ADAPT-PTSD Study aims to help veterans with PTSD (Post-Traumatic Stress Disorder) who aren't getting better from their first treatment. PTSD is a mental health condition triggered by a scary event. This study explores new ways to help by changing treatments and using reminders to complete tasks between therapy sessions.

• The study lasts multiple sessions and involves trying different treatments.
• Participants receive text message reminders to help complete therapy tasks.
• Only veterans with a mobile device can join, as a special app is needed for therapy.

To join, veterans must be 18 or older and have a PTSD score of 31 or higher. Participants should not have severe mental health issues like unmanaged psychosis or bipolar disorder. Also, they shouldn't have had similar treatments recently. The study uses a special design to find the best treatment methods, and it's done in regular healthcare settings for veterans. This research could help tailor treatments specifically for each person, leading to better results.
