Past research investigating the structure of conduct disorder (CD) symptoms has provided evidence of a phenotypic distinction between aggressive and rule-breaking subfactors of CD. However, evidence of etiologic distinctions between these subfactors has not been reported to date. In the current study, the authors investigated this issue in a sample of 1,151 male twins who were 17 years of age. The results indicate that aggressive and rule-breaking CD subfactors have both common and distinct etiologic influences, with shared environmental influences playing a significant role in rule-breaking behaviors. The authors discuss implications of these findings for the assessment and treatment of CD.
过去对品行障碍(CD)症状结构的研究已经提供了证据,证明CD的攻击性行为和违反规则亚因素之间存在表型差异。然而,迄今为止尚未报告这些亚因素之间病因差异的证据。在当前的研究中,作者在1151名17岁男性双胞胎样本中调查了这个问题。结果表明,攻击性行为和违反规则的CD亚因素具有共同和不同的病因影响,共同环境影响在违反规则行为中发挥着重要作用。作者讨论了这些发现对CD评估和治疗的意义。
