Abstract
Although evidence suggests that hoarding may be associated with symptoms of ADHD, no study has examined this relationship in children.
Participants included 99 youth diagnosed with ADHD (and a parent) seen in a general outpatient psychiatry clinic. Children completed the Obsessive-Compulsive Inventory-Child Version, the Revised Child Anxiety and Depression Scale, and the Rosenberg Self-Esteem Scale. Parents completed the Children's Saving Inventory and Vanderbilt ADHD Diagnostic Rating Scale-Parent Version.
Inattentive and hyperactive/impulsive symptoms were the only indicator that differentiated those with and without clinically significant hoarding. Symptoms of ADHD, but not nonhoarding obsessive-compulsive symptoms, significantly predicted hoarding. Inattention and hyperactivity/impulsivity were uniquely associated with individual hoarding features. Hoarding symptoms mediated the relationship between ADHD and oppositionality.
These findings contribute to the growing literature about the association between hoarding and ADHD.
