Introduction Attention-defi cit hyperactivity disorder (ADHD) affects not only children, but persists in up to 4.4% of the general population. Comorbidity is common am ong adults with ADHD, including substance abuse. To our knowledge, the relation between ADHD and substance-use disorder (SUD) has not been studied in Arab countries thoroughly. Aim of the work The aim of this study was to estimate the prevalence rate of adult ADHD among substanceuse inpatients and to compare substance use in patients with and without adult ADHD with regard to the onset, the severity, and the type of substance of abuse. Participants and methods This cross-sectional comparative study was conducted at the Addiction Treatment Center at El Maamoura psychiatric hospital. One hundred and two adult male inpatients were recruited and assessed using a semistructured interview questionnaire to collect sociodemographic data, substance-use history, and medical and psychiatric history. The psychiatric interview was applied, and psychometric assessment was performed using the Arabic version of the Wender Utah Rating Scale, which examined retrospectively the symptoms of childhood ADHD, and the Arabic version of the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist for screening for adult ADHD. Results Thirty-six (35.3%) patients were diagnosed as having adult ADHD according to DSM-IV-TR criteria. The presence of adult ADHD was associated with an earlier mean age of onset of SUD (15.58 vs. 13.22 years). It was also associated with a larger number of hospital admissions (6.83 vs. 3.39 times). Individuals with ADHD achieved a shorter mean period of abstinence (124.53 vs. 209.82 days). Conclusion This study confi rmed the presence of adult ADHD among substance-use patients with a considerable prevalence rate. Also, the presence of adult ADHD was associated with a more complicated course of SUD.
