Objective: The purposes of this study are to develop a diagnostic test for severity level of depressive disorders, which is contexualized to the users; and to study the validity of this test. Methods: this study was divided into two stages. First, a depressive disorder diagnostic te4st was developed by selecting dialects used among Thai I--san locals to express feelings occurred during the two weeks before the diagnostic test. The nine questions in the test mainly concerned the presence of depressed mood as detailed below. Question 1: low interest or pleasure in doing things (bor-yak-hed-yung, bor-son-jai-yung) Question 2: feeling down, depressed, or hopeless (bor-muan-bor-suen, seng,ngoi) Question 3: abnormal insomnia or abnormal hypersomnia (norn-bor-lub, ruelub-lub-tuen-tuen, rue-norn-bor-yak-look) Question 4: fatigue or loss of energy (muei,bor-mee-hang) Question 5: decrease in appetite or increase in appetite (bor-yak-khao, bor-yak-nam, rue-gin-lai-pode) Question 6: self-reproach or inappropriate guilt (khued-wah-chao-khong-bor-dee) Question 7: poor concentration or indecisiveness (khued-yang-kah-bor-ork) Question 8: an actual physical slowing of speech, movement and thinking (wao-ka-sah, hed-yang-ka-sah, rue-hon-huay, bor-pen-ta-yoo) Question 9: abnormal morbid thoughts of death or suicide (khued-yak-tai) The scores is ranged from 0 to 24 and classified into four levels with the scales of 0 to 3, with 0 meaning 'not at all', 1 is 'several days', 2 is 'morethan half the days', and 3 'nearly every day', Secondly, a cross sectional criterion standard validation study was conducted at Yasothorn province. The 1,002 volunteers aged 18 and older were interviewed by nurses using the 2-question Thai I-san screening test and diagnosed by the 9-questiondiagnostic test. After that participants were interviewed by a psychiatrist using the M.I.N.I. (Mini International Neuro-psychiatric Interview). The data were then analyzed by using STATA 8.0 to calculate the sensitivity, specificity, positive predictive value, negative predictive value, percentage of corrected classification, and prevalence of depressive disorder with 95% confidence interval. Results: The prevalence of depressive disorders was 5.6%, with 3.7% of Major depressive disorder, 2.4% of Dysthymia and 2.2% of Bipolar symptoms. The scale of 3 (nearly everyday) was found most in question 3 (4%) and in question 7 (1.9%) respectively. The average completion of the test was 1 minute. The validity of the 9-question test calculated at the score cut of point with Receiver Operating Characteristic Curve (ROC) was 0.9283 (95% CI=0.8931-0.9635); the sensitivity was 75.68%, and the specificity was 93.37%. The probability of depressive disorders was 11.41 times when compared to the diagnostic test of major depressive disorders. Conclusion: The 9-question depressive disorder diagnostic test using Thai I-san dialects seems to have high validity, appropriate number of items, and requires small amount of time. The significance of this tool was that it was used in Thailand for the first time and, more importantly, it was contextualized to the Thai I--san users.
