Research: the IMPACT study
We aim to evaluate three types of treatments for adults with Childhood Abuse related Post-Traumatic Stress Disorder (CA-PTSD): prolonged exposure (16 sessions in 16 weeks), intensified prolonged exposure (12 sessions in 4 weeks and 2 booster sessions) and phase based treatment (8 sessions emotion regulation and interpersonal skills training with STAIR followed by 8 sessions prolonged exposure in 16 weeks). We will investigate the reduction in PTSD symptoms and other PTSD related symptomatology, the cost-effectiveness of the treatments and differences in dropout between the treatments. Additionally, we will investigate whether there are patient characteristics which are related to the effectiveness of the treatment.
