Adherence
A short dietary screener (Multifactor Screener) using frequency questions and regression-based scoring algorithms can estimate usual intake of fruits, vegetables, percentage energy from fat, and fiber with correlations (0.5–0.8) comparable to full Food Frequency Questionnaires (FFQs), while exhibiting lower attenuation of relative risk estimates.
For large-scale health surveys or epidemiological studies, using a validated short dietary screener (like the Multifactor Screener) is a viable and efficient alternative to lengthy Food Frequency Questionnaires. It provides comparable accuracy in estimating fruit, vegetable, fat, and fiber intake while reducing respondent burden and minimizing the attenuation of observed health risks.
In the various validation studies, the correlations between screener estimates and estimated true intake were 0.5 –0.8. the performances of the screener and the full FFQ were similar; estimates of attenuation were lower for screeners than for full FFQs.
Why this rating
Validated across three distinct large-scale studies (OPEN, EATS, NIH-AARP) with multiple 24-hour recalls as the reference standard.
