Objectives: Although many tools have been developed to diagnose mental disorders so far, it has not been easy to administer because it is necessary to undergo training for the professionals as well as time required to administer those tools. The Psychiatric Diagnostic Screening Questionnaire; PDSQ, developed by Zimmerman et al, 2001, is self-reporting test for screening DSM-IV axis I disorders in clinical settings, and it is well known for its simplicity and availability. This study compared Korean PDSQ with Mini-International Neuropsychiatric Interview(M.I.N.I.-Plus) for their diagnostic availability, as a part of standardization of Korean version. Methods: The samples were 320 patients, who were selected from 3 university hospitals in Daegu and Kyoungbook for K-PDSQ and Mini-International Neuropsychiatric Interview(M.I.N.I.-Plus). The diagnostic correspondence, sensitivity, specificity and administering time were evaluated for PDSQ as well. Results: For the diagnostic correspondence of PDSQ, Cohen`s kappa coefficient was .69 between PDSQ and MINI-Plus. The administering time was 19.3±12.9min, which was similar to the M.I.N.I.-Plus` minutes. The sensitivity was higher than 90% in most of the 13 PDSQ subscales(MDD; 100%, PTSD; 75%, Bulimia Nervosa; 100%, OCD; 68%, Panic Disorder; 93%, Psychosis; 59%, Social Phobia; 98%, Alcohol Dependence/Abuse; 94%, Drug Dependence/Abuse; 100%, Agoraphobia; 83%, GAD; 88%, Somatoform Disorder; 100%, Hypochondriasis; 96%), and the AUC(area under the curve) values of them were above 0.79(MDD; 0.91, PTSD; 0.82, Bulimia Nervosa; 1.00, OCD; 0.80, Panic Disorder; 0.94, Psychosis; 0.79, Social Phobia; 0.87, Alcohol Dependence/Abuse; 0.96, Drug Dependence/Abuse; 1.00, Agoraphobia; 0.92, GAD; 0.81, Somatoform Disorder; 0.99, Hypochondriasis; 0.97). Conclusion: PDSQ showed significant diagnostic correspondence. time-efficiency and high level of sensitivity and specificity. PDSQ is considered to be useful diagnostic tool before the first interview of the patients for the screening of DSM-IV Axis I diagnosis because it is simplicity and reliability.
