ABSTRACT
This study aimed to model PIU (Problematic Internet Use) based on executive functions, interpersonal needs, depression, and fear of missing out in adolescents aged 15 to 19 residing in Tehran. The sample size included 200 girls and boys selected through convenience sampling. Participants completed the computerized Wisconsin Card Sorting Test, Young’s Internet Addiction Test (IAT), Beck Depression Inventory (BDI-II), Fear of Missing Out scale (FOMOS), and Interpersonal Needs Questionnaire (INQ). The data were analyzed using structural equation modeling with SPSS 26 and AMOS 24 software. According to the results, executive functions directly and through the mediating effects of depression and the fear of missing out, predicted PIU. Thwarted belongingness through the mediating effect of depression and the fear of missing out had an effect on PIU. Perceived burdensomeness predicted PIU directly and indirectly through the mediating effect of depression. The relationship between perceived burdensomeness and fear of missing out was not significant in this study. Overall, the fit indices indicated that the proposed research model is a good fit, and executive functions, depression, interpersonal needs, and fear of missing out can predict PIU. Moreover, executive functions, thwarted belongingness, and perceived burdensomeness were able to predict depression, and executive functions, along with thwarted belongingness, could predict fear of missing out.
