The impact of posttraumatic growth, transformational leadership, and self-efficacy on psychological symptoms among combat veterans
Previous research has established self-efficacy and posttraumatic growth as essential to post-deployment adjustment among veterans, and perceived transformational leadership is well known for its positive effects on follower outcomes across contexts. However, little is known regarding how transformational leadership may relate to self-efficacy and posttraumatic growth in fostering psychological wellbeing among combat veterans. The purpose of this dissertation was to examine the role of posttraumatic growth and transformational leadership in predicting PTSD and depression symptoms among combat veterans, as well as how post-deployment coping self-efficacy may mediate these relations. Regression analysis revealed post-deployment coping self-efficacy and perceived transformational leadership as predictors of fewer psychological symptoms. In addition, mediation modeling using bootstrapping resampling revealed that post-deployment coping self-efficacy mediated the relation between transformational leadership and both PTSD and depression. These findings may aid in the prediction of PTSD and depression symptoms among veterans, which may then influence pre-deployment leadership training among military personnel as well as clinical treatment protocols for veterans.
