Non-Immersive Virtual Environments for the Treatment of Hoarding Disorder

Participants were guided to close their eyes and imagine discarding their personal object. The experimenter provided standardized verbal instructions to help participants visualize moving the item from their own space into a trash bin.

Participants used a desktop computer to interact with a virtual household environment. Their personal object, photographed beforehand, was digitally embedded in the scene. Using keyboard and mouse, participants navigated to the virtual garage and dragged the object into a virtual trash bin. The experimenter remained present to provide support.
