ABSTRACT J Korean Neuropsychiatr Assoc Vol 39, No 3, May, 2000 The Preliminary Study of Reliability and Validity on the Korean Version of Personality Disorder Questionnaire-4PDQ-4 Dong In Kim, M.D., Mal Rye Choi, M.D., Eun Chung Cho, M.A. Department of Neuropsychiatry, Presbyterian Medical Center, Chonju ObjectivesThe purpose of this study was to examine the reliability and the validity of the Korean version of Personality Disorder Questionnaire-4PDQ-4. MethodsPDQ-4 was administered to 540 subjects of general population group and 37 subjects of personality disorder group. For measuring concurrent reliability, we tested internal consistency, splithalf reliability, test-retest reliability and correlation of item score of subscale and mean of subscale. And also, we performed factor analysis for the evaluation of validity, and t-test to group difference of the total scores between general population group and personality disorder group. ResultsIn general population group and personality disorder group, internal consistency was above.500range of Cronbach alpha.4007 to.6693 in most of the Personality disorder categories. Split-half reliability was.839 between even and odd items. Test-retest reliability done 2 weeks interval was.868. Item scores of subscales and mean of subscales showed high correlation coefficient. Group difference of the total scores between general population and personality disorder group showed very significant differencet9.146, df76, p.000. ConclusionThe PDQ-4 shows a reasonable degree of reliability and validity and could be a valuable tool in screening for overall personality disturbances.
