A psychiatrist devised a short screening test for depression. An independent blind comparison was made with a gold standard for diagnosis of depression among 215 psychiatric outpatients. Among the 69 outpatients found to be depressed according to the gold standard, 44 patients were positive for the test. Among 146 patients found not to be depressed according to the gold standard, 39 patients were found to be positive for the test. 1. False-negative error rate 2. False-positive error rate 3. Positive predictive value
