In the DSM-5 Trichotillomania (Hair Pulling Disorder) and Excoriation Disorders (Skin Picking Disorder) are included in the Obsessive-Compulsive and Related Disorders section. Each of these disorders is present in about 1-2% of the population. They are common in females and share some similarities with Obsessive Compulsive Disorder (OCD). It generally starts before adulthood but can start later.
Take steps to detect
In my practice, at least 9 out of 10 times only direct questioning reveals these problems. It is often present along with other anxiety disorder even though the literature mainly comments on its co-occurrence with OCD.
It is very treatable
For something so treatable (and relatively common) it is surprising that there are not many intervention studies. These conditions respond very well to cognitive behavioral therapies, and although useful, medication treatment has not shown robust evidence (Bloch et al., 2007; Lochner, Roos, & Stein, 2017; Rothbart et al., 2013).
What and how to treat
The literature chiefly talks about habit reversal treatment as if skin picking is a habit only. There are both habitual and compulsive elements to these conditions, and they require specific attention. Differentiating between these two phenomena is important.
So, a combination of habit reversal and other cognitive behavioral strategies are needed for their effective management.
Practice makes it perfect
No matter how much one reads about the treatments, it is best to have hands-on training. This is because most mental health training programmes do not cover this condition in adequate detail.
Our workshops hope to provide busy clinicians with just the right skills to help people who have either of these conditions.
