Background and Purpose: Recent studies show that adolescents showing psychopathic behaviors experience difficulties in interpersonal reactivity. So, the present study aimed to compare the effectiveness of Multisystemic Therapy (MST) and Schema Therapy (ST) based on mothers' training on interpersonal reactivity in adolescent girls with psychopathic behaviors.
Method: This quasi‑experimental study employed a pretest-posttest method, including two experimental groups and one control group. The statistical population consisted of all tenth- and eleventh-grade students from four public high schools for girls in Karaj City during the 2023–2024 academic year. From a total of 520 students, thirty adolescents with psychopathic behaviors—identified using a cut-off score of 27 on the Levenson Self-Report Psychopathy Scale—were selected through convenience sampling and randomly assigned to three groups (10 participants in each group). The first experimental group received twelve weekly sessions of MST, while the second experimental group took part in twelve weekly group sessions of ST. Meanwhile, the control group continued to receive the regular educational programs provided by their school. Data collection tools included the Self-Report Psychopathy Scale (LSRPS; Levenson, 1995) and the Davis Interpersonal Reactivity Questionnaire (DIRQ; Davis, 1983). Data were analyzed using multivariate analysis of covariance (MANCOVA) and Bonferroni post-hoc tests with SPSS- 24.
Result: The findings showed that both MST and ST based on mothers' training were effective in improving interpersonal reactivity compared to the control group (P<0/001). However, MST had a greater effect than ST in enhancing interpersonal reactivity among adolescent girls with psychopathic behaviors (P<0/001).
Conclusion: Based on the results, MST is a more effective approach for addressing the psychological consequences in students with psychopathic behaviors. Therefore, these interventions can be used as complementary methods alongside other therapeutic and preventive programs. |
