Development of North Korean Version of the Composite International Diagnostic Interview / 신경정신의학

ABSTRACT

OBJECTIVES: The aim of the study was to develop a North Korean version of the Composite International Diagnostic Interview (NK-CIDI) and to evaluate the reliability and validity of NK-CIDI. METHODS: Subjects were 100 North Korean defectors, aged 18 to 65, who were recruited in a center for defectors in the National Medical Center or who were on an education curriculum in the defector settlement support center. NK-CIDI was developed based on the Korean version of CIDI considering the sociocultural background of North Korea. Inter-rater reliability, test/retest reliability, and validity of NK-CIDI were evaluated and kappa value was calculated. RESULTS: Different vocabularies and awkward expressions were adjusted, and additional explanations were supplemented for difficult phases. The target for development of NK-CIDI was early defectors who entered South Korea less than 3 months ago. Inter-rater reliability (n=30, kappa value 0.35-1.00), test/retest reliability (n=30, kappa value 0-0.86), and diagnostic validity (n=100, kappa value -0.02-0.42) were evaluated. CONCLUSION: Compared to the general population, defectors experience more psychiatric issues, and a standardized tool for diagnosis is needed. In this study, NK-CIDI was developed and the results suggest that reliability is acceptable but validity needs further verification. NK-CIDI could be utilized in future epidemiologic studies.
