OBJECTIVE To test the previously suggested hypothesis that those with comorbid ADHD and Conduct Disorder (CD) diagnoses differ from other antisocially involved youth in terms of higher rates of violent behavior, impulsiveness, and psychopathic traits. METHOD Three hundred eighty juvenile incarcerated delinquents from Northern Russia were assessed by means of semi-structured psychiatric interview and by student and teacher self-reports. RESULTS The study has demonstrated higher rates of psychiatric disorders and of comorbidity, as well as more complicated substance abuse and disruptive behaviors in those with combined ADHD-CD diagnosis, as compared with CD only, ADHD only, and no CD no ADHD groups. The results regarding psychopathic traits were inconclusive. CONCLUSION The group with combined ADHD-CD diagnosis is more severely disturbed, both as concerns psychiatric comorbidity and more severe aggressive and disruptive behaviors. However, there is only limited evidence supporting a higher prevalence of psychopathic traits in this group.

俄罗斯多动症和品行障碍的男性青少年犯罪者的合并症和行为特征。

目的为了检验先前提出的假设，即患有多动症和行为障碍（CD）合并症的人与其他反社会参与的年轻人在暴力行为，冲动和精神病特征的发生率方面有所不同。方法通过半结构性精神病学访谈和学生和老师的自我报告，评估了来自俄罗斯北部的380名少年被监禁的犯罪者。结果：与仅CD，仅ADHD和无CD无ADHD组相比，合并ADHD-CD诊断的患者精神病和合并症的发病率更高，药物滥用和破坏性行为更为复杂。关于精神病性状的结果尚无定论。结论合并ADHD-CD诊断的人群受到的干扰更大，既涉及精神病合并症，也涉及更严重的侵略性和破坏性行为。但是，仅有有限的证据支持该组中精神病性状的较高患病率。
