In the past decade, the military has deployed approximately 1 million members into combat, and a factor that plagues the military veterans returning from combat is the prevalence of posttraumatic stress disorder (PTSD). A factor to examine is preparedness training before combat because the research has shown that postcombat resilience training has been effective in reducing symptoms of PTSD. Using the social cognitive theory, the purpose of this study was to determine whether self-reported preparedness training before deployments was related to lower severity of self-reported PTSD. Based on prior research, age and gender are other variables that this study examined. Participants were a sample population of veterans who completed a quantitative survey, which included demographics, the Posttraumatic Stress Disorder Check List, and the Training and Deployment Preparation survey, Section H of the DRRI-2. Data collected from the survey were input into the SPSS program and analyzed using multiple linear regressions. Results reflected that preparedness training had an inverse correlation relationship to self-reported PTSD severity, age had a predictive relationship, and gender did not show a significant relationship. It appears that preparedness training for combat does help reduce self-reported severity of PTSD in veterans returning with PTSD symptoms. Providing preparedness training before combat may help in reducing this phenomenon. The results of the present study, developing procedures and therapeutic measures to help veterans in need can be generalized into the mainframe of social and behavioral change for all individuals dealing with PTSD, including first responders
