Abstract

Negative mental health outcomes are prevalent among veterans exposed to military-related stressors and are associated with social isolation. Limited research exists on resilience following military separation and its impact on social isolation in veterans. We examined resilience against military-related stressors and 2-year longitudinal associations with social isolation indicators; gender differences were also explored. U.S. military veterans (N = 351, 70.4% men) who deployed to the wars in and around Iraq and Afghanistan following the September 11, 2001, terrorist attacks (9/11) were recruited as part of a longitudinal assessment study examining predictors of postdeployment adjustment. Using a residualization approach, resilience was approximated as low stressor reactivity (SR), calculated by regressing mental health onto military-related stressor exposure. Military-related stressors were significantly associated with posttraumatic stress disorder (PTSD) related to both events during post-9/11 deployment (deployment event) and outside of post-9/11 deployment (other event), functional disability, and depression. After correcting for multiple comparisons, only SR derived from depressive symptoms predicted more closeness difficulties in social relationships longitudinally, B = 0.50, q = .023. Women also demonstrated higher SR than men regarding other event-related PTSD symptoms, B = -0.52, q < .001; functional disability, B = -0.28, q = .028; and depression, B = -0.34, q = .012. Results suggest that veterans with higher depressogenic reactivity to military-related stressors were more likely to endorse discomfort with closeness than those with lower depressogenic reactivity. Women veterans may also be more impacted by nondeployment traumatic distress, psychosocial dysfunction, and depression in response to military-related stressors.
