Korean Versions of Self-reported Sleep Questionnaires for Research and Practice on Sleep Disturbance

Abstract

PURPOSE: To identify Korean versions of self-reported sleep questionnaires for cross-cultural research and practice on sleep disturbance, we searched self-reported sleep questionnaires which have been developed to measure general sleep patterns. They should be qualitative, easy to take permission, do not obligate to pay, do not need any skill or professional help for scoring and have been reported high reliability and validity. METHODS: General Sleep Disturbance Scale (GSDS), Leeds Sleep Evaluation Questionnaire (LSEQ), and Pittsburgh Sleep Quality Index (PSQI) were identified based on all criteria. Korean version of GSDS, LSEQ, and PSQI were developed according to the methods combined the guidelines for the process of cross-cultural adaptation of self-reported measures with decentering method. RESULTS: Three Korean versions of self-reported sleep questionnaires were suitable for epidemiological study. They are not full length and easy to read. It requires less than 10 minutes for each subject to complete as well as for researchers to score. CONCLUSION: Psychometric analysis study is necessary to evaluate the reliability and validity of those Korean versions of self-reported sleep questionnaires.
