Testing the impaired disengagement hypothesis: The role of attentional control and positive metacognitive beliefs in depression.

The impaired disengagement hypothesis holds that people ruminate - and thus increase their risk for depression - due to impaired attentional control and conflict signaling. We tested this hypothesis by examining the role of attentional control and conflict signaling (operationalized as positive metacognitive beliefs) in rumination and depressive symptoms. We expected that attentional control and positive metacognitive beliefs would be associated with depressive symptoms and that these associations would be cross-sectionally mediated by rumination.
