ABSTRACT

Indonesian adolescents are increasingly dependent on smartphones, often using them during bedtime, which may affect sleep quality. To examine the relationship between smartphone usage intensity and sleep quality among adolescents at SMP Negeri 1 Susukan Lebak, Cirebon Regency. A cross-sectional correlational study involving 220 students selected through stratified random sampling. Data were collected using the Smartphone Usage Intensity Questionnaire and the Adolescent Sleep-Wake Scale, and analyzed using Spearman’s rank correlation. The majority of respondents had moderate smartphone usage (53.2%) and poor sleep quality (50.9%). There was a strong negative correlation between smartphone usage intensity and sleep quality (p = 0.000; r = -0.645). Higher smartphone usage intensity is associated with poorer sleep quality. Health promotion efforts targeting adolescents and parents are needed to address this issue.

Keywords: Adolescent, Sleep Quality, Smartphone Usage Intensity.
