Respondents were classified as seeking lifetime mental health treatment for PTSD or AD, if they: (1) visited a counselor, therapist, doctor, or psychologist; (2) were a patient in a hospital for at least one night; (3) visited an emergency room; or (4) were prescribed medications. Treatment utilization questions were disorder-specific. Moreover, the past 12 months treatment-seeking rates were also compared among individuals with PTSD only, AD only and PTSD-AD.
