Objective: 1) To develop a screening test for depressive disorders that is simple and short. 2) To determine the diagnostic accuracy of the screening test for depressive disorders in Northeastern Thai community. Methods: This study had 2 stages. First, we developed a screening test of depressive disorders by selection the dialect words to express depressive mood among Northeastern Thai people. This test consists of two questions. The first question is presence of depressed mood: during the past month have your have often been bothered by feeling down, depressed, distress, irritable and easily cry? The second question is: loss of interrest or pleasure in doing things. In the second stage, we conducted cross sectional criterion standard validation study in 17 villages in 9 districts of Yasothorn province. 1,002 volunteers with age of 18 and older were interviewed by nurses using two-question screening test before sent to psychiatric to interview using Mini International Neuropsychiatric Interview (M.I.N.I.), a structured interview for diagnosis of depressive disorders. Data analysis was used STATA 8.0 to calculate the sensitivity, specificity, positive predictive value, negative predictive value, percent of corrected classified, and prevalence of depressive disorder with 95% confidence interval. Results: Of 1,002 participants, female were predominated (58%), with mean age of 41.5, Overall, 5.6% (56/1002) of the community participants had been diagnosed for Depressive disorders: Major depressive disorder was 3.7%, Dysthymia was 2.4 and Bipolar was 2.2%. The first question of screening test was more positive 3 times than the second one. It showed a high sensitivity of 96.5% (95% CI =95.4-97.6%) but low specificity of 45.6% (955 CI =42.5-48.7%). The second question showed a low sensitivity of 71.9% (95% CI =69.2-74.7%) but high specificity of 84.1% (95% CI =81.9-86.4%). When either one of two questions was positive, this test showed sensitivity of 96.5% (95% CI = 95.4-97.6%) or the positive likelihood ratio was 1.74. If both of two questions were positive, it showed high specificity of 85.1% (95% CI= 82.9-87.3%) and the positive likelihood ratio was 4.82. Conclusion: Two questions for screening for depression would detect most cases of depressive disorders in community, which has the advantage of brevity, high sensitivity and specificity.
