Attention-deficit/hyperactivity disorder in young French male prisoners.

While forensic studies have reported higher than community rates of mental disorders in imprisoned populations, few studies have focused on attention-deficit/hyperactivity disorder (ADHD) in these subjects. The aim of this study was to investigate ADHD prevalence among young French male prisoners. A specific diagnostic interview (Conners' Adult ADHD Diagnostic Interview for DSM-IV, CAADID) was used. Correlations between ADHD, subsyndromal ADHD, and criminal features were investigated. 11% of young male prisoners among 93 male subjects aged 18-35 years met the criteria for actual ADHD, and 17% met those for childhood ADHD. Considering ADHD and subsyndromal ADHD, prevalence was about 43% in adulthood. ADHD and subsyndromal ADHD in adulthood were significantly associated with a higher number of imprisonments and a younger age at first arrest. It could be advisable to better identify subjects with ADHD symptoms among prison populations.
