested whether these findings would extend to implicit measures of negative cognitive content such as implicit self-esteem, and whether effects would depend on initial mood state and history of depression. Method: Sixty-one undergraduate students selected on the basis of depression history (27 previously depressed; 34 never depressed) completed explicit and implicit measures of negative cognitive content prior to random assignment to a rumination induction followed by a distraction induction or vice versa. Dysphoric affect was measured both before and after these inductions. Results: Analyses revealed that explicit measures, but not implicit measures, interacted with rumination to predict change in dysphoric affect, and these interactions were further moderated by baseline levels of dysphoria. Limitations: Limitations include the small nonclinical sample and use of a self-report measure of depression history. Conclusions: These findings suggest that rumination amplifies the association between explicit negative cognitive content and depressive affect primarily among people who are already experiencing sad mood. Highlights: Explicit cognition interacted with rumination to predict dysphoric affect. Rumination × Cognition interaction impacted people already high in dysphoric affect. Past depression sensitized people to rumination when their state self-esteem was low. Implicit self-esteem did not moderate the impact of rumination on dysphoric affect.
