Self‐Criticism as a Transdiagnostic Process in Nonsuicidal Self‐Injury and Disordered Eating: Systematic Review and Meta‐Analysis
Year: 2018

Study designs: Systematic Review, Meta-Analysis
Abstract: Nonsuicidal self-injury (NSSI) and disordered eating (DE) are highly comorbid and may be regarded as belonging to a spectrum of self-harm behaviors. We investigated self-criticism as a transdiagnostic correlate of these behaviors, in keeping with etiological theories of both NSSI and DE. We reviewed the literature and meta-analyzed the relation of self-criticism to both NSSI (15 studies; 17 effect sizes) and DE (24 studies; 29 effect sizes). Results showed equivalent, moderate-to-large effects for the relation of self-criticism to NSSI (r = .38; CI: .29-.46) and DE (r = .40; CI: .34-.45). The relation of NSSI to self-criticism generalized across multiple potential moderators. DE behavior type moderated the relation of self-criticism to DE, with a stronger relation emerging for purging than restriction. Findings support self-criticism as a possible candidate for transdiagnostic pathways to self-harm.
