Psychometric properties of the Depressive Experiences Questionnaire for adolescents.
Items of the Depressive Experiences Questionnaire (DEQ) were rephrased and simplified to make them appropriate for younger subjects. This adolescent form of the DEQ (DEQ-A) was administered to high school students; a factor analysis revealed three factors that were highly congruent in female and male students and with the three factors of the original DEQ. Internal consistency as well as short- and long-term reliability for each of the 3 DEQ-A factors were at acceptable levels. Each factor correlated highly with its counterpart factor in the original DEQ, especially the Dependency and Self-Criticism factors. Correlations of the DEQ-A factors with other measures of depression essentially replicate relationships found between these measures of depression and the original DEQ for adults. The reliability, internal consistency, and validity of the DEQ-A indicate that it could be useful in studying depressive experiences in younger adolescents.
