The extent to which body image-related thoughts are endorsed and drive behaviors, a process known as Body Image-Related Cognitive Fusion (BI-CF), is an important contributor to disordered eating. Moreover, negative mood and negative self-referential processes (e.g., low self-compassion) have been reportedly associated with disordered eating; however, their associations with BI-CF are not known. The aim of this study was to investigate, among young adults, the association between (1) BI-CF and disordered eating attitudes and behaviors (2) BI-CF and self-compassion, and (3) whether sad mood influences BI-CF.
