Relationship between Autistic Traits and Hoarding in a Large Non-Clinical Chinese Sample: Mediating Effect of Anxiety and Depression

Abstract

Researchers and clinical practitioners have found that hoarding appears in many autism patients and that most of these patients show high anxiety and depression. There is no consensus on the relationship between autistic traits and hoarding, and little research concerning the role of negative emotions. This study investigated the relationship between autistic traits and hoarding in a large non-clinical Chinese sample. Participants were 3,229 university students (M age = 20.5 yr., SD = 1.6; 1,839 men) who were recruited in classroom. They completed measures of hoarding, autistic symptomology, anxiety, and depression: specifically the Saving Inventory–Revised, the Autism-Spectrum Quotient, the Zung Self-Rating Anxiety Scale, and The Center for Epidemiological Studies Depression Scale. Mediating effects of anxiety and depression in the correlation between autistic traits and hoarding were also explored. There was a weak but significant correlation between autistic traits and hoarding. Significant mediating effects of anxiety and depression were observed. Hoarding in people with high autistic traits could be influenced by anxiety and depression.
