Using a computer-assisted technique of searching exhaustively for combinations of items, a brief instrument was developed to identify cases of depression in the physically ill. The search technique, using Quality ROC as the measure of test efficiency, was employed on a sample of 120 patients and then the rules were applied to a validation sample. All patients had completed a 60-item self-report inventory (GHQ), the Hospital Anxiety and Depression (HAD) scale and the Beck Depression Inventory (BDI), and had undergone a structured diagnostic interview. The derived instrument of 4 items performed better than the standard GHQ, HAD, and BDI in identifying patients with DSM-III-R defined depression.
