Social anxiety Disorder is one of the most common anxiety disorders in the clinical sample. So far, many methods have been used to improve and treat this disorder, among which interventions based on acceptance and commitment are one of the most effective methods.
The present study was conducted with the aim of meta-analyzing the effect of interventions based on acceptance and commitment on social anxiety disorder and resolving possible contradictions in the results of different studies. The statistical population of this research included the researches conducted in the field of the effectiveness of interventions based on acceptance and commitment on social anxiety during the last 20 years in Iran (1380-1401) and international levels (2000-2022).
Based on the defined entry and exit criteria, 40 studies that had appropriate scientific and methodological conditions were selected to enter the meta-analysis. The results showed that the average size of the combined effects of the fixed model is -0.874 and that of the random model is -1.234, both of which are statistically significant. This shows the positive effect of interventions based on acceptance and commitment on social anxiety.
Therefore, it can be concluded that by using interventions based on acceptance and commitment, the amount of social anxiety in people can be reduced.
