【 摘 要 】

OBJECTIVE: To present a Diet Quality Index proper for dietary intake studies of Brazilian adults. METHODS: A diet quality index to analyze the incorporation of healthy food choices was associated with a digital food guide. This index includes moderation components, destined to indicate foods that may represent a risk when in excess, and adequacy components that include sources of nutrients and bioactive compounds in order to help individuals meet their nutritional requirements. The diet quality index-digital food guide performance was measured by determining its psychometric properties, namely content and construct validity, as well as internal consistency. RESULTS: The moderation and adequacy components correlated weakly with dietary energy (-0.16 to 0.09). The strongest correlation (0.52) occurred between the component 'sugars and sweets' and the total score. The Cronbach's coefficient alpha for reliability was 0.36. CONCLUSION: Given that diet quality is a complex and multidimensional construct, the Diet Quality Index-Digital Food Guide, whose validity is comparable to those of other indices, is a useful resource for Brazilian dietary studies. However, new studies can provide additional information to improve its reliability.
