Background & Aims: Social networks are now being created as an admission to search, discuss and share information interactive and immediate with others. The purpose of this study was to model the role of emotional resilience and self-resilience in the tendency of addiction to social networks mediated by psychological well-being. The use of social networks has become a modern natural behavior, but the harmful forms of their use have also received much attention in the last two decades. Social networks have now emerged as a platform for searching, discussing and sharing information interactively and instantly with others. Their popularity, especially among young people, has led to a significant increase in research into the analysis of the consequences of their use. Has been in the psychosocial development of users. Social networks have provided various facilities for users, but their uncontrolled, uninformed and excessive use of them creates dangers for users in families. Social networks are a source of attention in personal, academic and professional work. In the context of academia, they can lead to academic procrastination and undermine students' academic performance. One of the psychological characteristics of students that is affected by the use of social networks is emotional resilience. Previous studies have shown that psychological characteristics such as resilience may predict cell phone addiction and social networking. Resilience, as a complex, dynamic and multidimensional phenomenon, can be thought of as a process, capacity or consequence of positive adaptation and continuous professional commitment and growth in the face of challenging conditions. Emotional resilience should be considered as a person's ability to cope with adversity and overcome failure. Emotional resilience requires a high degree of self-awareness, strong self-regulation, and a host of other characteristics. Factors such as stress, burnout, lack of social support and negative thinking are the enemies of emotional resilience. Another variable that can be associated with social media addiction is self-concealment. In the literature on psychology and counseling, selfconcealment is often defined as the tendency to intentionally conceal personal information that one finds disturbing or negative. Self-concealmentis a behavioral tendency in which individuals hide personal information about distress, embarrassment, and negativity from others. One of the most important structures that play a mediating variable in social network addiction is psychological well-being. Psychological well-being is one of the structures studied in positivist psychology. Today, a new perspective is being formed and expanded in healthrelated sciences in general and in psychology in particular, with the aim of focusing on health. It is drawn from individual life to social interactions. In general, according to the above research records, the dispersion and contradiction of research in the field of social media addiction and the lack of studies in Iran, highlights the need for further implementation and research in this field. In addition, the mobile phones of this technological tool, which are especially popular among the younger generation, have led to lifestyle changes, differentiation of social interaction styles, as well as preparing them to limit their lives in the technological world. This in itself highlights the need for such research. Therefore, the present study aim to model the role of emotional resilience and self-concealment in the tendency of addiction to social networks mediated by psychological well-being. Methods: The method of the present study is descriptive and correlational and the method of analysis is structural equation modeling. The statistical population of the present study was all students studying at Mohaghegh Ardabili University. Since the PLS method is not sensitive to the sample size, the required sample size was determined using Barclayo et al.'s (1995) theory for the present study (32). However, in order to achieve more generalizable results and less statistical error in the sample size in the present study, considering the probability of sample loss, 200 people were considered. After removing the distorted data, 120 questionnaires were included in the statistical analysis. Sampling method used Sampling was also available. The questionnaires were designed online and its links were provided to the subjects on social networks (Telegram groups and channels, WhatsApp groups and Instagram pages) so that students who wished to participate in the research could answer the questions. Inclusion criteria were willingness to participate in research and being a student and exit criteria were unwillingness to participate in research. The data collected in this study were analyzed using descriptive statistical tools such as mean and standard deviation and structural equation modeling using SPSS.25 software and 3.smart pls software. Results: A total of 120 students with a mean age of 28.75 and a standard deviation of 8.71 participated in this study.The results showed that emotional resilience and self-deprecation had a direct and significant effect on social networking addiction, as well as the indirect effect of emotional resilience and self-deprecation with the mediation of psychological well-being (t > 1.96). Conclusion: The results of structural equations showed that emotional resilience has a direct and significant relationship with addiction to social networks. Explaining these results, it can be said that resilience can be generally defined as the ability to adapt to adverse situations in a positive way. Adolescents with lower resilience are more likely to become addicted to social media and in challenging situations instead the use of positive coping strategies tends to lead to negative behaviors such as social media addiction. The results of structural equations showed that self-concealment has a direct and significant relationship with addiction to social networks. Explaining these findings, it can be said that adolescents who have high self-conceit may become addicted to social networks to escape the negative feelings related to selfconcealment. The results of structural equations showed that psychological well-being has a direct and significant relationship with addiction to social networks. Explaining these findings, it can be said that according to the negative consequences of addiction to social networks, psychological well-being can prevent adolescents' addiction to social networks. Described over time.The results of structural equations showed that emotional resilience on social media addiction has an indirect and significant relationship with the mediation of psychological wellbeing. In explaining these findings, it can be said that, as stated earlier, resilience refers to the factors and processes that protect physical development and psychological well-being from the risk of engaging in problematic behaviors and psychological damage. The results of structural equations showed that self-denial on social media addiction is indirectly and significantly related to psychological well-being. Many people who have selfdeprecation turn to the Internet to manage and get rid of unwanted self-deprecating feelings such as stress, loneliness, depression and anxiety. They see the Internet as the easiest way out of these feelings, which is the starting point for Internet addiction. Emotional resilience and self-deprecation can show different functions of social networking in students. Therefore, examining the role of psychological well-being mediates provides more accurate information on the impact of these variables for various social network addiction. [ABSTRACT FROM AUTHOR]
