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.
