Background:  Non-suicidal self-injury (NSSI) has become one of the key health problems in the field of adolescent psychology. So far, there is a research gap regarding the efficacy of process-based therapy in reducing clinical symptoms in this group of people and comparing its efficacy with cognitive behavioral therapy
 Aims: The aim of this study was to compare the efficacy of process-based therapy and cognitive-behavioral therapy on clinical symptoms of girls with a history of non-suicidal self-injury.
Methods: The method was a quasi-experimental pretest-posttest design with two experimental groups and a control group and a two-month follow-up. The statistical population of the study included all adolescent girls aged 13 to 18 with a history of self-injury who referred to the Counseling and Psychological Services Center of the Management Education District 2 Mashhad of Mashhad in 2024, From among them, 45 people were selected using purposive sampling and assigned to two experimental groups (process-based therapy and cognitive-behavioral therapy) and a control group. Research data were also collected using the Inventory of Statements About Self-injury (Klonsky & Glenn, 2009) and Depression, Anxiety and Stress Scales (Lovibond & Lovibond, 1995). Also, to analyze the research data, the variance analysis with repeated measurement and the Bonferroni post hoc test and SPSS-27 software were used.
Results: The results showed that both process-based therapy and cognitive-behavioral therapy are effective in reducing clinical symptoms in girls with a history of non-suicidal self-injury (P<0.01), but there is no significant difference between these two types of treatment (P<0.05). The results of the Bonferroni post hoc test also indicated that the effects of both types of treatment continued during the follow-up period
Conclusion:it is recommended that therapists who deal with this group of adolescents use these treatment methods to treat and prevent self-injury and suicide in adolescents.
