Psychometric properties of the Depressive Experiences Questionnaire in a college population.

The Depressive Experiences Questionnaire (DEQ; Blatt, D'Afflitti, & Quinlan, 1976) was developed to permit the study of the continuities between normal and pathological forms of depression. Since its publication over 10 years ago, the DEQ has been increasingly used in a wide range of investigations of depression in clinical and nonclinical samples and as a measure of two major personality dimensions in a number of studies of differential responsiveness to various life stressors. This study provides an analysis of the DEQ responses in a large sample of undergraduate subjects in an attempt to articulate more clearly the psychometric properties of the DEQ. The DEQ consists of 66 items describing experiences frequently reported by depressed individuals. In the original development of the DEQ, factor analyses using male and female undergraduate samples yielded three orthogonal factors, Dependency, Self-Criticism, and Efficacy (Blatt et al., 1976). Most subsequent studies have used the factor scoring coefficients from the female sample to score men and women's DEQs. The factor loadings in the new male and female samples were very similar to one another and to the original female factor loadings. Thus, the continued use of the scoring parameters from the original female sample is recommended. Factor scores for Dependency and Self-Criticism continue to be uncorrelated in both men and women. Normative data are presented from the new samples, with men scoring higher on Self-Criticism and women scoring higher on Dependency.
