This paper describes the clinical validation of the 10-question Short Zung Interviewer-assisted Depression Rating Scale (Short Zung I.D.S.) which has been derived from the 20-question Zung Self-rating Depression Scale (Zung S.D.S) for use in the elderly. The Short Zung I.D.S. was administered to 104 elderly volunteers from the community and to 33 elderly depressed patients assessed by a psychiatrist. The mean scores (41.3 and 81.0, respectively) were significantly different (P less than 0.0001). The Short Zung I.D.S. has proved to be a useful brief screening test for depression in the elderly and should be of value in measuring changes in mood.
