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. © 2006, The Authors.Mahidol UniversityMedicineNursingArticleSCOPUS10.1111/j.1525-1446.2006.00574.x
