The Development of the Korean Version of Personality Disorder Questionnaire-Revised : PDQ-R) : Evaluation of the Test Reliability and Validity

Objects :The clinical importance of personality disorder(PD) is becoming increasingly apparent because axis II pathology has been shown to adversely affect treatment response. Therefore, recognition o f P D in clinical as well as research settings should receive greater emphasis. Among the numbers of new instruments designed to assess PD, the Personality Disorder Questionnaire- Revised (PDQ-R) , self-report questionnaire, contains criteria precisely matching DSMIII- R criteria and is very easy to administer and to score. We tested here the reliability and validity of the Korean version of PDQ-R. Methods : The subjects were consisted of 217 controls drawn from various groups of general population by cluster sampling methods and 32 P D patients. We administered the 125-item Korean version of PDQ-R and tested internal consistency, test-retest reliability and discriminant validity. Results : In 217 general population, internal consistency was above .400(range : 254 to .596) in most PD categories. After deleting 30 items which had weak correlation coefficient, Crohnbach alpha of PDQ-R items in all P D exceeded .400( range : .419 to .632). Test-retest reliability done 1-week interval was above .500 except borderline and sadistic PD. To evaluate the discriminant validity, we administered PDQ-R to 143 normal controls and 32 PD patients. There were significant differences in total PDQ-R score between groups when controlled the effects of age, sex, educational level. Conclusion : Our results indicated that the Korean version of PDQ-R had reasonable reliability and validity and might be useful in screening for overall personality disturbances.
