First-Line Intervention for PTSD - Intensive Treatment

The goal of this clinical trial is to learn if an intensive program can treat post-traumatic stress disorder (PTSD) in adults getting treatment for the first time, and whether it has lower societal costs. The main questions it aims to answer are: * Does an intensive program reduce PTSD symptoms? * How expensive is it on a societal level? Researchers will compare the intensive program to the standard weekly treatment to see if the intensive program works to treat PTSD. Participants will: * Get 5 days of intensive treatment in two weeks (with two preparatory and closing sessions), or weekly sessions * Get questionnaires and interviews 5 times in 9 months
