Abstract: Psychometric properties of the Korean versions of three sleep evaluation questionnaires were described to provide tools for practitioners and researchers interested in transcultural studies in Korea. The Pittsburgh Sleep Quality Index (PSQI), the General Sleep Disturbance Scale (GSDS), and the Leeds Sleep Evaluation Questionnaire (LSEQ) were analyzed using data from 959 community-dwelling adults in Korea. Furthermore, cut-off points and prevalence of sleep disturbance were identified. Reliability and concurrent validity for all measures were acceptable. Optimal cut-off points of PSQI, GSDS, and LSEQ with highest Youden’s index were 5, 33, and 66, and prevalence of sleep disturbance was 22.1%, 26.3%, and 25.8%, respectively. The Korean PSQI, GSDS, and LSEQ are all valid and reliable tools for detecting sleep disturbance. We provide suggestions for selecting the right tools according to the purpose, setting, and participants of transcultural studies
