What this trial studies
This clinical trial aims to compare a novel intensive treatment format of prolonged exposure therapy with the standard weekly prolonged exposure therapy for adults suffering from post-traumatic stress disorder (PTSD). Participants will be randomly assigned to either receive the intensive treatment over 5 days with follow-up booster sessions or the traditional weekly sessions over 15 weeks. The study will evaluate the efficacy, mechanisms of change, and cost-effectiveness of the intensive approach in regular psychiatric care in Sweden. The goal is to determine if the intensive format can improve retention rates and recovery times for patients with PTSD.
Why it matters
Potential benefit: If successful, this study could lead to a more effective and efficient treatment option for adults with PTSD, potentially reducing dropout rates and speeding up recovery.
How similar studies have gone: Preliminary research has shown that intensive trauma-focused treatment approaches can be as effective as traditional methods, suggesting potential success for this novel comparison.
