This study will enroll behavioral health providers (i.e., professional therapists) and test a training program for Written Exposure Therapy that includes
1. an enhanced, web-based foundational training (web-based training plus integrated TherapyTrainer components) and
2. an AI training support tool for competency development (TherapyTrainer).
This randomized clinical trial will compare web/AI training, among providers who serve Veterans and Service Members, to standard Written Exposure Therapy training (i.e., human-delivered live workshop and consultation calls) on provider, patient, and cost-effectiveness outcomes. There is no cross-over of conditions. Providers in both conditions will be eligible to earn continuing education credits and approval as Written Exposure Therapy Providers who have completed competency based training and two training cases.
