The study aimed to analyze the effectiveness of self-compassion training on recurrent negative thinking and psychological distress in students’ victims of bullying. A quasi-experimental study was carried out with pretest/posttest measures and a control group. The sample of participants was obtained in 2023 among male secondary school students in the city of Tabriz (Iran). Fifty students who were victims of bullying were selected as participants and were randomly divided into the experimental group and the control group. The experimental group received 8 sessions of self-compassion training over two months, one 90-minute session per week. All participants completed the evaluation instruments in pre-test and post-test. Data were analyzed using multivariate analysis of covariance. The results showed that self-compassion training had a significant effect on reducing the components of psychological distress and negative thinking (p <.001), reducing anxiety, depression, and negative thoughts after self-compassion training.
