the effectiveness of dialectical behavior therapy on self-injury and impulsive behaviors in twelfth-grade students

The present study aimed to investigate the effectiveness of dialectical behavior therapy (dbt) on self-injury and impulsive behaviors among 12th-grade male students. the research employed a quasi-experimental design with a pretest-posttest and control group. the statistical population included all 12th-grade students in isfahan county. based on inclusion criteria, 34 students were selected through convenient non-random sampling and were randomly assigned to experimental and control groups (17 participants in each group). data were collected using the self-harm inventory (shi) and the barratt impulsiveness scale (bis-11). the experimental group received 10 weekly dbt sessions (each lasting 60 minutes), while the control group remained on a waiting list. data were analyzed using univariate and multivariate covariance analysis (ancova and mancova) in spss-26 software. the findings revealed that group dbt had a significant effect on reducing self-injury and impulsive behaviors among students (p < .001). the effect sizes for impulsive behaviors and self-injury were .693 and .435, respectively. based on the results, dialectical behavior therapy can be considered an effective intervention approach for reducing high-risk behaviors among adolescents. the present study aimed to investigate the effectiveness of dialectical behavior therapy (dbt) on self-injury and impulsive behaviors among 12th-grade male students. the research employed a quasi-experimental design with a pretest-posttest and control group. the statistical population included all 12th-grade students in isfahan county. based on inclusion criteria, 34 students were selected through convenient non-random sampling and were randomly assigned to experimental and control groups (17 participants in each group). data were collected using the self-harm inventory (shi) and the barratt impulsiveness scale (bis-11). the experimental group received 10 weekly dbt sessions (each lasting 60 minutes), while the control group remained on a waiting list. data were analyzed using univariate and multivariate covariance analysis (ancova and mancova) in spss-26 software. the findings revealed that group dbt had a significant effect on reducing self-injury and impulsive behaviors among students (p < .001). the effect sizes for impulsive behaviors and self-injury were .693 and .435, respectively. based on the results, dialectical behavior therapy can be considered an effective intervention approach for reducing high-risk behaviors among adolescents.
