  1. The demographic variables of gender, education, and race were controlled for in each multivariate model.
  2. The following variables are not presented in the table because they were not significant in any model: deployment status, mild traumatic brain injury symptoms, and mental health care stigma.
  3. Dashes indicate that variable was not retained in the final model because its association was not statistically significant.
  4. CI, confidence interval; OR, odds ratio; PTSD, posttraumatic stress disorder.
  5. **p < .01; *p < .05; †p < .10.
