Thanks for all of your insight! Some of the questions in this study might seem harder to relate to than others. We're doing our best to cover all sorts of different experiences, as there are few studies in this area as of yet.
There are differences in the definitions of collecting and hoarding and so we recognise them as two very different behaviours, which share the similarity of acquiring material items. Once we have enough responses, we'll start looking at what the key psychological differences are, and hopefully this can lead to better therapies for hoarding difficulties while ensuring that collectors aren't diagnosed by mistake.
