Direct assessment of depression by microcomputer. A feasibility study.

A self-rating depression questionnaire based on the Hamilton Depression Questionnaire was given directly by a microcomputer to 43 controls and 125 depressed patients. Scores obtained from the two groups differed very significantly; choosing an appropriate cut-off point, the computer-delivered questionnaire accurately detected the presence of depression. The severity of depression in the patients, as indicated by their scores, correlated significantly with assessments of severity by qualified clinicians. Patients commented favourably on the procedure, and the medical and nursing staff found it instructive and helpful. The use of this technique appears practicable and further evaluation is in progress.
