Abstract
|
BACKGROUND: Dissociative symptoms have been documented in diverse clinical and non-clinical populations, and are associated with poor mental health outcomes. Yet, research on dissociative symptoms is frequently limited to PTSD samples, and therefore little is known about the prevalence, clinical correlates, and risk factors related to dissociative symptoms in broader, representative trauma-exposed populations.
METHODS: The current study assessed dissociative symptoms in a contemporary, nationally representative sample of trauma-exposed U.S. veterans irrespective of PTSD diagnostic status. We then compared sociodemographic, military, and psychiatric characteristics, trauma histories, level of functioning, and quality of life in veterans with dissociative symptoms to those without dissociative symptoms; and determined the incremental association between dissociative symptoms, and suicidality, functioning, and quality of life, independent of comorbidities.
RESULTS: A total 20.8% of U.S. veterans reported experiencing mild-to-severe dissociative symptoms. Compared to veterans without dissociative symptoms, veterans with dissociative symptoms were younger, and more likely to be non-white, unmarried/partnered and unemployed, had lower education and income, and were more likely to have been combat-exposed and use the VA are their primary source of healthcare. They also had elevated rates of psychiatric comorbidities, lower functioning and quality of life, and a 5-fold greater likelihood of current suicidal ideation and 4-fold greater likelihood of lifetime suicide attempt history. LIMITATIONS: Cross-sectional data limit inference of the directionality of findings, and results may not generalize to non-veteran populations.
CONCLUSIONS: Dissociative symptoms are prevalent in U.S. veterans and may be an important transdiagnostic marker of heightened risk for suicidality and psychiatric comorbidities. These results underscore the importance of assessing, monitoring, and treating dissociative symptoms in this population.
