What this trial studies

This study investigates the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy for individuals with Substance Use Disorders (SUD) who have also experienced trauma. The research aims to address the often-overlooked connection between psychological trauma and SUD, which can hinder recovery and lead to high relapse rates. Participants will undergo EMDR therapy alongside treatment as usual (TAU) to evaluate improvements in their condition. The study will include adults aged 18 to 65 with a primary diagnosis of moderate to severe SUD and current posttraumatic symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with a primary diagnosis of moderate to severe substance use disorder and a history of traumatic experiences.

Not a fit: Patients who have received trauma-focused therapy in the last 5 years or have severe dissociative symptoms may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve treatment outcomes for patients with substance use disorders by addressing underlying trauma.

How similar studies have performed: While EMDR has shown promise in treating PTSD and other disorders, its application in substance use disorders is still limited and not extensively tested.
