Abstract

OBJECTIVE: The relationship between eating disorders (EDs) and substance use (SU) has only been briefly described in literature using mainly adult populations. This study examined the prevalence and characteristics of SU among patients of an adolescent ED outpatient treatment program.

METHOD: A retrospective chart analysis was conducted to determine and subsequently compare medical status, psychosocial factors, treatment course and outcome between patients with and without SU.

RESULTS: Over 60% of patients with SU status (n?=?203) reported regularly consuming substances. 33.4% of substance users received a diagnosis involving purging behaviors compared to 5.9% of nonusers. Females composed 96.4% and 81.7% of users and nonusers, respectively. Users reported significantly more self-harm (57.7% of users vs. 38.6% of nonusers) but did not differ significantly in terms of trauma (abuse or victimization; 48.3% of users vs. 44.9% of nonusers). The percentage of ideal body weight significantly improved throughout treatment and did not differ by SU with a mean increase of 5.29% (SD?=?13.6) among nonusers compared to 5.45% (SD?=?7.5) of users. While users and nonusers did not differ before and after treatment in ED severity, users were more likely than nonusers to drop-out of treatment (41.5% of users vs. 25.2% of nonusers).

DISCUSSION: Adolescents with SU benefit from ED outpatient treatment as much as those without SU, however, users are more likely to drop-out. Therefore, treatment should target these adolescents' emotional dysregulation to improve treatment compliance. Further research is necessary to determine the efficacy of such an approach.
