The Food Disgust Picture Scale (FDPS) is a newly developed picture tool that can be used to conduct cross-cultural assessments of food disgust sensitivity. It consists of eight food-related pictures, which participants rate according to the level of disgust they evoke. Due to the undeniable influence of culture on what individuals consider as disgusting, the FDPS’s validity across different food cultures is an interesting topic for research. The aim of the present study was to conduct a cross-national comparison of the FDPS in Switzerland and China. In total, 576 participants were recruited in China and 538 were recruited in Switzerland. The usability and construct validity of the FDPS were compared between the two countries using confirmatory factor analyses. In the current study we present two main findings. First, dropping one of the meat-related items and thereby reducing the eight-item FDPS to seven items improved the model fit in the Chinese (CFI = 0.98) and Swiss (CFI = 0.98) samples. Furthermore, it showed that the scale is a valid tool for the assessment of food disgust sensitivity in China. Second, using nested model comparisons, the present study has provided support for the model’s invariance across the two countries.
