Differential associations of adverse childhood experiences and mental health outcomes in U.S. military veterans.

Adverse childhood experiences (ACEs) are robustly associated with adverse mental health outcomes across the lifespan. Military veterans may be particularly vulnerable to adverse mental health effects of ACEs given their potentially higher prevalence of childhood traumas and compounding effects of military service-related traumas. To date, however, scarce research has examined the differential impact of individual ACEs on mental health outcomes in population-based samples of veterans. To address this gap, we analyzed data from the National Health and Resilience in Veterans Study (NHRVS), which surveyed a nationally representative sample of 4069 U.S. veterans, to examine the association between specific ACEs and major depressive, generalized anxiety, and posttraumatic stress disorders, and suicidal thoughts and behaviors. Results of multivariable logistic regression analyses revealed that emotional neglect and sexual abuse were most consistently associated with these outcomes, even after adjustment for the number of ACEs endorsed. Collectively, results of this study underscore the importance of assessing for specific ACEs-most notably childhood emotional neglect and sexual abuse-and treating these potentially unresolved childhood traumas in veterans.
