Do negative cognitive styles confer vulnerability to depression?

According to the cognitive-vulnerability hypothesis of depression, negative cognitive styles confer vulnerability to depression when people confront n egative life events. In this article, we present evidence that negative cog nitive styles do indeed confer vulnerability to clinically significant depr essive disorders and suicidality and discuss possible developmental anteced ents of cognitive vulnerability to depression. We consider the issue of sta bility versus change in cognitive vulnerability to depression and discuss t he broader implications of the cognitive-vulnerability findings for mental and physical health.
