The Effect of Internet Addiction on Daytime Sleepiness and Quality of Life in Adolescents

Objective: This study was conducted to determine the effect of internet addiction on daytime sleepiness and quality of life in adolescents. Method: The population of the study consisted of a total of 427 (7th and 8th grade) students who attended the Şehit Nihat Şener Secondary School in Adana province between January and March 2022. The study was conducted with 342 students without sample selection. The data were collected using the “Socio-demographic Data Form”, “Problematic Internet Usage Scale-Adolescent”, “Paediatric Quality of Life Inventory”, and Paediatric Daytime Sleepiness Scale. The data were analysed using Kruskal-Wallis, Mann-Whitney U and multiple regression tests. Necessary permissions were obtained to conduct the study. Findings: A statistical significant difference was found between the mean scores of PIUS-A, PDSS, and PedsQL in terms of the days and time intervals in which adolescents frequently used the internet, the duration of daily use of the internet, use of phone-tablet in bed, and parental supervision of internet use (p < 0.05). The statistical estimates for the regression model run to analyse the effects of the Problematic Internet Usage Scale-Adolescent and its subscales on daytime sleepiness and quality of life indicated that the model was significant and applicable (p < 0.001). Conclusion: This study revealed that problematic internet use by the adolescents negatively affected daytime sleepiness and quality of life.
