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.

美国全国共病调查复本青少年补充调查（NCS-A）旨在估算美国青少年群体中，儿童及青少年时期《精神疾病诊断与统计手册》第四版（DSM-IV）所列障碍的终身患病率（截至调查时）与当前患病率、发病年龄分布、病程及共病情况；识别这些障碍发生与持续存在的风险因素及保护因素；描述这些障碍的服务使用模式及其相关因素；并为后续随访研究奠定基础，这些研究可用于识别成人精神障碍的早期表现。NCS-A的核心访谈方案改编自世界卫生组织复合性国际诊断访谈问卷（CIDI）。NCS-A还实施了考夫曼简明智力测验（K-BIT）的非言语分测验（矩阵分测验）。除访谈青少年外，研究还从其父母或父母替代者处收集信息，以获取关于青少年心理健康及其相关因素的补充视角。父母提供的信息聚焦于五种青少年障碍——此前方法学研究一致表明，父母报告对这些障碍的诊断至关重要：注意缺陷多动障碍（attention-deficit/hyperactivity disorder）、品行障碍（conduct disorder）、对立违抗障碍（oppositional defiant disorder）、重性抑郁发作（major depressive episode）及恶劣心境障碍（dysthymic disorder）。NCS-A收集的人口统计学信息包括年龄、公民身份、出生地、犯罪史、族裔、祖父母出生地、家庭使用语言、父母出生地、种族、宗教信仰及性别。数据收集包含六个数据文件：（1）青少年家庭及学校受访者数据；（2）完成长版自填问卷的父母数据；（3）同时完成长版自填问卷与简短电话访谈的父母数据；（4）从青少年及父母数据中提取的诊断变量；（5）针对NCS-A青少年样本标准化后的K-BIT得分；（6）K-BIT原始数据。
