Comparing different therapeutic approaches in psychology can help therapists identify their time, cost, and effectiveness; Therefore, the present study was conducted to compare the effectiveness of Gestalt coaching training and treatment based on acceptance and commitment on controlling of Tehran Telecommunication Company employees.

The research method was quasi-experimental with pre-test, post-test and follow-up with control group. The statistical population included all employees of Perso Electronic Telecommunication Company in Tehran in 1398, from which according to Cohen's table, 45 people were selected by relative random sampling and randomly divided into two experimental groups and a control group. The research instruments included Taghizadeh Tendency to Control Others Questionnaire (1396). The experimental groups underwent Gestalt coaching training and acceptance and commitment treatment. Data were analyzed by repeated measures and ANOVA test.

There was a significant difference between the effectiveness of Gestalt coaching training with acceptance and commitment-based treatment on reducing control (P ≤ 0.001). The effectiveness of gestalt training in both post-test and follow-up was more effective than acceptance and commitment therapy (P ≤ 0.001).

Based on the findings, it can be concluded that Gestalt coaching training and treatment based on acceptance and commitment can be a good way to reduce staff control.
