目的：评估1999年青少年危险行为调查问卷(YRBS)的重测信度。方法：对4619名白人、黑人、西班牙裔和其他种族/民族的高中生进行两次YRBS问卷调查，调查间隔约两周。该问卷评估了一系列危害健康的行为。这项研究使用了一种协议，该协议保持了匿名性，但允许匹配时间1和时间2的响应。结果：Kappa值在23.6%~90.5%之间，平均值为60.7%，中位数为60.0%。Kappas没有因受访者的性别、年级或种族/民族而有所不同。大约五分之一(22.2%)的条目在时间1与时间2有显著不同的患病率估计。10个条目(13.9%)的Kappas都低于61%，并且时间1和时间2的患病率估计有显著差异。结论：总体上，学生似乎随着时间的推移报告了可靠的健康危险行为，但有几个条目需要进一步检查，以确定是否应该在未来的YRBS版本中修订或删除这些条目。
Purpose: To assess the test-retest reliability of the 1999 Youth Risk Behavior Survey (YRBS) questionnaire.Methods: A sample of 4619 male and female high school students from white, black, Hispanic, and other racial/ethnic groups completed the YRBS questionnaire on two occasions approximately two weeks apart. The questionnaire assesses a broad range of health risk behaviors. This study used a protocol that maintained anonymity yet allowed matching of Time-1 and Time-2 responses. The authors computed a kappa statistic for the 72 items measuring health risk behaviors, and compared group prevalence estimates at the two testing occasions.Results: Kappas ranged from 23.6% to 90.5%, with a mean of 60.7% and a median of 60.0%. Kappas did not differ by gender, grade, or race/ethnicity of the respondent. About one in five items (22.2%) had significantly different prevalence estimates at Time 1 vs. Time 2. Ten items, or 13.9%, had both kappas below 61% and significantly different Time-1 and Time-2 prevalence estimates.Conclusions: Overall, students appeared to report health risk behaviors reliably over time, but several items need to be examined further to determine whether they should be revised or deleted in future versions of the YRBS.
