Effects of Smartphone Overuse on Academic Delay Behavior by Some Dental Hygiene Students: The Mediating and Moderating Effects of Sleep Disorder Characteristics

Objectives: This study examines the mediating and moderating effects of characteristics of sleep disorders on the impact of smartphone overuse on academic delay in dental hygiene students. Methods: A survey was conducted from October 19 to November 27, 2020, targeting 164 dental hygiene students in Busan and Daejeon. The analysis method used the SPSS 26.0 program. Results: As a result of analyzing the characteristics of sleep disorders, it was found that as the characteristics of sleep disorders increased, the influence of excessive use of smartphones on academic delay behavior increased (p<.001). Sleep disorder characteristics were found to partially mediate smartphone overuse and academic delay behavior, indicating that the sleep disorder characteristics were significant. Conclusions: This study explores the relationship between smartphone use and the sleeping habits of dental hygiene students and the impact of these factors on academic performance
