In a study just released in Behaviour Research and Therapy, Anna Shusterman, Lauren Feld, Lee Baer, and Nancy Keuthen
(2009) utilized data from a massive online survey to examine the role
that emotions play in prompting and sustaining this disorder. The
description of TTM in the DSM-IV-TR as well as a number of prior
studies have linked TTM behaviors with a sense of relief on the part of
the individual exhibiting the behavior. In other words, many
individuals have reported that pulling out their own hair has resulted
in immediate decreases in negative emotions. Despite this potentially
valuable function, the behavior also includes a variety of less
comfortable correlates, namely subsequent feelings of shame and guilt
and a strong desire to cease the behavior. So, the behavior becomes
rewarding through its ability to quickly reduce certain negative
emotions, but also results in several emotional and social consequences.
