Fittness the causal-structural relationships of self-efficacy and self-regulation with Internet addiction with the mediation of quality of life in adolescents in Tehran.

The present study was conducted with the aim of examining the causal-structural relationships of self-efficacy and self-regulation with Internet addiction, with the mediation of quality of life among teenagers in Tehran.

The research design is descriptive-retrospective correlation. A total of 314 teenagers were selected from the teenagers of Tehran city using available sampling method. The data were collected using Young's Internet Addiction Questionnaire, Warosherbon's 36-item Quality of Life Questionnaire, Beaufard's Self-Regulation Questionnaire, and the Self-Efficacy Questionnaire of Mauritian Children and Adolescents. The data were analyzed using the structural equation modeling method in AMOS-Graphic software version 24.

All research variables except self-regulation had a significant negative relationship with Internet addiction. The path coefficients indicated the appropriate fit of the model in which both quality of life (directly) and self-efficacy (indirectly through quality of life) predicted Internet addiction. The direct paths of quality of life with Internet addiction, self-regulation with self-efficacy are significant at the level of significance (α<0.01) and self-efficacy with quality of life are significant at the level of significance (α<0.05). The results for the direct paths of self-efficacy with Internet addiction, self-regulation with Internet addiction and self-regulation with quality of life were not significant (α>05). Also, the indirect effect of self-efficacy on Internet addiction through the mediation of quality of life was confirmed (α<0.05) and the indirect effect of self-regulation on Internet addiction through the mediation of quality of life was rejected (α>0.05). Conclusion Quality of life and self-efficacy play a key role.
