AIM: This study aimed to investigate the prevalence of attention-deficit/hyperactivity disorder (ADHD) in adult psychiatric outpatients. Moreover, comorbid psychiatric diagnoses in adults with ADHD were determined. Patients with and without ADHD were compared regarding DSM Axis I-II comorbidity and sociodemographic characteristics. MATERIALS AND METHODS: The study included patients that presented for the first time to a psychiatric outpatient clinic during a 3-month period and were evaluated for adult ADHD. A sociodemographic form, Wender Utah Rating Scale, Turgay's Adult ADD/ADHD Evaluation Scale, Structured Clinical Interview I and II, Symptom Check List-90-R, and Beck Depression Inventory were administered. RESULTS: The study included 246 patients. Among the 39 patients diagnosed with ADHD, 25 were female (64.1%) and 14 were male (35.9%), and the mean age was 27.38 ± 8.3 years. The prevalence of ADHD in adult psychiatric patients was 15.9%. Adults with ADHD usually presented due to comorbid psychiatric problems; major depression (43%), generalized anxiety disorder (23%), and obsessive-compulsive disorder (17%) were the most common comorbid diagnoses. Substance abuse (58.9%) and attempted suicide (38.5%) were among the most prevalent psychiatric problems. CONCLUSION: The present findings show that ADHD is an important comorbidity in adult patients that present to psychiatric clinics, and may cause serious mental health problems or complicate mental illness.
