Abbreviations: DSM-IV, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition; Army STARRS, Army Study to Assess Risk and Resilience in Servicemembers; SE, standard error; NSS, New Soldier Study; NCS-R, National Comorbidity Survey-Replication; MDE, major depressive episode; BPD, broad spectrum bipolar disorder; GAD, generalized anxiety disorder; PD, panic disorder; PTSD, post-traumatic stress disorder; IED, intermittent explosive disorder; CD, conduct disorder; ODD, oppositional defiant disorder; SUD, substance use disorder; ADHD, attention deficit hyperactivity disorder.
Significant difference between NSS and NCS-R (within the total sample, Regular Army, and Guard/Reserve samples) at the .05 level, two-sided test.
Six individual disorders were significantly more prevalent in the NSS Guard/Reserve than the NSS Regular Army at the .05 level, two-sided test: MDE, GAD, PD, PTSD, IED, ADHD. Rates of any internalizing disorder, any lifetime disorder, and exactly 1 lifetime disorder were also significantly more prevalent in the NSS Guard/Reserve than the NSS Regular Army. CD was the only disorder that was significantly more prevalent in the NSS Regular Army than the NSS Guard & Reserve.
Prevalence rates in the NCS-R Regular Army and NCS-R Guard/Reserve did not significantly differ from one another at the .05 level, two-sided test.
ADHD symptoms were assessed in the NSS only over the past six months, while they were assessed for childhood in the NCS-R and only respondents who met criteria during childhood were then assessed for the past six months. Thus, imputed ADHD was used to estimate rates in the NCS-R.
