Note. AUD/SUD=Alcohol or Substance Use Disorder; CI=confidence interval; PTSD=posttraumatic stress disorder; MDE=major depressive episode; GAD=generalized anxiety disorder; SI=suicidal ideation. Each column displays the results for a separate weights-adjusted logistic regression model. To streamline the table, soldier characteristics included in the models (age, sex, race, ethnicity, education, and marital status) are omitted; none displayed significant associations with incidence or persistence of AUD/SUD (ps>.10). Models also adjusted for Brigade Combat Team. Significant adjusted odds ratios (where the overall Wald X2 test is also statistically significant) appear in bold.

Chronic AUD/SUD was defined as the disorder being present at both 3 months and 9 months post-deployment (i.e., at both T2 and T3).
