The purpose of this research is to compare the effectiveness of metacognitive therapy, solution-oriented therapy, and endurance exercises on the problem-solving styles of female students with social anxiety disorder. The design of this research is a semi-experimental pre-test-post-test type with a heterogeneous control group and a one-month follow-up. The statistical population was female students of the second level of high school in the three educational districts of Kermanshah in the academic year 1401-1402. From this population, 60 students with social anxiety were selected by screening and according to the criteria for entering the study. They were randomly assigned to 4 groups of 15 people (three experimental and one control). The research tools included social anxiety questionnaires (Kanor, 2000) and problem-solving styles (Dzurila et al., 2002). The data were analyzed with SPSS23 software and analysis of variance and Benferoni's post hoc test. The findings showed that metacognitive therapy, solution-oriented therapy, and endurance exercises increased efficient problem-solving styles and decreased ineffective problem-solving styles in people with social anxiety (P≤0.05) and among the three treatments, metacognitive therapy in efficient problem-solving styles and metacognitive and solution-oriented treatment in ineffective problem-solving styles were more effective than endurance exercises (P≤0.05). Based on these findings, it can be said that all three treatment models can be used in the Iranian clinical sample.
