Purpose: This study examined how participation in the Service Platoon program of The Mission Continues (TMC) impacts self-reported purpose in life (PIL), interpersonal support (IS), and civic engagement (CE) among military veterans. Methods: An online survey was given to military veterans upon initial registration with TMC and again 12 months later (n=395). The survey assessed Service Platoon program participation rates, as well as demographic factors, PIL, IS, and CE. Linear regression models were estimated to determine the effect of Service Platoon participation on change scores for PIL, IS, and CE. Results: Posttest scores on all measures were higher at higher levels of event participation, although differences in scores were modest. Conclusions: Results showed that females with participation in seven or more events had significant increases in IS from pretest to posttest, b=4.56 (95% CI=0.44, 8.68). Recommendations: We recommend social networking programming that works to improve interpersonal support and community connectivity among veterans.
