Hoarding Disorder

What is Hoarding Disorder?

Hoarding disorder (HD) is characterised by difficulty discarding possessions, resulting in excessive clutter that interferes with the individual’s capacity to use active living areas within their house as intended

What is this research about?

Associate Professor Jessica Grisham’s research on Hoarding Disorder includes a study delineating key differences between hoarding and Obsessive Compulsive Disorder (OCD), as well as the first laboratory study of neuropsychological impairment associated with hoarding. Jessica is currently interested in deficits in self-regulation in hoarding disorder, as well as how emotions affect decision-making among individuals with hoarding difficulties and the role of impaired distress tolerance. She is also interested in developing computerised and online interventions for HD.

Research students involved:

Peter Baldwin: Peter’s research focuses on hoarding disorder, specifically the psychological and physiological mechanisms of decision-making in hoarding disorder. By identifying and targeting these mechanisms Peter hopes to better understand how the disorder develops and how we can improve treatment outcomes.
