Straus E, Norman SB, Tripp JC, et al. - This study attempted to explore the current prevalence of loneliness, and the relation between loneliness severity and psychiatric and physical health conditions, suicidality, and functional measures in a predominantly older sample of U.S. military veterans. Between November 2019 and March 2020, researchers designed a cross-sectional study using data from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of U.S. veterans (N=4,069; mean age=62). Valid and reliable self-report assessments were used to assess a comprehensive range of psychiatric, physical health, and functioning variables. The findings suggested that in U.S. military veterans, loneliness is highly prevalent, with more than half endorsing feeling lonely sometimes or often, and 1-of-5 reporting feeling lonely often. It was shown that loneliness severity was independently correlated with a broad range of psychiatric and functional measures, including suicidal ideation. The outcomes demonstrate the importance of loneliness as a transdiagnostic prevention and intervention target in the U.S. veteran population.
