Content Validity and Reliability of a Food Frequency Questionnaire with Intense Sweeteners (FFQIS) in a Hispanic Population

Abstract

Background: Artificial sweeteners are substances with high potential sweetness and low caloric value, some reasons why they are widely used by food manufacturers. Currently, although consumption of non-caloric sweeteners in processed food has increased, no validated instrument in the Spanish language is available to assess the amounts eaten of foods containing these additives, making imperative to have a reliable instrument to quantify the food consumed for investigational purposes. The aim of this study was to assess the content validity and reliability of a food frequency questionnaire for sweeteners (FFQIS) to calculate consumption among a Hispanic population.
