@bigkahunaburger I would be extremely interested in your source material on this part of your masters. Can you cite the authors please?
We massively lack actual H/D skilled therapists as well as the money and time needed to be invested in them, which means we send most people on 6 weeks of IAPT with general therapists at best, but still call the condition hard to treat. (not saying it isn't, just question how we measure these things)
There are often visible overlaps with OCD. For a long time one of the reasons H/D was so intractable to treat, was because it was considered a sub section of OCD, so OCD theories on treatment where used. They proved almost totally ineffective to treat H/D, which added to the idea it couldn't be treated.
(We finally get a separate classification in DSM 5 but it continued to focus on chaotic hoarding that might affect others.)
We have also for a very long time tried to call 'symptom reduction,' cure, and based how well a person was doing on what their home looked like, leading to the idea that a cleaned out home meant the person was 'cured' and when it filled back up, they had 'relapsed.'
I hesitate to use the term OCD about myself as I have no diagnosis, and it seems unfair to those who have fought to be diagnosed, but I was washing all incoming shopping, and wearing latex gloves outdoors, long before Covid, alongside huge cleaning rituals.
I put it down to a direct rebellion/result of having grown up in a squalor hoard.(as well as other dirty environments I'd had no control in)
I've actually overcome the worst of the OTT cleaning, slowly but surely on my own, as part of working on myself and how 'my' H/D manifests.
...the person commonly will be extremely tidy and have OCD in their tendencies towards order, cleanliness and hygiene. But then it starts to spill over because they simply cant maintain that. They simply cannot control their environment that much - things spill, things get lost, etc - and that is when the hoarding begins - as a form of OCD in that it is their way to maintain control. (my underlining)
Some concern that you have been taught to recognize hoarding incorrectly.
For organized hoarders (I am one) the hoarding doesn't begin as a result of being unable to maintain a current overfull environment.
Many of us entirely do. Neatly, cleanly, and with good living space. Some to a point of warehousing and spread sheets. It's still hoarding, and causes those suffering it huge problems. We clean and disinfect every spill, and haven't sunk to chaos, mess or dirt, yet we are hoarding huge numbers of items (often painfully) tidily. Not all with H/D continue acquisition, for some it is a phase.
Yes it is connected to control in one way or another.
But, it's important to note that hoarding doesn't begin, when people with more stuff than they can comfortably house, can't keep it in good order. It gets messy and problematic for all when that happens, but the idea that those of us who can do it tidily only begin to become hoarders if it subsequently gets messy, isn't correct.
