National Comorbidity Survey: Adolescent Supplement (NCS-A), 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身和当前患病率、发病年龄分布、病程和共病情况，以DSM-IV诊断标准评估；识别导致这些疾病发病和持续的风险和保护因素；描述这些疾病的诊疗模式和相关性；并为后续的追踪研究奠定基础，以识别成人精神疾病的早期表现。NCS-A的核心访谈日程是对世界卫生组织综合国际诊断访谈（CIDI）的改编。此外，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，还从家长或家长替代者那里收集信息，以获取青少年心理健康及其相关因素的额外视角。家长提供的信息主要集中在五种青少年疾病上，因为这些疾病在先前的方法论研究中，家长报告已被证明对诊断至关重要：注意力缺陷多动障碍、品行障碍、对抗性违抗障碍、重度抑郁发作和抑郁症。NCS-A收集的人口统计信息包括年龄、公民身份状态、出生国、犯罪记录、种族、祖父母出生国、家庭中使用的语言、父母出生国、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）回答长自填问卷的家长的数据；（3）回答长自填问卷和简短电话访谈的家长的数据；（4）从青少年和家长收集的数据中衍生出的诊断变量；（5）按NCS-A青少年样本规范化的K-BIT分数；（6）原始K-BIT数据。
