The Youth Risk Behavior Survey (YRBS) is a key element in the surveillance system used by the Centers for Disease Control & Prevention (CDC) to monitor health risks among US high school students. Presented here are results of a methodological evaluation of the YRBS before & after it introduced a revised, multiracial question to assess respondent race & ethnicity in 1999. Data collected in 2000 from a convenience sample of youth in grades 9-12 from 61 schools in 20 states (final N = 4,619) indicate that allowing students to select more than 1 response to the race/ethnicity question had only a minimal effect on reported race/ethnicity; 96+% of students were categorized in the same way regardless of response options. However, the new race/ethnicity question is highly reliable & produces a lower rate of nonresponse. 2 Tables, 10 References. K. Hyatt Stewart

This study investigates whether the type of parental permission affects prevalence estimates for risk behaviors from the national 2001 Youth Risk Behavior Survey. Participants were 13,195 students from 143 schools, of which 65% used passive permission and 35% active permission. Student participation rates were 86.7% in passive permission schools and 77.3% in active permission schools. For 24 of 26 behaviors tested, no significant differences were seen in the prevalence of risk behavior by type of parental permission. As long as high response rates are obtained, type of parental permission does not affect prevalence estimates for risk behaviors that are based on self-report.

Purpose The Youth Risk Behavior Survey (YRBS) monitors behaviors, experiences, and conditions affecting the health of high school students nationwide. This study examined the test-retest reliability of the 2021 national YRBS questionnaire. Design Respondents completed a Time 1 and Time 2 paper-and-pencil questionnaire approximately 2 weeks apart during February to May 2022. Data were linked in such a way as to preserve anonymity. Setting Convenience sample of high schools. Subjects High school students (N = 588). Measures Health risk behaviors and experiences assessed on the 2021 national YRBS questionnaire. Analysis Time 1 and Time 2 responses were compared for each questionnaire item using the McNemar's test. Then, Cohen's kappa coefficients tested the agreement between Time 1 and Time 2 responses overall, and by sex, grade, and Black, White, and Hispanic race and ethnicity. Results Among the 74 items analyzed, 96% had at least moderate reliability, and 73% had substantial or almost perfect reliability. The mean Cohen's kappa was .68. McNemar's test findings showed Time 1 and Time 2 data significantly differed ( P < .01) for 9 items (12%). Conclusion Reliable health behavior measures are important in the development of youth-focused public health programs and policies. Findings suggest the national YRBS questionnaire is a reliable instrument. Such findings lend support to relying on adolescent self-reported data when monitoring health behaviors using the YRBS.

The authors examined whether paper-and-pencil and Web surveys administered in the school setting yield equivalent risk behavior prevalence estimates. Data were from a methods study conducted by the Centers for Disease Control and Prevention (CDC) in spring 2008. Intact classes of 9th- or 10th-grade students were assigned randomly to complete a survey via paper-and-pencil or Web. Data from 5,227 students were analyzed using logistic regression to identify associations of mode with reporting of 74 risk behaviors. Mode was associated with reporting of only 7 of the 74 risk behaviors. Results indicate prevalence estimates from paper-and-pencil and Web school-based surveys are generally equivalent.
