A measurement scale (i.e., a validated questionnaire) is used within the fields of psychology and nutrition to measure one’s subjective experience or attitude to a stimulus by indicating one’s level of agreement to a statement by selecting a position along a continuous line between two end-points. The VAS has been used in nutrition research to measure ingestive behavior, pre- and postprandial hunger, fullness, desire to eat, and prospective food consumption (PFC) (Douglass & Leidy, 2019).
