The depression proneness rating scale: Reliability, validity, and factor structure

This study describes the development of the Depression Proneness Rating Scale (DPRS), a brief, self-administered measure of the tendency to experience frequent, long-lasting, and severe depressions, and three investigations into the scale’s reliability, validity, and factor structure. Study 1, using 100 university students, found a stability coefficient of .82 for the DPRS over a test-retest interval of nine weeks. Further, Time 1 (T1) DPRS scores predicted Time 2 (T2) symptoms of depression, even after adjusting for Time 1 symptoms (R2 Change=.03). Study 2, using 440 university students, found the DPRS to be a better predictor of past depressive episodes (r=.41 to .47) than was the Beck Depression Inventory (r=.32). Study 3, using 1101 university students, found that all 13 items of the DPRS loaded .40 or greater on a single factor for both males and females. Overall, results provide substantial evidence for the DPRS as a valid, unidimensional, and practical measure of depression proneness.
