The Impact of Social Network Addiction on Academic Achievement of Stu-dents: the Mediating Role of Sleep Quality, Academic Procrastination and Academic Stress

The current study aimed to examine the mediating role of academic procrastination, academic stress and sleep quality on the causal relationship between social network addiction and academic achievement of the high school students. This research is a descriptive correlational study. Statistical population covered all the students in Urmia high schools. Study participants were 204 female and 156 male students who were selected through cluster random sampling. Data were collected by using Turel and Serenko’social network addiction questionnaire (2012), Solomon and Rothblum’s academic procrastination questionnaire (1984), Sun, Dunne, Hou and Xu’s academic stress scale (2011), and Pittsburgh’s sleep quality scale (1989) and the mark average of previous term for measuring academic achievement. Data were analyzed by using Pearson correlation and structural equation modeling. Results showed that social network addiction has an indirect negative effect on academic achievement through creating academic procrastination, decreasing sleep quality and increasing academic stress. Increased use of social network increases procrastination among students and spending excessive amounts of time in these networks reduces quality of sleep that both of them, in turn, increase academic stress which leads to dropout.
