Abstract

Introduction: Self-injurious behavior (SIB) is common among adolescents, and has been shown to be associated with eating disorders (ED). This study examines the prevalence of SIB and SIB screening in adolescents with ED, and associations with binge eating, purging, and diagnosis. Methods: Charts of 1,432 adolescents diagnosed with ED, aged 10-21 years, at an academic center between January 1997 and April 2008, were reviewed. Results: Of patients screened, 40.8% were reported to be engaging in SIB. Patients with a record of SIB were more likely to be female, have bulimia nervosa, or have a history of binge eating, purging, co-morbid mood disorder, substance use, or abuse. Patients who engaged in both binge eating and purging were more likely to report SIB than those engaged in restrictive behavior or either behavior alone. Providers documented screening for SIB in fewer than half of the patients. They were more likely to screen patients who fit a profile of a self-injurer: older patients who binge, purge, or had a history of substance use. Conclusions: SIB was common in this population, and supports extant literature on associations with bulimia nervosa, mood disorders, binge eating, purging, abuse, and substance use. Providers may selectively screen patients.
