abstract="OBJECTIVE: Self-criticism has been proposed as a transdiagnostic predictor of disordered eating and nonsuicidal self-injury (NSSI). First, this study explored cross-sectional associations of multiple disordered eating behaviors, NSSI, and self-criticism. Second, it tested longitudinal relations of self-criticism with disordered eating and NSSI, adjusting for baseline levels of both behaviors. <br><br>METHODS: In Sub-study 1, undergraduates (N = 251, 79.5% female, M<sub>age</sub> = 19.1 years) completed self-report measures of disordered eating, NSSI, and self-criticism at baseline and after 8 weeks. In Sub-study 2, community-based young adults with histories of disordered eating, NSSI, or both (N = 517, 88.8% female, M<sub>age</sub> = 24.7 years) completed measures of disordered eating, NSSI, and self-criticism at baseline and after 4 weeks. All measures were completed online. <br><br>RESULTS: In Sub-study 1, both disordered eating and NSSI showed significant cross-sectional associations with self-criticism, and self-criticism was significantly related to binge eating, fasting, and NSSI at follow-up. In Sub-study 2, both behaviors again showed significant cross-sectional associations with self-criticism. Self-criticism showed significant longitudinal relations with fasting, purging, and excessive exercise. Longitudinal relations of self-criticism with NSSI varied across disordered eating behaviors. <br><br>DISCUSSION: NSSI showed cross-sectional associations with a range of disordered eating behaviors. Self-criticism reflects a common correlate of both disordered eating and NSSI. Evidence supported transdiagnostic longitudinal impact of self-criticism across multiple forms of disordered eating but provided more limited support for impacts on NSSI.<br><br>© 2020 Wiley Periodicals, Inc.<p /> <p>Language: en</p>",
