Plain Language Summary 
Panic, stress, and avoidance of social relationships are social panic or anxiety, which should be investigated attentively. When it prevents daily tasks, this disorder becomes a social disorder. Acceptance and commitment therapy (ACT) is a good treatment method for stress. This approach has been found as a part of the third generation of psychotherapeutic interventions, and it tries to treat the mental relationships of people with their ideas and sentiments rather than transforming them. So, this research was performed to assess the impact of ACT and psychodrama therapy on nurses’ social anxiety. Our randomized trial research was performed at Torbat Heydarieh University of Medical Sciences in 2017 with a pre-test-post-test design. The number of participants was 48. They were randomly selected from nurses with a social anxiety disorder (SAD) referred to the university counseling center and entered into 4 groups with 12 members in each group (an intervention group and 3 control groups). The intervention group received a combination of psychotherapeutic therapies and participated in twelve 90-minute treatment sessions (2 meetings every week). The control groups were provided therapy based on psychodrama, ACT, and no treatment. Data collection was done by Connor’s social anxiety questionnaire (2000). Data analysis was done by analyses of variance and covariance. Considering the social anxiety prevalence in society, especially among nurses, and the complications caused by it for the progress of people and society, taking this disorder into account and finding a more successful approach to treat it seems necessary. Although separately using psychodrama therapy and ACT has been publicized to have an important impact on SAD symptoms, the use of the two approaches together intensifies their powerful impacts even more. So, individuals participating in psychological health, like psychotherapists, are recommended to apply this protocol to treat the disorder of social anxiety of clients, their life quality, and social interactions.
