The ARU Possessions and Hoarding Collective

The ARU Possessions and Hoarding Collective is a group of academics and professionals who aim to improve understanding of how people interact with their possessions.

Many individuals report complex relationships with their possessions, including acquiring too many and trouble with organising them, leading to clutter and difficulties discarding them. At times, such behaviours can become excessive, resulting in problems in everyday life and even hoarding disorder, which is a mental health condition.

As part of our activities, we research hoarding and how can it affect individuals and their wider surroundings and family members. We are also interested in how service provision is currently delivered, and how it can be improved.

The ARU Possessions and Hoarding Collective (PoHoC) is part of the UK Hoarding Research Network.
