The Korean version of the Barkley Deficits in Executive Functioning Scale (K-BDEFS) was developed for assessment of daily executive functioning in adults with attention-deficit/hyperactivity disorder (ADHD). The original BDEFS has demonstrated good psychometric properties. The purpose of the current study is to examine the psychometric properties of K-BDEFS in Korean samples. The study sample consisted of 1,016 community-dwelling general adults from 4 regional areas (i.e., Seoul, Gyeonggi, Cheongju, and Jinju) across South Korea. We examined the factor structure, internal consistency, and convergent validity, and divergent validity of the K-BDEFS in the sample and construct validity of the K-BDEFS was examined by the confirmatory factor analysis. The Cronbach’s alpha value for K-BDEFS was 0.98 and all subscales and indices demonstrated good internal consistency, and K-BDEFS demonstrated good test-retest reliability. The convergent and divergent validity of the K-BDFES were confirmed. A confirmatory factor analysis supported the five factor model of the K-BDEFS as presented in the original version of the BDEFS. K-BDEFS demonstrated satisfactory reliability and validity. Its utility in clinical and research settings appeared to be feasible in Korea. Further studies are required to examine the psychometric properties among clinical populations and the ecological validity of this scale.
