TraumaRelief App: A Pilot RCT Assessing Feasibility and Acceptability

Participants in the therapist-supported group will receive weekly 20-30 minute online sessions for five weeks, with content based on a semi-structured manual. After 80% completion of the psychoeducation module, the coping module becomes available, and similarly, the exposure module follows. These sessions will be conducted in adherence to a structured manual, with the therapist introducing the module of the week, guiding through exercises, assigning homework, and reviewing the previous assignments. Sessions include module introductions, exercises, homework assignments, and application use review. Feedback and PCL-5 scores guide post-session recommendations. A random 40% of sessions will undergo fidelity checks by doctoral-level psychologists.

"Participants allocated to this group will have access to the TraumaRelief mobile application over a five-week period, with the exception of the online module component. The application's deployment strategy ensures a structured progression through its features: participants will gain access to the subsequent modules only after completing 80% of the preceding module. Initially, they will engage with the psychoeducation module; upon completion of at least 80% of this module, the coping with symptoms module will become available. Similarly, successful engagement with 80% of the coping module will unlock the imaginary exposure module. This sequential module access is designed to reinforce the acquisition of knowledge and skills in a stepwise manner, paralleling the structure provided to the TraumaRelief Mobile Application with Therapist Support group, yet without the additional therapist interaction."
