Perceived Diet Quality Validation Study
The objective of this research was to develop and validate a novel tool for measuring perceived diet quality. Development included literature searches, focus groups, and thematic analysis. Validation included expert reviews, cognitive interviews, and a cross-sectional, nonexperimental, online survey. The dataset contains the result of the cross-sectional, nonexperimental, online survey that conducted from April to September 2025. The final sample size for the online survey was 605 participants in Arkansas, Louisiana, and Mississippi. The new tool included 11 items -- 3 addressing perceived diet quality based on qualitative, graded, and numeric ratings; satisfaction with diet healthfulness; balanced meals; meal planning/preparation; nutrition knowledge; home cooking vs eating out/takeout; food label use; difficulty eating healthy; and guilt/regret about food choices. Seven of the 11 items were retained for the final solution -- 3 items addressing perceived diet quality, satisfaction with diet healthfulness, balanced meals, meal planning/preparation and home cooking vs eating out/takeout. The Perceived Diet Quality Scale was created by summing the scores of the 7 items. Content, face, criterion, and convergent validity and internal reliability were established for the scale. Assessment accuracy of the 3 diet quality items was determined by comparisons with Healthy Eating Index and Global Dietary Recommendations scores.The Data Dictionary file describes column names/variables, their data types, and length, and the Abbreviations data dictionary provides meanings for abbreviations used in the dataset.
