초록

The purpose of this study was to analyze the longitudinal changes and other relevant factors of adolescents’ sleep duration. The subjects comprised 2,215 students who participated in the Korean Children & Youth Panel Survey 2010(KCYPS 2010) from 2012 to 2016. The data were analyzed by latent growth modeling using SPSS21.0 and AMOS24.0. Our results were as follows. First, the result showed that students’ sleep duration changed in linear manners over the three years of the study and there were individual differences in intercepts and linear slope. Second, students’ study time had contemporaneous effects on sleep duration in these three years, and electronic media usage time had only contemporaneous effects in 2014 and 2015. The intercepts of adolescents’ sleep duration in 2013 significantly affected the depression, somatization, and aggression symptoms reported in 2016. This study highlights the importance of long-term sleep duration management for the psychological-emotional adaptation of adolescents.
