This study used the National Longitudinal Survey of Youth and is the first to examine a 2-year report stability of substance use among adolescents while stratifying for gender, ethnicity, and age. This study examined lifetime use and age at onset report stability, and the internal consistency of reports while excluding nonusers and incident cases (respondents who may have initiated substance use between the two reporting periods) from the analyses. Report agreement of lifetime use for each substance was over 80% and was highest among alcohol users and lowest for cigarette and marijuana users. Report agreement was higher for female compared to male cigarette users. External consistency of lifetime use of cigarettes and marijuana was higher for whites compared to Hispanic or African American adolescents. Internal consistency was high but lifetime use reports were more stable than age at onset reports.
本研究使用了全国青少年纵向调查，是首次在按性别、种族和年龄分层的情况下，考察青少年物质使用情况两年报告的稳定性。本研究考察了终生使用情况、开始使用年龄报告的稳定性以及报告的内部一致性，同时在分析中排除了非使用者和新发病例（即在两个报告期之间可能开始使用物质的受访者）。每种物质终生使用情况的报告一致性超过80%，在酒精使用者中最高，在香烟和大麻使用者中最低。女性香烟使用者的报告一致性高于男性。与西班牙裔或非裔美国青少年相比，白人香烟和大麻终生使用情况的外部一致性更高。内部一致性较高，但终生使用报告比开始使用年龄报告更稳定。
