Externalising disorders are some of the most prevalent problems in childhood and particularly during adolescence that can change into more severe psychopathology in adulthood if left unattended. In the research literature, these disorders include attention deficit/hyperactivity disorder, oppositional/defiant disorder, conduct disorder and substance use disorders. The comorbidity prevalence of these disorders is significant and cannot be considered a random factor. The dimensional structure of psychopathology has always been studied by researchers to address disorder comorbidities and aetiology. There has always been controversy over the number of spectra and the lower levels. Currently, the new top-down, Hierarchical Taxonomy of Psychopathology model conceptualising psychopathology is being used, which is a dimensional classification system for the different spectra of psychopathology based on a combination of conceptual modelling and factor analysis of symptoms. This systematic review investigates the comorbidity prevalence of spectra of externalising disorders to provide valuable information and feedback on this model.
This systematic review will include all the studies conducted from 1/1/1990 to 1/12/2020 to examine the prevalence and comorbidity of each of the externalising disorders in the general population, schools and outpatients using any instrument (questionnaires or interviews). There will be no language restrictions in selecting the studies. The studies are age restricted and must be conducted on adolescents only, but there are no restrictions on the gender and nationality of the participants.
This systematic review is based on previously published articles and therefore will not require ethical approval. The results of the systematic review will be disseminated as publication in a peer-reviewed journal and conference presentation.

外化障碍是儿童期最常见的问题之一,尤其是在青春期,如果不加治疗,这些问题可能会发展为更严重的精神病理学问题。在研究文献中,这些障碍包括注意力缺陷/多动障碍、对立/反抗障碍、品行障碍和物质使用障碍。这些障碍的共病患病率很高,不能被视为随机因素。精神病理学的维度结构一直是研究人员研究障碍共病和病因的重点。关于谱的数量和低层次,一直存在争议。目前,新的自上而下的、精神病理学层级分类模型正在被使用,这是一种基于概念模型和症状因子分析相结合的精神病理学不同谱的维度分类系统。本系统评价调查了外化障碍谱的共病患病率,为该模型提供了有价值的信息和反馈。
本系统评价将包括所有在 1990 年 1 月 1 日至 2020 年 12 月 12 日期间进行的研究,以检查一般人群、学校和门诊中外化障碍各谱的患病率和共病情况,使用任何仪器(问卷或访谈)。在选择研究时,不会有语言限制。研究的年龄限制是必须在青少年中进行,但对参与者的性别和国籍没有限制。
本系统评价是基于以前发表的文章进行的,因此不需要伦理批准。系统评价的结果将作为同行评议期刊的发表和会议报告进行传播。
