Psychological techniques help reduce body dissatisfaction in women with bulimia nervosa

Jan 21 2016

Researchers from the University of Granada have proven that there are two psychological techniques that help reducing body dissatisfaction and its associated symptoms in women with bulimia nervosa, both of them based in the exposure of their bodies in a mirror.

The researchers' work, published in Journal of Behavior Therapy and Experimental Psychiatry magazine, has revealed that both techniques also reduce salivary cortisol levels, a steroid hormone released in response to stress.

UGR researchers compared two different techniques: guided exposure (in which the participants must observe their bodies in the mirror while they describe it in a neutral and objective way, as if an artist should draw them without seeing them), opposite to pure exposure (in which the participants must observe their bodies in the mirror too, but they can express the thoughts and feelings this sight produces in them).

The research counted with the participation of 29 women with high body dissatisfaction and diagnosis of bulimia nervosa, which were randomly divided in two treatment groups, one for each technique. Each women received six exposure sessions. Changes in their feelings (both positive and negative) were assessed, as well as their body satisfaction and changes in salivary cortisol levels.

Effective techniques

The main results show that both exposure techniques reduce negative thoughts in bulimic women and boost positive ones over the course of the treatment, and also reduce cortisol levels. However, pure exposure increases body satisfaction more than the other one and reduces to a greater extent the subjective discomfort caused by the sight of one's body during sessions.

These data suggest that pure exposure "could be an effective therapeutic strategy for reducing body dissatisfaction in people with eating disorders and, in a preventive way, in women with high body dissatisfaction levels. Nevertheless, in the future, we should delve into the change mechanisms through which this technique is working", explains the lead author of this paper, UGR researcher Sandra Díaz Ferrer.

Body dissatisfaction is one of the main factors responsible for developing and keeping eating disorders. "What alerts us the most is that we are facing high body dissatisfaction levels in women of all ages more often. That's why it's important to develop effective techniques for increasing body satisfaction and preventing the appearance of its most feared consequence: the eating disorders".

One of the most studied techniques for improving body satisfaction of the last decades is the exposure to one's body. "The general goal in this kind of technique is to expose people to the image of their own bodies in a mirror big enough to let them systematically examine every inch of their bodies within a time period and to let them learn how to manage negative thoughts and feelings in a more constructive way, without avoiding them", Díaz Ferrer explains.

The results of this work indicate that the use of techniques that allow to express the negative thoughts and feelings associated with one's body could be more effective that those that guide the patients through neutral descriptions of their bodies.

"With this research, we don't expect women to change their bodies, but to let them be able to accept them and to love them as they are. We should not let mirrors to be enemies in which we can only see what society tells us is beautiful. The mirror should be the mean to reflect the light that every person has, something that ignores fashion or beauty ideals", the researcher from the UGR concludes.
