摘 要：The purpose of this project is to help prevent psychological disorders in high-risk individuals with early symptoms of stress, depression, substance use, and other health problems. Military medicine is increasingly concerned with the incidence of psychological casualties and the treatment of post-traumatic stress disorder (PTSD) in returning personnel. This incidence increases the need for medical care and reduces operational readiness. Few preventive methods are available to mitigate subclinical psychological health issues upon the return of personnel from deployment. The PHIT for Duty system is a personal health intervention tool (PHIT) using mobile smartphone technology to integrate personal health assessment with targeted self-help intervention for the mitigation of psychological symptoms, modification of risky behaviors, and provision of cognitive support. The study will identify self-help interventions to assist individuals in dealing with combat and operational stress; develop smartphone applications for health assessment and self-help intervention; and evaluate the PHIT methodology for prevention of psychological disorders in post-deployed personnel. Improvements in patient- related outcomes are expected to be demonstrated in 2-3 years. The PHIT for Duty mobile health approach can be transitioned for chronic disease management, obesity prevention, substance use intervention, and other domains where better personal health management could improve wellness and clinical outcomes.
