The Canadian Food Intake Screener for assessing alignment of adults ’ dietary intake with the 2019 Canada’s Food Guide healthy food choices recommendations: scoring system and construct validity
Applied Physiology, Nutrition, and Metabolism, Ahead of Print. The Canadian Food Intake Screener/Questionnaire court canadien sur les apports alimentaires was developed to rapidly assess alignment of adults ’ dietary intake over the past month with the 2019 Canada’s Food Guide’s healthy food choices recommendations. From July to December 2021, adults (n = 154) aged 18–65 years completed the screener and up to two 24 h dietary recalls. The screener scoring system was aligned with the Healt hy Eating Food Index-2019 (HEFI-2019), to the extent possible. Analysis of variance compared screener scores among subgroups with known differences in diet quality. Using the recall data, the National Cancer Institute multivariate method was used to model HEFI-2019 components, with the screener scor e as a covariate, and the correlation coefficient between screener and total HEFI-2019 scores was estimated. The mean screener score was 35 points (SD = 4.7; maximum 65), ranging from 26 (1st percentile) to 45 (99th percentile). Differences in scores in hypothesized directions were evident by ge nder identity (p = 0.06), perceived income adequacy (p = 0.07), education (p = 0.02), and smoking status (p = 0.003). The correlation between screener and HEFI-2019 scores was 0.53 (SE = 0.12). The screener’s moderate construct validity supports its use for rapid assessment of alignment of adults’ intake with the healthy food choices recommendations when comprehen...
