The study aimed to achieve the primary objective of identifying the effectiveness of dialectical behavior therapy (DBT) in reducing socially aggressive behavior among university students. The secondary objectives of the treatment program using DBT are achieved through sessions designed to reduce socially aggressive behavior toward oneself, reduce socially aggressive behavior toward others, and reduce socially aggressive behavior toward public and private property.
This study falls within the scope of studies that measure the return on professional intervention, using a quasi-experimental design (single-case design). The study sample consisted of (10) university students at the Faculty of Social Work, Assiut University. A situation assessment form, content analysis of data and information from each student's file, and content analysis of professional interviews were used.
The study results demonstrated the effectiveness of the professional intervention program (DBT) in reducing socially aggressive behavior among university students. The overall effect size was 0.89, a high effect size indicating that 89% of the change is attributable to the program. The results also showed that the program contributed to reducing all three dimensions of aggression. The greatest improvement occurred in the dimension of aggression toward oneself, with a change rate of 40.91%, followed by aggression toward others, with a change rate of 40.34%, and then aggression toward property, with a change rate of 36.88%.
The study results also confirmed the validity of the main and sub-hypotheses, as statistically significant differences were found between the repeated measures (A - B - A2 - B2) in the total score on the social aggression scale, as well as in its three dimensions, confirming the clear and effective impact of the treatment program.
