What this trial studies

This study investigates the effectiveness of prolonged exposure therapy for treating post-traumatic stress disorder (PTSD) in patients who also have a comorbid psychotic disorder. It aims to determine whether this trauma therapy can reduce PTSD and psychosis symptoms compared to a Treatment-As-Usual Waiting Group. The study is a multicenter, controlled, prospective, randomized trial, focusing on the severity of PTSD symptoms over a six-month follow-up period. Secondary outcomes include assessments of paranoia and hallucinations.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a confirmed diagnosis of PTSD and a schizophrenia spectrum disorder who have been experiencing distressing auditory hallucinations for at least six months.

Not a fit: Patients with acute suicidality, recent changes in medication, or substance addiction may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly improve the quality of life for patients suffering from both PTSD and psychotic disorders.

How similar studies have performed: Previous studies have shown promising results for trauma therapy in similar patient populations, indicating potential for success in this approach.
