Objective: To assess and compare clinical symptoms and psychometric analysis of adult patients with avoidant/restrictive food intake disorder (ARFID) with those with anorexia nervosa (AN).
Method: We completed a retrospective review of adult patients with a feeding and eating disorder assessed between 1990 and 2005 that qualified for a diagnosis of ARFID. Patients with ARFID were compared with those with AN, with respect to the demographics, clinical symptoms and psychometric analysis.
Results: Using the criteria of the fifth edition of the Diagnostic and Statistical Manual, 95 (9.2%) of 1029 patients with a feeding and eating disorder met the criteria for ARFID. All patients with ARFID were women. The ARFID group had a significantly shorter duration of illness, lower rates of hospital admission history and less severe psychopathology than the AN group.
Conclusions: Adult patients with ARFID in this study were clinically distinct from those with AN and somewhat different from paediatric patients with ARFID in previous studies. Copyright © 2016 John Wiley & Sons, Ltd and Eating Disorders Association.
