The prevalence of DAA/HCD or ADHD in young adult prison inmates is significantly elevated when compared to nondelinquent controls. Generally the population of young adult male prison inmates exhibits a considerable psychiatric morbidity. Of the total sample, 64% suffered from at least 2 disorders. Only 8.5% had no psychiatric diagnoses. This indicates the urgent need for more psychiatric expertise in young offender facilities.

We report on the development of a German self-rating behaviour questionnaire (ADHD-SR) and diagnostic checklist (ADHD-DC) for the diagnosis of attention-deficit/hyperactivity disorder in adults according to DSM IV and ICD 10 research criteria. When comparing self-rating with expert rating, we found good concordance measured by intraclass coefficients on the level of single symptoms and syndrome scores. High retest reliability of the ADHD-SR demonstrated the ability to assess time-stable behaviour traits. Evaluation of the psychometric properties revealed good internal consistency and adequate convergent and divergent validity measured by the "big five" derived from the NEO-FFI and the constructs impulsivity, venturesomeness, and empathy of Eysenck's impulsiveness questionnaire. We detected a remarkable correlation with the Wender Utah Rating Scale, which targets the detection of childhood ADHD symptoms. Diagnostic sensitivity for different cutoff points was calculated by ROC analysis at 65--88%. Specificity was 67% to 92%.

There is considerable evidence that attention deficit/hyperactivity disorder (ADHD) is associated with conduct problems, social maladaptation and delinquent behavior. The "Ottweiler Study" was performed to elaborate the prevalence of ADHD and comorbid disorders in 129 young adult detainees of the juvenile prison of Ottweiler (Germany) according to DSM-IV and ICD-10 criteria. Here we report psychopathological characteristics of 28 inmates, who fulfilled the diagnostic criteria for persisting ADHD, and 37 individuals with neither a history nor current ADHD symptoms. Childhood ADHD symptoms but no current ADHD were present in 64 individuals. The Wender-Reimherr Interview (WRI) based on the Utah criteria for adult ADHD, the NEO-five factor personality inventory (NEO-FFI) and the youth self report/young adult self report (YSR/YASR) according to Achenbach were used for the assessment of psychopathology and the description of behavioral problems. Regarding WRI and YSR/YASR we found a significant increase of emotional and internalizing problems in the ADHD group compared to delinquents without ADHD or ADHD history. ADHD delinquents scored higher on the personality dimension neuroticism, and showed lower scores on the dimensions agreeableness and consciousness. Using discriminant analysis, high scores on the WRI subscales disorganization and attention difficulties and NEO-FFI neuroticism were the best predictors of ADHD diagnosis. The results support prior findings of high ADHD prevalence in prison inmates and suggest that emotional and internalizing abnormalities are prominent problems in this population. Further studies are needed to elucidate the role of ADHD as an independent factor for life-persistent criminality, since specific treatment may help to ameliorate the legal prognosis.

Diagnosing attention deficit hyperactivity disorder (ADHD) in adults requires retrospective assessment of ADHD symptoms in childhood. The Wender Utah Rating Scale (WURS) and its German validated version (WURS-k) may offer a helpful tool to acertain relevant childhood problems associated with ADHD. Up to now validating data of the WURS-k were limited to male population. In a population of 69 female adult ADHD patients and 97 controls, ROC analysis indicated a sensitivity of 93% and specificity of 92% at a cut-off of 30 points in the WURS-k. This cut-off value is equivalent to those of males. Symptom report varies significantly by gender and females describe more internalizing problems while males report more externalizing behaviour. Regarding different subtypes according to DSM-IV males and females did not differ in the items of the WURS-k.
