Instead of using scale thresholds and standard diagnostic criteria, latent class analysis was used to elucidate distinct subgroups of adolescents based on symptom profiles of the 24 Youth Self-Report items assessing attention-deficit hyperactivity, oppositional and conduct problem behaviors. We then investigated the extent to which being classified into different classes of disruptive behavior was associated with drug consumption in the month prior to the survey assessment. Three latent classes of disruptive behavior emerged along a continuum of severity. Youth classified into a class representing multiple and more serious behavior problems were found to have the highest rates of drug use, particularly involving inhalants and marijuana. Contrary to our hypotheses, younger adolescent females in this class reported a higher rate of past month drug use than similarly aged males. Drug use also was found to be common among youth in a class with a greater proportion of subclinical levels of behavior problems. Adolescents evidencing multiple behavior problems, particularly emerging conduct problems, need to be thoroughly assessed for recent drug involvement.
本研究未使用量表阈值和标准诊断标准，而是采用潜在类别分析，根据评估注意力缺陷多动、对立和行为问题的24项青少年自评项目的症状概况，阐明青少年的不同亚组。然后，我们调查了在调查评估前一个月被归类为不同破坏性行为类别与药物消费之间的关联程度。破坏性行为的三个潜在类别沿着严重程度连续体出现。被归类为代表多种更严重行为问题类别的青少年，其药物使用率最高，尤其涉及吸入剂和大麻。与我们的假设相反，该类别中年龄较小的青少年女性报告的过去一个月药物使用率高于同龄男性。在行为问题亚临床水平比例较高的类别中的青少年中，药物使用也很常见。有多种行为问题，尤其是新出现的行为问题的青少年，需要对其近期药物使用情况进行全面评估。
