BACKGROUND: U.S. military veterans frequently experience exposure to trauma and multiple co-occurring physical health and psychiatric conditions that can impair functioning. Nonetheless, some veterans maintain higher-than-expected levels of functioning despite these adversities, a pattern reflecting functional resilience. Identifying modifiable factors associated with such resilience may inform interventions to support optimal functioning in this population.
METHODS: Data were analyzed from 4069 participants in the National Health and Resilience in Veterans Study, a nationally representative survey of U.S. veterans. Four domains of functioning-physical, mental, cognitive, and psychosocial-were combined via exploratory factor analysis to derive a composite functioning score. Functional resilience was operationalized using a discrepancy-based residual approach, in which the composite functioning score was regressed onto measures of trauma exposure and physical and mental health burden. Positive residuals represented better-than-expected functioning given trauma- and health-related burden. Bivariate, multivariable, and relative importance analyses were conducted to identify sociodemographic, psychosocial, and personality correlates of functional resilience.
RESULTS: A single latent factor accounted for 60.5 % of the variance across functioning domains. Mindfulness, grit, and perceived resilience were the strongest correlates of functional resilience, jointly explaining over 75 % of the total explained variance. Additional independent correlates included conscientiousness, physical exercise, positive expectations about aging, and community integration. Older age and being married or partnered were also associated with higher functional resilience.
CONCLUSIONS: Modifiable psychosocial traits and health behaviors are strongly associated with functional resilience among U.S. veterans. Interventions that enhance mindfulness, grit, perceived resilience, and positive attitudes toward aging may help promote better functional outcomes in this population.
