Effect of Excessive Use of Cell Phones on Students' Academic Achievement with a Mediating Role of Sleep Quality


The present study aims to investigate the effect of excessive cell phone use on students' academic achievement with a mediating role on sleep quality. This study's statistical population comprises 392 first- and ninth-grade female students from Amol. According to the Krejcie Morgan table, a sample size of 194 persons was computed. In addition, a basic random sampling approach was applied. Standard questionnaires adapted from Hay (2009) and a sleep quality questionnaire designed by Petersburg (1989) were used as assessment methods. Additionally, the grade point average of high school students in the first semester of the academic year 2018-19 was utilized to assess academic achievement. Face validity was employed under the observation of supervisors and consultants to assess the questionnaire's validity. The reliability coefficients of excessive use of cell phones, sleep quality, and academic accomplishment was 0.75, 0.79, and 0.80, respectively, and all variables had a value larger than 0.7, confirming the reliability. The study hypotheses were tested using structural equation modeling and SmartPLS2 software. The results indicated that excessive use of cell phones has an effect on students' academic achievement with a mediating role on sleep quality; excessive cell phone use affects students' academic achievement; excessive cell phone use affects the quality of students' sleep, and sleep quality affects students' academic achievement.
