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.

    Examination of the mental health symptoms and stigmatizing attitudes of student servicemembers and Veterans in postsecondary education

    Abstract:Student servicemembers and veterans (SSM/V) face challenges when transitioning from military service into higher education, including mental health concerns and difficulties with academic and social adjustment. This study examined mental health symptoms, adjustment to college, stigma, and help-seeking attitudes among 79 SSM/V enrolled in postsecondary education. Participants completed measures related to depression (PHQ-8), anxiety (GAD-7), posttraumatic stress (PCL-5), adjustment to college (VAC), self-stigma (SSOSH), public stigma (SSRPH), and attitudes toward seeking professional psychological help (ATSPPH-SF). Results indicated that average scores reflected mild levels of depression, anxiety, and posttraumatic stress. Veterans reported significantly higher levels of depressive and PTSD symptoms compared to active-duty servicemembers. Number of deployments was negatively correlated with adjustment scores. Race and ethnicity were found to be significant predictors of help-seeking attitudes. Although college adjustment was negatively correlated with depression, anxiety, and PTSD symptoms, the findings did not reach statistical significance, perhaps due to the limited variability in the sample. Most participants reported generally positive attitudes toward mental health services, though both self-stigma and perceived public stigma were present. Service utilization was high overall, with 76% of participants reporting prior mental health service use and 44% who were currently engaged in treatment at time of survey completion. Findings underscore the importance of addressing cultural factors, deployment experiences, and stigma to improve adjustment, retention, and well-being among SSM/V in postsecondary education.
