Background and Aim: One of the psychological problems of students is social phobia, which can greatly reduce academic performance. The present study was conducted with the aim of Investigating the role of self-compassion, self-esteem and trait anger in predicting social phobia of female adolescent students.

Method: This study is descriptive and was conducted using the correlational method. The study population consisted of high school students in Arak during the academic year 1401-1402. The sample size was determined as 250 individuals based on the Green formula and sampling was done cluster sampling. Participants responded to the Social Anxiety Scale by Conover and colleagues (2000), Rosenberg's Self-Esteem Scale (1965), Self-Compassion Scale by Raes and colleagues (2011), and Spielberger's State-Trait Anger Expression Inventory (1990). The data was analyzed using Pearson correlation and multiple regression methods at a significance level of 0.05, and the analysis was conducted utilizing SPSS26 software.

Results: The results indicate a significant negative relationship between feelings of self-esteem and social anxiety (p<.001). Furthermore, there is a significant negative relationship between self-compassion and social anxiety (p<.001), and a significant relationship between trait anger and social anxiety exists as well (p<.001). Multiple regression analysis revealed that 25% of the variance in social anxiety among adolescent students is predicted by a linear combination of the variables of self-compassion, self-esteem, and trait anger (R =.512, R2=.462, adjusted R2=.451).

Conclusion: self-compassion-based interventions grounded in self-esteem and proper anger management and assertiveness can help reduce social anxiety by modifying mood, temperament, and angry reactions towards mistakes.
