Symposium 52 - An Update on Research Investigating the Phenomenology of Hoarding Disorder: Features and Associated Factors

Friday, November 17
3:30 PM - 5:00 PM
Location: Aqua 310, Level 3, Aqua Level

Keywords: Hoarding | Risk / Vulnerability Factors | Comorbidity
Presentation Type: Symposium

Compulsive hoarding is defined as the accumulation of and failure to discard a large number of items that are of little use or value. It is associated with significant distress and/or impairment in functioning, and potentially may even pose a threat to the safety and health of an individual and their families. Traditionally conceptualized as a symptom dimension of Obsessive Compulsive Disorder, hoarding is now recognized as a psychiatric disorder and has received growing empirical and clinical interest in recent years. Current reports indicate that approximately 3-5% of the population may meet criteria for hoarding, and there is a mounting consensus that this phenomenon represents a considerable public health burden.  Despite these advances, many questions regarding the phenomenology of hoarding persist. In particular, issues related to risk and vulnerability, accurate assessment, comorbidity, and treatment remain unanswered, directly hampering future efforts to develop more effective treatments. This symposium will highlight research on hoarding across diverse populations and across multiple settings--including youth, sub-clinical populations, older adults, and those seeking treatments versus those who may not. A multidisciplinary group of presenters will summarize and discuss recent advances in our understanding of hoarding, which can be directly translated into potential avenues for future etiological and treatment investigations, and similarly help propel research on dissemination efforts. 

Kiara Timpano will present data characterizing the full dimension of hoarding, focusing on factors that increase risk and vulnerability across the spectrum of saving behaviors. Next, Jordana Muroff will report on technological advances in assessment techniques, by describing an utomatic, computer-based rating of room clutter. Michelle Rozenman will present data better characterizing hoarding symptoms in a youth sample of individuals with OCD, while Eric Storch will describe hoarding features and symptoms in a sample of youth with Autism spectrum disorders. Finally, Greg Chasson will examine stigma associated with hoarding in a general population sample, along with how self-stigma may influence treatment ambivalence and willingness to pursue therapy. Dave Tolin will serve as discussant for the symposium. In addition to considering common themes among the presentations, he will discuss the interplay between basic science and treatment. Emphasis will be given to the importance of disseminating knowledge about hoarding, as well as future avenues of research.
