Exploring the relationship between eating disorder symptoms and substance use severity in women with comorbid PTSD and substance use disorders

Abstract

Background: Eating disorders (ED) and substance use disorders (SUD) commonly co-occur, especially in conjunction with posttraumatic stress disorder (PTSD), yet little is known about ED and ED symptoms in women presenting to addiction treatment programs. Objective: We examined the association between ED symptoms and substance use frequency and severity in a sample of women with a DSM IV diagnosis of current SUD and PTSD enrolled in SUD treatment. Method: Participants were 122 women from four substance abuse treatment sites who participated in a multi-site clinical trial through the National Institute of Drug Abuse Clinical Trials Network (NIDA CTN). The Eating Disorder Examination-Questionnaire (EDE-Q), the Clinician’s Administered PTSD Scale (CAPS) and the Addiction Severity Index (ASI) were administered at baseline and correlational analyses were performed. Variables that significantly correlated with EDE-Q total and subscale scores were entered into a linear regression analysis. Results: Scores on the EDE-Q Global scale, as well as the Eating Concern, Weight Concern and Shape Concern subscales of the EDE-Q were significantly associated with Caucasian race/ethnicity, past 30 day opiate use, higher ASI Psychiatric Subscale score and lower ASI Employment Subscale score. Conclusion: Although exploratory, these findings suggest that there may be a relationship between addiction severity, use of certain drugs of abuse and eating disorder symptoms, particularly those involving weight and shape concerns in women with comorbid PTSD and SUD.
