Turkish Adaptation and Validation of the Adolescent Sleep-Wake Scale

Abstract

Background and Objective The aim of our study was to evaluate the psychometric properties of the ASWS in a Turkish adolescent sample.Methods Two hundred and two Turkish high school students participated in our study. We used exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) for factor structure. McDonald’s ω and Cronbach’s α values were utilized for reliability analyses. We examined convergent validity by calculating correlations between the ASWS and sleep parameters and perceived stress scale scores.Results A 3-factor structure was detected, explaining 66.20% of the total variance with an eigenvalue above 1 in EFA. The 3-factor structure was confirmed with good fit indices in CFA. The scale demonstrated solid internal consistency (α = 0.844, ω = 0.832). We found a significant negative correlation between the ASWS and perceived stress, sleep latency, wakefulness after sleep onset, and ability to sleep after wakefulness at night.Conclusions The Turkish ASWS was found to be a valid and reliable instrument.
