ABSTRACT
Background: Diet quality assessment in community health settings is critical to reduce the incidence and improve management of diet-related chronic disease. Unfortunately, understandable and actionable brief dietary screening tools that empower individuals are nearly absent.
Purpose: The purpose of this article is to describe two rigorous methodological approaches to validate and assess suitability of the Rapid Diet Quality Screener (RDQS).
Methods: The first phase consisted of the content validation of a food consumption frequency questionnaire based on the Alternative Healthy Eating Index (AHEI). The second phase involved evaluating the design of the RDQS using the Suitability Assessment of Materials (SAM).
Results: The RDQS and its food/beverage consumption frequency questions met established validity criteria consistent with the AHEI dietary metric components. The SAM evaluation was superior, thus elevating the RDQS from a one-way process of users assessing their diet quality to a two-way process allowing users to engage in behavior change that positively supports health and well-being.
Translation to Health Education Practice: The RDQS enables health educators to quickly screen an individual’s diet quality to determine risk, guide brief counseling, and monitor progress with the populations they engage.
