Many of us are reluctant to throw things out.
We buy. We accumulate. We collect. Eventually our attics are packed with dusty heirlooms that we rarely, if ever, look at. Eventually we’re forced to pare down and head to the Goodwill.
But not all of us.
Hoarding – or the prolonged difficulty of discarding unneeded possessions – is pervasive in our culture, affecting nearly 3% of the population. This compulsive collecting, and unwillingness to part with “stuff,” is even the subject of multiple popular television series.
How do you conceptualize hoarding behavior?
The core feature of hoarding is the inability to throw things away. This can be due to many different reasons, whether there’s a strong sentimental attachment or the belief that you will need these items one day. Compulsive buying is often involved, and inevitable clutter.
How was hoarding first conceptualized among psychiatrists and psychologists? And when did the term first enter the lexicon?
It was originally conceptualized as a difficult-to-treat subtype of obsessive-compulsive disorder (OCD). A lot of that work identifying this subgroup was going on in the late 1980s and early 1990s. There was a small but growing group of researchers demonstrating that this is fundamentally different from OCD in several ways.
In terms of the clinical presentation, the comorbidity patterns are different from those for OCD. And the course is a little bit different; we see a progressive development across the lifespan, as opposed to a clear-cut diagnosis earlier in life, as is typically seen with OCD. By the time a lot of people seek treatment, they’re often being brought in by, say, family members when they’re a little bit older. With hoarding, there is also this consistent pattern of poor treatment response across the board, whether to selective serotonin reuptake inhibitors or behavioral therapy.
A lot of this work together led to advocacy for recognizing hoarding as an independent diagnosis in the DSM-5. I think official recognition by our “big book” prompted more attention to this population. Previously these patients probably would have been diagnosed with OCD, and it really isn’t appropriate to think of hoarding as purely an anxiety disorder.
Hoarding exposure and future mental health
You have a new study, published in Annals of Clinical Psychiatry, looking at mental health among adult children of parents with hoarding problems. Can you tell us what inspired you to run this study, and what you found?
There were a couple of factors.
We’d seen a lot of folks with hoarding in OCD specialty clinics, so my clinical experiences with this population certainly drew me to this general area. But then, at the same time, I have this broad training in child mental health. And childhood trauma or adverse childhood experiences, which can include being around hoarding, can be a very difficult thing to live through and deal with. And here I have to give a lot of credit to Suzanne Chabaud, PhD, of the OCD Institute of Greater New Orleans, who’s one of the coauthors on the paper. She’s been beating the drum of thinking about the family and kids of people with hoarding disorders for years. My interests came from some of those experiences, but she had the good idea of really looking at this problem in a detailed way.
