title: Anxiety, depression, and the content of worries.
abstract: Worry content as assessed by using a modified Worry Domains Questionnaire (WDQ) was compared among participants diagnosed with a depressive disorder, generalized anxiety disorder (GAD), and both a depressive disorder and GAD. A discriminant function analysis of worry domains yielded two significant functions. The worry domains Lack of Confidence, Aimless Future, Relationships, and Financial Concerns loaded significantly on Function 1, which was termed "Depressive Worries." The worry domain Loss of Control loaded significantly on Function 2, which was termed "Anxious Worries." The three participant groups differed in their pattern of worries in a way that lends support to the content-specificity hypothesis for both depression and anxiety. In addition, multiple regression analysis indicated that WDQ domain scores (in particular the Aimless Future domain) predicted the severity of depressive symptoms even after the variance contributed by anxiety symptoms was removed from the analysis. These findings suggest that the content of a person's worries may be significantly associated with the presence of depression, anxiety, or comorbid depression and anxiety.
