Toned muscularity continues to emerge as a salient aspect of women's body image. However, there is a dearth of research investigating the potentially maladaptive eating practices and related cognitions that accompany the drive for muscularity in women. This may be attributable to the limited empirical and clinical attention previously given to muscularity-oriented disordered eating and, accordingly, the lack of validated measures assessing these concerns. To address this knowledge gap, our study aimed to provide a preliminary evaluation of the factor structure and core psychometric properties of a recently developed measure of muscularity-oriented disordered eating, the Muscularity-Oriented Eating Test (MOET), in university women in Australia.
