The prevalence of cognitive distortion in depressed adolescents.

This study examined the prevalence of cognitive distortion in depressed adolescents. Ninety-four consecutive depressed adolescent psychiatric outpatients were administered the Beck Depression Inventory, the Dysfunctional Attitude Scale, the Interpersonal Dependency Inventory and the Maudsley Personality Inventory. Depressed patients who scored above a threshold for cognitive distortion were compared to those who fell below the threshold. Of the depressed patients, 47.4% were found to meet the severity criteria for cognitive distortion, while the remaining 52.6% were found to be below the severity threshold. Cognitive distortion was associated with more severe symptoms of depression, lack of social self confidence and greater introversion. These results do not support the hypothesis that cognitive distortion is universal in clinical depression. However, they do suggest that cognitive distortion is associated with more severe depression.
