Effect of Multiple Behavioural Therapy on Dissociative Symptoms Among Patients with Dissociative Disorder: A Preliminary Study

Background: Dissociative symptoms are commonly observed in individuals with dissociative disorders and are associated with emotional dysregulation, identity disturbance, and maladaptive coping. These symptoms pose significant challenges in clinical management and often require structured psychotherapeutic interventions. Aim: The present study aimed to examine the effectiveness of Multiple behavioural Therapy (MBT) in reducing dissociative symptoms among patients diagnosed with Dissociative Disorder. Methods: A single-group pre–post intervention design was employed. Ten female patients diagnosed with Dissociative Disorder participated in a six-month MBT program. Dissociative symptoms were assessed using the Dissociative Experiences Scale–II (DES-II) before and after the intervention. Paired-sample t-tests were conducted to evaluate treatment-related changes. Results: Results indicated a statistically significant reduction in dissociative symptoms following the MBT intervention (p < .001), suggesting a substantial therapeutic effect. Conclusion: Findings suggest that Multiple behavioural Therapy may be an effective intervention for reducing dissociative symptoms. Further controlled studies with larger samples are recommended.
