Comorbidity in Hoarding Disorder

Abstract

Background: Hoarding Disorder (HD) is currently under consideration for inclusion as a distinct disorder in DSM-5 (1). Few studies have examined comorbidity patterns in people who hoard, and the ones that have suffer from serious methodological shortcomings including drawing from populations already diagnosed with obsessive compulsive disorder (OCD), using outdated definitions of hoarding, and relying on inadequate assessments of hoarding. The present study is the first large-scale study of comorbidity in a sample of people meeting recently proposed criteria for hoarding disorder (1) and relying on validated assessment procedures.
