Development and validation of a tool to assess knowledge of healthy lifestyles in early grade school children

Abstract

Abstract Objective Healthy habits during childhood has been of prime importance. We aimed to gather baseline information about health habits from children in kindergarten and first grade (typically ages 5–7). Our objectives were to validate the questionnaire in assessing health habits, as well as the electronic audience response system, iClicker (MPS, Gordonsville, VA), in this age group. Results The questionnaire completed by 75 kindergarteners and 66 first graders. For the first graders, questions involving healthy choices were answered correctly 78% of the time (range 8–94%) and had 84% agreement on repeat testing (range 64–93%). Questions on diabetes were answered correctly 79% of the time (range 65–94%) and had 85% agreement on repeat testing. Crohnbach’s alpha was calculated to determine the reliability of the questionnaire: on the revised kindergarten questionnaire, this ranged from 0.79 to 0.81 on Day 1 and 0.84–0.97 on Day 5; for the first graders, this ranged 0.79–0.81 on Day 1 and 0.84–0.97 on Day 5. Both kindergarteners and first graders answered the simplest of the basic knowledge questions correctly > 80% of the time, with acceptable test–retest agreement. Additionally, these children demonstrated acceptable understanding of the use of the iClicker classroom response system.
