The percentage of "523,626 female and male active duty Sailors and Marines who entered the U.S. military between 2006 and 2013" who had a PTSD diagnosis, according to a recent article in the Journal of Traumatic Stress -- Prevalence of Posttraumatic Stress Disorder and Psychological Comorbidities Among U.S. Active Duty Service Members, 2006–2013.
Among those with a PTSD diagnosis, 83.3% were diagnosed with a comorbid mental health disorder, and 62.2% had a third (trimorbid) disorder.
Most frequently, PTSD co‐occurred with depressive disorder (49.0%), adjustment disorder (37.0%), generalized anxiety disorder (36.1%), and alcohol use disorder (26.9%). All disorders we examined were significantly more likely to be diagnosed in service members with PTSD than in those without PTSD, odds ratios = 1.52–29.63. For service members with PTSD, comorbid mental health disorders are the rule rather than the exception. Consequently, it is important that clinicians also assess for other disorders and select treatment options that address both PTSD and comorbid conditions.
