Abstract

Distinguishing between depression and anxiety has been a matter of concern and controversy for some time. Studies in normal samples have suggested, however, that assessment of two broad mood factors--Negative Affect (NA) and Positive Affect (PA)--may improve their differentiation. The present study extends these findings to a clinical sample. As part of an ongoing twin study, 90 inpatient probands and 60 cotwins were interviewed with the anxiety and depression sections of the Diagnostic Interview Schedule (DIS; Robins, Helzer, Croughan, & Ratcliff, 1981). Respondents also completed trait NA and PA scales. Consistent with previous research, NA was broadly correlated with symptoms and diagnoses of both anxiety and depression, and acted as a general predictor of psychiatric disorder. In contrast, PA was consistently related (negatively) only to symptoms and diagnoses of depression, indicating that the loss of pleasurable engagement is a distinctive feature of depression. The results suggest that strenghtening the PA component in depression measures may enhance their discriminative power. (PsycINFO Database Record (c) 2008 APA, all rights reserved)
