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; 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 the NSS Regular Army and NSS Guard/Reserve at the .05 level, two-sided test. Only one disorder differed significantly in mean persistence (IED) and another in proportional persistence (BPD) across samples.
Proportion of years with recurrence is the ratio of number of years in episode beyond the year of onset to total number of years since onset.
Persistence of attention-deficit/hyperactivity disorder is not assessed by the CIDI screening scales and is thus excluded from this table
