This study was conducted with the aim of investigating the moderated role of basic psychological needs by family cohesion in the relationship between shyness and mobile phone dependency among girl adolescents. This is descriptive correlational research. The studied population included all girl adolescents aged 13 to 18 who were student in Tehran in 1401, 283 people were selected as a sample using convenience sampling method, and responded to the Revised Cheek and Buss Shyness Scale (Cheek, 1983), Mobile Phone Addiction Index (Leung, 2008), Basic Psychological Needs Scale (Deci & Ryan, 2000) & Family Organized Cohesiveness Scale (Fisher et al., 1992). Pearson correlation and multiple regression by installing Hayes macro-Process (model 4 & 59) in SPSS24 were used to analyze the data. The results showed that basic psychological needs mediate the relationship between shyness and mobile phone dependency, and the relation of shyness with mobile phone dependency and basic psychological needs, as well as the relationship between basic psychological needs and mobile phone dependence, is moderated by family cohesion. Based on this, by increasing the satisfaction of basic psychological needs in adolescents and increasing family cohesion, their shyness and as a result their dependence on mobile phones will decrease. These findings are useful for understanding the complex mechanism of shyness effects on mobile phone dependency and have practical implications for preventing and reducing adolescents' mobile phone dependency.
