TL;DR: Lovibond et al. as discussed by the authors examined the factor structure, reliability, and validity of the Depression Anxiety Stress Scales (DASS; S. H. Lovibond & P. F. Lempitsky, 1995) and the 21-item short form of these measures, and found that the DASS distinguishes well between features of depression, physical arousal, and psychological tension and agitation.

TL;DR: The Penn State Worry Questionnaire evidenced quite favorable internal consistency using GAD patients and each of the other anxiety disorder groups and normal controls, and correlations between the PSWQ and measures of anxiety, depression, and emotional control supported the convergence and discriminant validity of the measure.

TL;DR: Overall, the results offered good support for the notion that the trait scale of the STAI assesses depression, as well as anxiety.

TL;DR: In this article, the authors compared varying models of the perfectionism construct using the best known measures of perfectionism, and found that maladaptive evaluative concerns was more strongly associated with depression, anxiety, stress, and test taking anxiety.

TL;DR: The findings suggest that the STICSA may be a purer measure of anxiety symptomatology than is the STAI.
