Loneliness and Social Isolation of Military Veterans: Systematic Narrative Review
Abstract: Loneliness and social isolation are being increasingly recognized as influencing both physical and mental health. There is limited research carried out with military veterans and, to date, there is no review of existing evidence. To synthesize and examine the evidence exploring aspects of social isolation and loneliness of military veterans, using a systematic narrative review strategy. A database search was carried out utilizing relevant search criterion. Seven databases were searched for publications with no date restrictions. Articles were included if they involved veterans and either social isolation or loneliness. The initial search returned 484 papers, after exclusions, removal of duplications, and a reference/citation search, 17 papers remained and were included in this review. The retrieved papers examined four areas of loneliness and social isolation: prevalence of loneliness in the veteran population, experiences related to military service as impacting loneliness or social isolation, the relationship between mental health and loneliness or social isolation, and interventions to combat loneliness and social isolation. Differences between the experiences of younger and older veterans were also highlighted. It is evident that military veterans present unique experiences of loneliness and social isolation, especially older veterans. This requires specific attention outside of campaigns targeted at the nonmilitary population.
Abstract: Objective: The present study is a retrospective quasi-experimental study to evaluate the effectiveness of the Warrior PATHH (WP) program at improving posttraumatic growth (PTG) outcomes and reducing PTSD symptoms compared to a waitlist control among a sample of Veterans. Method: Participants (n = 164) were U.S. military Veterans with a history of trauma. Participants were either undergoing the Warrior PATHH program or a waitlist. Primary outcome measures were administered at baseline and at 90-day follow-up and consisted of the Posttraumatic Growth Inventory – Expanded (PTGI-X) and the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5). Secondary outcome measures assessed psychosocial functioning and included measures of depression and anxiety symptoms, sleep, wellbeing, and social support. Results: Significant differences were observed between groups on the PTGI-X (F(1, 205) = 23.667, p < .001, partial η2 = 0.103), and the PCL-5 (F(1, 205) = 262.460, p < .001, partial η2 = 0.561) with the WP group showing significant positive psychological change following a traumatic event as measured by the PTGI-X and decreased PTSD symptoms as measured by the PCL-5 compared to those in the waitlist condition. Those in the treatment arm also demonstrated gains to psychosocial functioning. Conclusions: Consistent with previous research, participants in the Warrior PATHH program exhibited significant increases in PTG outcomes, decreased PTSD symptoms, and broad improvements to psychosocial functioning. These findings suggest it is an effective training program to foster PTG outcomes among Veterans. This study is unique as it is the first to compare the effects of WP programming with a sample of waitlisted Veterans.
