Abstract: (216 Views)
Background: In adolescents, inability to cope with social situations and engage in adolescent stress and pressures has been largely attributed to an inability to regulate emotions, and this inability can even manifest as non-suicidal self-harm in adolescents. Given that the source of vulnerability for behaviors such as non-suicidal self-harm is partly due to an inability to regulate emotions, integrative transdiagnostic therapy claims to place emotion regulation as a transdiagnostic factor at the heart of intervention.
Aims: The present study aimed to investigate the effectiveness of group training based on unified transdiagnostic treatment on emotion regulation and non-suicidal self-harm in adolescent girls.
Methods: The research method was a quasi-experimental design with a pretest-posttest design and a control group with a two-month follow-up period. The statistical population of the study included female adolescents in the tenth and eleventh grades of the Kar and Danesh branch of Arak city in 2024. The sample size consisted of 51 people (control group 26 people, and experimental group 25 people) who were selected through purposive sampling and randomly placed in two groups. The research instruments included the Difficulty in Emotion Regulation Scale (Gertz & Romer, 2004) and the Self-Harm Inventory (Sanson et al., 1998). The unified transdiagnostic treatment group (Barlow et al., 2017) received 12 one-hour intervention sessions. The control group did not receive any intervention. Data were analyzed using repeated measures analysis of variance in SPSS version 27.
Results: The results showed that the Wickls Lambda statistic for examining the interaction effect between group and time in the research variables was significant (P<0.001) and that integrative transdiagnostic therapy had a significant effectiveness on emotion regulation and non-suicidal self-harm compared to the control group (P<0.05), and these results were maintained in the follow-up phase.
Conclusion: It is suggested that psychologists and therapists use group training based on the integrative transdiagnostic method as an effective method for improving emotion regulation and non-suicidal self-harm. Also, counselors and psychologists at student counseling centers can use integrative transdiagnostic therapy to improve emotion regulation and non-suicidal self-harm problems
