What this trial studies

This clinical trial aims to evaluate the effectiveness of Massed Prolonged Exposure Therapy (M-PE) for veterans suffering from PTSD and substance use disorders. Participants will receive either multiple therapy sessions per week or weekly sessions while enrolled in intensive outpatient substance use treatment. The study seeks to determine if the massed format improves PTSD symptoms and reduces substance use compared to traditional weekly sessions. By focusing on veterans who have served since September 2001, the trial addresses a critical need for effective treatment strategies in this population.

Who should consider this trial

Good fit: Ideal candidates include veterans aged 18 and older who have served since September 2001 and are enrolled in a substance use intensive outpatient program.

Not a fit: Patients with severe cognitive impairment or those currently experiencing suicidal or homicidal intent may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve PTSD treatment outcomes and reduce substance use among veterans.

How similar studies have performed: Previous studies have shown that massed formats of therapy can enhance treatment outcomes in military and veteran populations, indicating a promising approach.
