creator Schwartz, Natalie advisor Haedt-Matt, Alissa The trait of perfectionism is a psychological factor linked with the development of disordered eating, though the relation is unclear with some studies pointing to perfectionism as a predictor of eating disorder symptoms, while other studies have failed to find a statistically significant association. These discrepant findings suggest a need for understanding other factors that could be impacting the association. Research has suggested that individuals with eating disorders perform better than controls on knowledge of sources of nutrients and that while individuals with eating disorders spend more time reading about nutrition, this knowledge tends to be selective and skewed towards the aspects that maintain the eating disorder. The current study aimed to investigate the role of nutrition knowledge as a factor that may significantly influence the association between perfectionism and disordered eating attitudes. College women (N=122) completed several questionnaires related to disordered eating, nutrition knowledge, and perfectionism. The main research questions were: 1) whether perfectionism was related to disordered eating attitudes, 2) whether nutrition knowledge was related to disordered eating attitudes, and 3) whether nutrition knowledge moderated the relation between perfectionism and disordered eating attitudes. Results supported a positive association between perfectionism and disordered eating attitudes, in line with previous research. Despite a non-significant association between nutrition knowledge and disordered eating attitudes, there was found to be trend level significance (p<.07) for one moderation model. Specifically, the model assessing overall body dissatisfaction accounted for 33.34% of the variance, with a significant main effect for the level of perfectionism,suggesting the greater the degree of perfectionism traits, the greater the level of body dissatisfaction. While more research is needed to further develop an understanding of the link between perfectionism and disordered eating, nutrition knowledge is one possible avenue to explore in order to develop more effective prevention and intervention efforts.
