BackgroundWe aimed to develop tools that could be reliably used to evaluate self-efficacy for consuming vegetables and low-sugar foods and beverages for African American and Latino children living in inner-city communities.
MethodsA total of 112 children, aged 8-11years, identified by a parent as being either African-American or Latino, were recruited and administered questionnaires. Internal consistency, a measure of reliability, was assessed by calculating the Cronbach's alpha of test scores.
ResultsCronbach's alpha exceeded the threshold of acceptability of 0.70 for the Authors' Vegetables Self-Efficacy Index, and all three Low-Sugar Self-Efficacy Indices, including the Reference Index, the Authors' Low-Sugar Food and Beverage Index, and the Low-Sugar Beverages Index.
ConclusionsWe present internally consistent tools that could be reliably used to evaluate self-efficacy for consuming vegetables and low-sugar foods and beverages in 8-11-year-old African-American and Latino children from low socio-economic communities.
