OBJECTIVES
This study examined, across three racial/ethnic groups, how the inclusion of data on drug use of dropouts can alter estimates of adolescent drug use rates.
METHODS
Self-report rates of lifetime prevalence and use in the previous 30 days were obtained from Mexican American, White non-Hispanic, and Native American student (n = 738) and dropouts (n = 774). Rates for the age cohort (students and dropouts) were estimated with a weighted correction formula.
RESULTS
Rates of use reported by dropouts were 1.2 to 6.4 times higher than those reported by students. Corrected rates resulted in changes in relative rates of use by different ethnic groups.
CONCLUSIONS
When only in-school data are available, errors in estimating drug use among groups with high rates of school dropout can be substantial. Correction of student-based data to include drug use of dropouts leads to important changes in estimated levels of drug use and alters estimates of the relative rates of use for racial/ethnic minority groups with high dropout rates.
目的
本研究在三个种族/族裔群体中考察了纳入辍学者药物使用数据如何改变青少年药物使用率的估计。
方法
从墨西哥裔美国人、非西班牙裔白人及美国原住民学生（n = 738）和辍学者（n = 774）中获取终身患病率及过去30天内使用情况的自我报告率。使用加权校正公式估计该年龄队列（学生和辍学者）的比率。
结果
辍学者报告的使用率比学生报告的高1.2至6.4倍。校正后的比率导致不同种族群体使用相对比率的变化。
结论
当仅可获得校内数据时，估计高辍学率群体药物使用情况时的误差可能很大。校正基于学生的数据以纳入辍学者的药物使用情况会导致药物使用估计水平的重要变化，并改变对高辍学率种族/族裔少数群体使用相对比率的估计。
