Structural Model of psychological Well-being based on Basic Psychological Needs and Mindfulness With the Mediating role of Problematic internet Use in adolescents

The current study aimed to provide a structural model of psychological well-being based on basic psychological needs and mindfulness with the mediating role of problematic internet use in adolescents. By applying the structural equation modeling (SEM) approach. The population comprised all male and female high school students in Kashan in the academic year 1401-1402 in the number of 6470 people, of which according to Morgan's table, a sample of 325 people were selected by available sampling. Then, the Psychological well-being scale (RSPWB) Ryff (1989), the Psychological Needs Satisfaction scale (BNSG-S) Guardia, Deci & Ryan (2000), Mindful Attention Awareness Scale (MAAS) Brown, Ryan (2003) and the Internet Addiction Test (IAT) Young (1998) were completed by participants. Data analysis was performed using the path analysis method and Bootstrapping method was used to examine the mediating role of problematic internet use. The results showed that the direct path of Psychological needs and mindfulness to problematic Internet use and psychological well-being had a significant effect (p<0.05). Moreover, Psychological needs and mindfulness with the mediation of problematic Internet use had a significant indirect effect on psychological well-being (p<0.05). The fit index also showed that the default model has a good fit. Therefore, it can be concluded that problematic internet use plays a mediating role in the relationship between Psychological needs and Mindfulness with adolescents' psychological well-being.
