Relationship Between Schizotypal Traits, Hoarding

J Affect Disord; ePub 2018 May 4; Weintraub, et al

Individuals who fell within the clinical range of hoarding symptoms endorsed significantly greater levels of schizotypal symptoms compared to those with normative saving behaviors, according to a recent study. This underscores the importance of assessing schizotypal traits in patients with hoarding. Researchers examined the association between hoarding and schizotypal symptoms using multivariate analyses in 2 samples—a sample of 120 young adults and a community sample of 291 individuals. They found:

  • Individuals who fell within the clinical range on the Saving Inventory Revised endorsed significantly greater levels of schizotypal symptoms compared to those with normative saving behaviors.
  • Odd speech, magical thinking, and social anxiety were the most consistent schizotypal correlates of hoarding symptoms.
  • Perceived cognitive dysfunction mediated the effects between odd speech and social anxiety and hoarding symptoms, suggesting that shared abnormalities in cognitive functioning may help explain the relationship between hoarding and schizotypy.
