National Survey of American Life - Adolescent Supplement (NSAL-A), 2001-2004

The National Survey of American Life Adolescent Supplement (NSAL-A), 2001-2004, was designed to estimate the lifetime-to-date and current prevalence, age-of-onset distributions, course, and comorbidity of DSM-IV disorders among African American and Caribbean 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. In addition and similar to the NSAL adult dataset (Collaborative Psychiatric Epidemiology Surveys (CPES), 2001-2003 [United States] (ICPSR 20240)), the adolescent dataset contains detailed measures of health; social conditions; stressors; distress; racial identity; subjective, neighborhood conditions; activities and school; media; and social and psychological protective and risk factors. Numerous variables from the adult dataset have been merged into the adolescent dataset, as the NSAL adult and adolescent respondents reside in the same households. Some of these variables apply to the entire household (i.e. region, urbanicity, and family income), while others apply specifically to the NSAL adult respondent living in the adolescent's household (i.e. adult years of education, adult marital status, and adult nativity [foreign-born vs. US born]). The immigration measures were asked of Caribbean black adult respondents only. No comparable measures assess the immigration and generational status of the Caribbean black adolescent respondents. The adult dataset measures are merged into the adolescent dataset to assist in approximating these measures for adolescent respondents. The NSAL adolescent dataset also includes variables for other non-core and experimental disorders. These include tobacco use/nicotine dependence, premenstrual syndrome, minor depression, recurrent brief depression, hypomania, and hypomania sub-threshold. Demographic variables include age, race and ethnicity, ancestry or national origins, height, weight, marital status, income, and education level.

2001-2004年美国全国生活调查青少年补充调查（National Survey of American Life Adolescent Supplement, NSAL-A）旨在估算美国非裔与加勒比裔青少年的《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）》精神障碍的终身累积患病率与当前时点患病率、起病年龄分布、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；描述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。此外，与NSAL成人数据集（2001-2003年美国合作精神病流行病学调查（Collaborative Psychiatric Epidemiology Surveys, CPES）[ICPSR 20240]）类似，该青少年数据集包含健康状况、社会环境、应激源、心理困扰、种族认同、主观感知的社区环境、日常活动与学业、媒体接触，以及社会与心理层面的保护及风险因素等详细测量指标。由于NSAL的成人与青少年受访者同住一户，大量成人数据集变量已被整合纳入青少年数据集。其中部分变量适用于整个家庭（如所在地区、城市化水平与家庭收入），其余变量则专门针对青少年家庭中的成人受访者（如成人受教育年限、成人婚姻状况与成人出生地[foreign-born vs. US born]）。移民相关测量指标仅针对加勒比黑人成人受访者设置，目前尚无等效指标可用于评估加勒比黑人青少年受访者的移民情况与代际身份，因此将成人数据集指标整合纳入青少年数据集，以辅助估算青少年受访者的此类相关指标。NSAL青少年数据集还涵盖其他非核心与实验性精神障碍相关变量，包括烟草使用/尼古丁依赖、经前期综合征、轻度抑郁、复发性短暂抑郁、轻躁狂及阈下轻躁狂。人口统计学变量包括年龄、种族与族裔、祖先或民族起源、身高、体重、婚姻状况、收入与受教育水平。
