Dr. Fred Goodwin interviews Dr. Randy Frost, a leading researcher in the field of hoarding. Together with Dr. Gail Steketee, Dr. Frost contributed to a recent text book about Obsessive-Compulsive Disorder a chapter on hoarding and how to treat it ("Chapter 23") that many compulsive savers regard as their "bible." Dr. Frost is professor of psychology at Smith College in Northampton, Massachusetts. Dr. Frost defines hoarding as the acquisition and saving of unneeded items to the point that it causes significant distress, and says that sometimes hoarding can even preclude the use of furniture and spaces. For instance, a bed will be so filled up with things there's no room for someone to sleep on it. Or the hoarder will be unable to use the kitchen because the stove is covered with things and even the oven is full of things being saved. Hoarding is most often associated with Obsessive-Compulsive Disorder, which is an anxiety disorder. The anxiety is kept at bay as long as the compulsive saver avoids even thinking about throwing things out. Hoarding behavior is on a continuum, with symptoms ranging from mild to severe. Getting in the way of being able to organize and throw things out are problems in sustaining attention, categorizing possessions, a reliance on visual cues to trigger memory ("out of sight, out of mind"), and difficulties in making decisions. Interestingly, Dr. Frost says that the anxiety people experience in discarding items is often short-lived, citing one woman who wept about a book but was fully recovered from her grief about five minutes later. Treatment, he says, can help a hoarder learn to tolerate this kind of anxiety.
