abstract="OBJECTIVE: To examine the validity and reliability of a questionnaire administered with an audience response system (ARS). <br><br>DESIGN: Cross-sectional study. SETTING: Two New York City public elementary schools. PARTICIPANTS: Fourth- and fifth-grade students. MAIN OUTCOME MEASURES: A Food, Health, and Choices questionnaire (FHC-Q) assessed energy balance-related behaviors (EBRBs) including intake of fruits and vegetables, sugar-sweetened beverages, processed packaged snacks, and fast food; physical activity; recreational screen time; and associated psychosocial determinants (≥ 3 questions/outcome scale). Previously validated reference instruments were used for relative validation. The ARS format was compared with a paper-and-pencil format. All measures were administered in a classroom setting. ANALYSIS: Pearson correlation coefficients between the reference instruments and the FHC-Q were calculated. Internal consistency reliabilities were evaluated with Cronbach α. Spearman rank correlation, intra-class correlation, and percent agreement were used for test-retest reliability between paper-and-pencil and ARS, and between 2 ARS FHC-Q administrations. <br><br>RESULTS: Correlations for EBRBs with reference instruments ranged from 0.38 to 0.61 (P < .01). Cronbach α ranged from.77 to.92 for EBRBs and.74 to.90 for psychosocial determinants. Test-retest reliability correlations ranged from 0.36 to 0.87 (P < .001). Agreement for knowledge questions ranged from 69.8% to 84.8%. <br><br>CONCLUSIONS AND IMPLICATIONS: The ARS FHC-Q has acceptable validity and reliability for collecting data on EBRBs and associated psychosocial determinants for upper-elementary students.<br><br>Copyright © 2016 Society for Nutrition Education and Behavior.
