- Description
- Assessing individual food choices within health and nutrition related research is challenging and there is a strong need for valid and reliable instruments. In this paper, we introduce the Multiple Food Test as a new tool for measuring food choices and applied nutrition knowledge. The Multiple Food Test has the format of an image selection task. Part one of the Multiple Food Test consists of 18 trials in which participants are presented with sets of four food items and asked to choose one item they would prefer to consume (choice scale). In part two, participants saw the same 18 trials and were asked to indicate which of the items presented they perceived as being the healthiest (applied knowledge scale). Results across three studies (total N = 666) indicate that both subscales of the Multiple Food Test have good psychometric properties. Healthier choices were significantly associated with implicit theories of health, healthy eating frequency and importance (Study 1), a stronger health versus taste motive (Study 1 and 2), self-control, and habitual fruit and vegetable intake (Study 2). In Study 3, choices in the Multiple Food Test positively predicted actual food choices. The applied knowledge scale showed agreement with an existing nutrition knowledge scale, and higher scores were associated with higher levels of self-control (Study 2). The Multiple Food Test presents new opportunities to evaluate underlying variables and interventions that influence food choice or eating behavior.
