Purpose: This study was done to verify the reliability and validity of the Korean version of DMCI in Korean adolescents.
Methods: A methodological study design was used with Cronbach¡¯s for reliability, and an exploratory factor analysis and contrasted groups approach for construct validity. DMCI was translated into Korean and tested with a sample of 406 adolescents in Korea. The data were analyzed using Cronbach¡¯s , item correlation with total, principal component factor analysis, and t-test.
Results: The translated content of the DMCI was validated by nursing faculty members and translation equivalency was obtained. The Cronbach¡¯s of the DMCI simplified with 18 items was .78. The factor analysis revealed three factors explaining 41.5% of total variance and the corresponding factors were self-observation (21.6%), self-judgement (11.4%), and self-confidence (8.6%). The mean score for the DMCI in the aggression group was significantly lower than the non-aggression group.
Conclusion: Results of this study suggest that the Korean version of DMCI can used as a reliable and valid measure to assess decision making competency in Korean adolescents.
