Abstract

Abstract: The aim of the present study was to develop the ASKFV-SE tool to measure self-efficacy (SE) towards requesting fruits and vegetables (FV) in the home and school environment with school-age children (grades 4–5) from urban, ethnically diverse, low-income households. Cognitive interviews reduced the tool from eleven items to seven. The 7-item questionnaire was tested with 444 children. The items loaded on two factors: home SE (four items) and school SE (two items) with one item was excluded (<0⋅40). The reduced 6-item, 2-factor structure was the best fit for the data ( χ 2 = 45⋅09; df = 9; CFI = 0⋅835; RMSEA = 0⋅147). Confirmatory factory analysis revealed that the 4-item home SE had high reliability ( α = 0⋅73) and marginally acceptable reliability for the 2-item school SE ( α = 0⋅53). The pre-COVID intra-class correlation coefficient (ICC) was 0⋅584 ( P < 0⋅001; fair; n = 57) compared to 0⋅736 during-COVID ( P < 0⋅001; good; n 50). The ASKFV-SE tool measures children's SE for asking for FVs with strong psychometric properties and low participant burden.
