National Comorbidity Survey: Adolescent Supplement (NCS-A), [United States], 2001-2004

The National Comorbidity Survey Replication Adolescent Supplement (NCS-A) was designed to estimate the lifetime-to-date and current prevalence, age-of-onset distributions, course, and comorbidity of DSM-IV disorders in the child and adolescent years of life among adolescents in the United States; to identify risk and protective factors for the onset and persistence of these disorders; to describe patterns and correlates of service use for these disorders; and to lay the groundwork for subsequent follow-up studies that can be used to identify early expressions of adult mental disorders. The core NCS-A interview schedule was an adaptation of the World Health Organization Composite International Diagnostic Interview (CIDI). NCS-A also administered the non-verbal subtest (Matrices subtest) of the Kaufman Brief Intelligence Test (K-BIT). In addition to interviewing adolescents, information was collected from a parent or a parent surrogate to obtain an additional perspective on the adolescent's mental health and its correlates. Information from parents focused on the five adolescent disorders for which previous methodological research has most consistently shown that parental reports are important for making diagnoses: attention-deficit/hyperactivity disorder, conduct disorder, oppositional defiant disorder, major depressive episode, and dysthymic disorder. Demographic information collected by NCS-A includes age, citizenship status, country of birth, criminal history, ethnicity, grandparents' country of birth, language(s) spoken in the home, parents' country of birth, race, religion, and sex. The data collection contains six data files: (1) data for the adolescent household and school respondents; (2) data for the parents who responded to the long self-administered questionnaire; (3) data for the parents who responded to both the long self-administered questionnaire and short telephone interview; (4) diagnostic variables derived from the data collected from the adolescents and parents; (5) K-BIT scores normed to the NCS-A adolescent sample; and (6) raw K-BIT data.

全国共病调查复刻版青少年补充调查（National Comorbidity Survey Replication Adolescent Supplement, NCS-A）旨在评估美国青少年群体在儿童及青少年阶段，《精神障碍诊断与统计手册（第四版）》（Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, DSM-IV）所定义障碍的终生累计患病率与当前患病率、发病年龄分布、病程及共病情况；识别此类障碍起病与持续存在的风险及保护因素；阐明此类障碍的精神卫生服务使用模式与相关关联因素；并为后续用于识别成人精神障碍早期表现的追踪研究奠定基础。NCS-A的核心访谈问卷改编自世界卫生组织复合式国际诊断访谈（World Health Organization Composite International Diagnostic Interview, CIDI），同时还施测了考夫曼简易智力测验（Kaufman Brief Intelligence Test, K-BIT）的非言语分测验（矩阵分测验）。除对青少年进行访谈外，研究团队还向家长或家长代理人收集信息，以获取青少年心理健康状况及其相关因素的额外观测视角。家长提供的信息聚焦于5类青少年精神障碍——既往方法学研究一致证实，父母报告对这类障碍的临床诊断具有重要价值，分别为注意缺陷/多动障碍、品行障碍、对立违抗障碍、重性抑郁发作以及心境恶劣障碍。NCS-A收集的人口统计学信息包括年龄、公民身份、出生国家、犯罪记录、族裔、祖父母出生国家、家庭使用语言、父母出生国家、种族、宗教信仰与性别。本次数据采集共包含6个数据文件：(1) 青少年家庭与学校受访者数据；(2) 填写过长式自填问卷的家长数据；(3) 既填写过长式自填问卷又完成简短电话访谈的家长数据；(4) 由青少年与家长调研数据衍生得到的诊断变量数据；(5) 以NCS-A青少年样本为常模的K-BIT得分数据；(6) 原始K-BIT数据。
