Evaluating content validity and test-retest reliability of the children's health risk behavior scale.

OBJECTIVE: Describe the instrument development process and report the validity and reliability of the Children's Health Risk Behavior Scale (CHRBS), a scale designed to screen for health risk behaviors among youth aged 10-13 Years. METHODS: Domain identification and item generation using the Youth Risk Behavior Surveillance Survey from the Centers for Disease Control and Prevention and testing relevance and test-retest reliability among a target audience sample of 77 fifth graders in their classrooms in two separate public school districts. RESULTS: Youth performed their tasks as expert item reviewers effectively. Twenty-one items comprise the CHRBS with a reading level determined to be at the third grade. CONCLUSIONS: We have developed a reliable and valid measure to assess late elementary youth's participation in health risk behavior.

Enhancing survey data collection among youth and adults: use of handheld and laptop computers.

Tobacco use, alcohol and other drug use, early sexual behavior, dietary practices, physical inactivity, and activities that contribute to unintentional and intentional injuries are a significant threat to the health of young people. These behaviors have immediate and long-term consequences and contribute to diminished health, educational, and social outcomes. Research suggests that health risk behaviors exhibited during adolescence and adulthood have their origins earlier in childhood and preventive interventions are less successful after the risk behaviors have begun. Therefore, efforts to prevent health risk behaviors are best initiated in late childhood or early adolescence. However, to document the efficacy of these efforts, reliable, valid, and parent/child-friendly systems of data collection are required. Computerized data collection for research has been found to improve privacy, confidentiality, and portability over the paper-and-pencil method, which, in turn, enhances the reliability of sensitive data such as alcohol use or sexual activity. We developed programming tools for the personal computer and a handheld personal data assistant to offer a comprehensive set of user interface design elements, relational databases, and ample programming languages so that adults could answer 261 items and youth 346 items. The purpose of the article was to describe an innovative handheld computer-assisted survey interview method of collecting sensitive data with children aged 9 to 11. The method was developed as part of a large multisite, national study to prevent substance use.
