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.

国家共病调查复制青少年补充调查（NCS-A）旨在估算美国青少年在生命至今的终生及当前患病率、发病年龄分布、病程及共病情况，以识别这些疾病的发病和持续风险及保护因素；描述这些疾病的服务使用模式及其相关性；并为后续追踪研究奠定基础，以识别成年期精神疾病的早期表现。核心NCS-A访谈日程是对世界卫生组织综合国际诊断访谈（CIDI）的改编。NCS-A还实施了考夫曼简明智力测验（K-BIT）的非言语子测试（矩阵子测试）。除了对青少年进行访谈外，还从父母或父母替代者处收集信息，以获得青少年心理健康及其相关性的额外视角。父母提供的信息集中在以下五种青少年疾病上，既往方法论研究表明，父母报告对于诊断这些疾病至关重要：注意力缺陷/多动障碍、品行障碍、对立违抗障碍、重度抑郁发作和心境恶劣。NCS-A收集的人口统计信息包括年龄、国籍状态、出生国家、犯罪记录、民族、祖父母出生国家、家庭中使用的语言、父母的出生国家、种族、宗教和性别。数据收集包含六个数据文件：（1）青少年家庭和学校受访者的数据；（2）对长篇自我管理问卷做出回应的父母的资料；（3）对既回答长篇自我管理问卷又回答简短电话访谈的父母的资料；（4）从青少年和父母收集的数据中派生的诊断变量；（5）规范至NCS-A青少年样本的K-BIT分数；（6）原始K-BIT数据。
