The present set of studies developed and tested the Food Disgust Picture Scale (FDPS). This is a tool for the assessment of food disgust sensitivity that will measure disgust and predict possible reactions. This eight-picture tool can be used in complement to or as a replacement for currently available text-based measures. In an exploratory Study 1 (N = 57), we constructed a scale consisting of eight pictures. Most of them were taken from validated picture databases. They proved powerful in the assessment of food disgust sensitivity. Study 2 built on these results and refined the scale by substituting pictures from Study 1 with freely available images displaying similar content. The basic structure of the FDPS was then replicated in a bigger sample of Swiss adults (N = 538). Correlational analyses using the eight-item Food Disgust Scale (FDS short), the revised version of the Disgust Scale (DS-R), and the food neophobia scale (FNS) supported the convergent validity of the FDPS. In Study 3 (N = 226), we used a test-retest design to demonstrate the short-term stability of the FDPS. As a result of these studies, the present work provides a short and comprehensive measure of food disgust sensitivity. This novel approach of using pictures to induce a disgust response independently of language significantly facilitates intercultural research on disgust. The FDPS will further contribute to the understanding of food-related disgust and its impact on our food choices.
