Older military Veterans are at elevated risk for social disconnection, which confers risk for a variety of negative physical and mental health outcomes and mortality. Multiple aspects of Veteran status and culture can contribute to loneliness and social disconnection, including adjustment from military to civilian life, high rates of physical and mental comorbidities, limited resources, history of combat exposure and trauma, experience of loss and grief, and stigma around help-seeking and social roles. The importance of building social connection and support for Veterans has been recognized in several countries, with U.S. Veterans Affairs and community-based organizations implementing programs to link Veterans with support. Older Veterans can be assessed for social disconnection with measures that are validated in older adults and that consider these unique facets of Veteran status, to inform care that fosters connection. Interventions should address idiosyncratic social connection needs and barriers and be accessible in a way that reduces stigma.
