Question

BlackTom AI · Accepted Answer

In this question, we’re given a scenario where Simon fills out a set of written questions about the amount and quantity of foods he usually eats, and we must identify the measurement method involved.
Option a: '24 hour dietary recall' refers to a method where a respondent reports all foods and beverages consumed in the previous 24 hours. This is typically an interview-based approach, not a written questionnaire about usual intake, so this option does not match the described method.
Option b: 'Diet survey' is a broad term that could describe various methods, but it is not a standard, specific name for a common dietary assessment tool used to capture usual intake via a written format. It lacks the precise alignment with the scenario as written.
Option c: 'Food frequency questionnaire' (FFQ) is a common instrument in nutrition research and practice used to assess habitual or usual intake by asking respondents how often they consume a list of foods over a specified period. Since the stem describes written questions about the amount and quantity of foods usually eaten, FFQ fits this description well as a written dietary intake measure.
Option d: 'Diet history' is another technique used to assess usual intake, but it typically involves a comprehensive interview to detail long-term eating patterns, not simply a series of written questions. Given the emphasis on written questions, this option is less consistent with the description than the FFQ.

Overall, the scenario matches a method designed to capture habitual intake via a structured written questionnaire, which is characteristic of a Food Frequency Questionnaire, whereas the other options refer to more interview-based or broader, less specific methods. The distinctions hinge on form (written vs. interview) and focus (usual intake over time vs. a single recent day), which makes FFQ the best fit for the described approach.
