Trichotillomania Study: Reneta Slikboer

Submitted by Adam Szmerling on 8th Oct 2014

A little known condition called trichotillomania (otherwise known as compulsive hair pulling) was once thought of as rare. This is no longer the case with estimates ranging from 0.6% to 3.4 % (Christenson, Pyle, & Mitchell, 1991). This means that approximately 285,000 individuals in the state of Victoria have firsthand experience of hair pulling. This psychological disorder is taken seriously by researchers and clinician’s around the world as many studies have shown how debilitating it can be.

Dealing with hair pulling can be tough

Everyday life can be made difficult by hair pulling including: academic, work, and social areas (Woods et al., 2006). Feelings of shame, irritability, lack of control and low self-esteem are often also experienced (Casati, Toner, & Yu, 2000; Rehm, Nedeljkovic, & Moulding, 2012). Many people may not have heard about hair pulling and even trichsters (an affectionate light hearted name for people with trichotillomania) may not know that it is a recognised disorder with existing treatments.

Researchers are working on it

There are a few models in which to make sense of hair pulling on a psychological level. The Comprehensive Behavioural Model is a flexible model whereby the individuals symptoms can be conceptualized on different levels, including internal and external stimuli (Mansueto, Golomb, Thomas, & Sternberger, 1999). Hair pulling has also been thought of as a way to maintain a desirable level of arousal (Penzel, 2008) which in turn influences one’s social environment (Franklin, Tolin, & Diefenbach, 2006). Thinking about hair pulling within these models can be helpful to make sense of a diverse range of implicated elements.

Hope for a better understanding

Research being conducted at the Swinburne University of Technology is aimed at developing a psychological model of trichotillomania based on quantitative data. It is hoped that with a model developed on rigorous statistical tests, a better understanding of motivation will be generated. Such knowledge will help with the development of more effective treatments.
