 Abstract 

Objective: This pilot cohort case study evaluates the empirical efficacy of a brief trauma-focused group intervention based on Advanced Integrative Therapy (AIT) to help women survivors of intimate partner violence (IPV) suffering from posttraumatic stress disorder (PTSD) and dissociative symptoms. 

Methods: The research employed an intragroup design with pre- and post-treatment measurements taken before and two months after the intervention. The sample consisted of 12 women, all of whom had experienced IPV and clinical symptoms of PTSD. The Revised PTSD Symptom Severity Scale-Revised (EGS-R) served as the assessment instrument. The group International Journal of Healing and Caring 2025, 25(1) 11-33 

treatment consisted of 15 structured sessions, organized into four core components and two integrative elements. 

Results: Post-treatment assessments indicated a significant reduction in all DSM-5 criteria subgroups, with 91.66% of participants moving out of the clinical category. 

Conclusions: This case study provides compelling evidence supporting the efficacy of group AIT treatment in alleviating PTSD and associated dissociative symptoms among female IPV survivors. As more evidence on AIT accumulates, exploring its potential applicability in public institutions and nongovernmental organizations is warranted.
