Are dysfunctional attitudes in depressive disorder trait or state dependent?

The aim of this study was to investigate whether euthymic patients in remission on lithium prophylaxis score higher on the Dysfunctional Attitude Scale (DAS) than healthy subjects, thus indicating a trait quality of dysfunctional attitudes in unipolar depression. A total of 79 patients with recurrent unipolar depressive episodes and 79 individually matched healthy controls were compared using a Swedish version of the DAS. The results indicate that DAS score is a state-dependent variable in depressive disorder.
