Computerized Tailored Intervention for Behavioral Sequelae of Post-Traumatic Stress Disorder in Veterans
In Brief
A clinical study evaluating Multibehavioral, Computerized Tailored Intervention STR2IVE for Post Traumatic Stress Disorder and 3 related conditions. Completed, enrolled 90 participants across 3 sites.
Detailed Summary
This project assesses the usability and feasibility of a multi-behavioral computerized, tailored intervention (CTI) or expert system delivered via the Internet for veterans with Post-Traumatic Stress symptoms. Three behavioral health risk factors, (1) smoking, (2) depression, and (3) stress, that are associated with Post-Traumatic Stress Disorder (PTSD), are included in the Computerized, Tailored Intervention (CTI) system. The project adapts and modifies an existing CTI system built on the Transtheoretical Model of Behavior Change (TTM) to make it relevant to a veteran population. The system has been successfully utilized with general adult populations. The study utilizes methods that are characteristic of a product development project. Each of the four project phases are sequential and build upon the results of the previous phase. Phase 1 focuses on the review of current CTI programs on smoking cessation, stress management, and depression prevention, and integrating them into a multi-behavioral program for application with veterans. Phase 2 includes the development and adaptation of text-based feedback messages and multimedia components for smoking cessation, stress management, and depression prevention for veterans. Initial testing of the modified CTI programs commences in Phase 3. Cognitive and usability testing with veterans are performed, and additional modifications to the behavioral modules are made based on the test results. Phase 4 focuses on a feasibility study to test the multi-behavioral CTI system with veterans online.

Timeline
Interventions
All participants were provided with the same multibehavioral CTI system and chose two or three behavior programs to complete (smoking cessation, stress management, and/or depression prevention)monthly. They were asked to complete an assessments at baseline, 30-days, and 90-days. They were allowed to access the system workbook anytime but they must wait a minimum of 25 days between assessments and programs at time points 1 and 2, and 55 days between time points 2 and 3.
