Dysfunctional attitudes, attributional styles, and phase of illness in bipolar disorder

Whereas an abundance of studies have been devoted to the study of cognitive vulnerability in unipolar depression, comparatively less is known regarding the cognitive styles of patients with bipolar disorder. This study examined the cognitive styles of 395 of the first 500 bipolar patients enrolled in the NIMH Systematic Treatment Enhancement Program for Bipolar Disorder as a function of mood state at study entry. Patients completed diagnostic and mood assessments and two measures of cognitive style: The Dysfunctional Attitudes Scale (DAS) and the Attributional Style Questionnaire (ASQ). Patients in mixed episodes exhibited significantly more negative dysfunctional attitudes and negative attributional styles than euthymic patients and significantly more dysfunctional attitudes than manic/hypomanic patients. The implications of these findings are discussed in relation to episode vulnerability, mood-state dependency of cognitive style, and cognitive-behavioral treatment. © 2008 Springer Science+Business Media, LLC.
