title: Reliability of a Kid's Activity and Nutrition Questionnaire for School-Based SNAP-Ed Interventions as Part of a Tiered Development Process.
abstract: To assess the reliability of the Kids' Activity and Nutrition Questionnaire (KAN-Q) as part of a tiered process for developing Supplemental Nutrition Assistance Program-Education tools.
  
  
  
  The KAN-Q was administered at 2 time points to assess internal consistency using standardized values of Cronbach α and test-retest reliability using the intraclass correlation coefficient for continuous variables, Cohen's kappa (κ) statistic for categorical variables, and the weighted κ statistic for ordinal data.
  
  
  
  Data were collected from 119 fourth graders. Cronbach α was adequate for behavior (.71) and knowledge (.72) scales and nutrition behavior (.78) and nutrition knowledge (.75) subscales. Test-retest reliability was generally acceptable, with intraclass correlation coefficients from 0.40 to 0.75 and κ coefficients showing fair to substantial agreement (0.30 to 0.72).
  
  
  
  The KAN-Q is a practical and reliable questionnaire for school-based administration that aligns directly with Supplemental Nutrition Assistance Program-Education evaluation priorities.
