Read our PTSD research guide →This study is following about 50 people who have both a substance use disorder and a trauma-related diagnosis. Some participants will have PTSD (post-traumatic stress disorder), while others will have Complex PTSD (a more severe form that usually develops from trauma in childhood). All participants will receive standard addiction treatment and trauma-focused therapy, and researchers will track how well each group improves over 10 weeks.
About one in three people struggling with substance use also have trauma-related diagnoses, but doctors aren't sure whether one type of trauma diagnosis leads to different treatment outcomes than the other. This study aims to understand whether Complex PTSD makes recovery more difficult than regular PTSD when both conditions are treated together.

You would receive addiction treatment and trauma-focused therapy as part of your regular care — both proven approaches used in Dutch clinics. Researchers would ask you to complete brief assessments at the start, after each trauma therapy session, and again 10 weeks later to measure how your symptoms change. The study lasts about 10 weeks, and all treatment is provided to you regardless of which group you're in.
