Abstrakt: Objectives: Nutrition backlash is a disposition defined by negative feelings about dietary recommendations. Past research has measured nutrition backlash using the nutrition backlash scale (NBS) and found that it is negatively related to the consumption of fruits and vegetables. The aim of this study was to examine several aspects of the NBS, including factor structure, discriminant validity, and relationship to demographic characteristics and health behaviors.
Methods: Adults were recruited to participate in two studies. Study 1 (N = 480) included measures of nutritional backlash, information overload, worry, fatalism, and nutrition-related behaviors. Study 2 (N = 399) was a follow-up that examined the factor structure of the NBS in a separate sample.
Results: In study 1, a six-item version of the NBS was found to be a good fit for the data and discriminant from overload, worry, and fatalism. NBS was higher for those with less education, non-white participants, and men. Individuals with higher backlash were less likely to look at nutritional labels and to use sunscreen. Study 2 confirmed the factor structure from study 1.
Conclusions: A six-item version of the NBS was found to be reliable, discriminant from related measures, higher in underserved groups (less-educated, non-white, and male participants), and related to nutrition label use.
