What Is the Impact of Overvaluation on Binge Eating?

Overvaluation is the term used to describe an emphasis on body image and the influence of this valuation on a person’s self-esteem. In some psychological problems related to eating, such as anorexia nervosa and bulimia, overvaluation is one of the diagnostic criteria and helps clinicians identify the symptomology of the problem.

However, for binge eating (BED), overvaluation is not currently listed as a diagnostic and clinical feature. But should it be? That was the question asked by Carlos M. Grilo, PhD, a Professor of Psychiatry and Director of the Program for Obesity, Weight, and Eating Research (POWER) at the Yale University School of Medicine in Connecticut. Grilo recently chose to explore how overvaluation affected treatment outcome in a way that has not been examined before.

Existing research on BED and overvaluation has only looked at brief follow-ups to determine overall progress. Grilo decided instead to follow up for an entire year after an intensive six month group treatment for BED. He assessed 90 participants before they began either cognitive behavioral therapy (CBT) or behavioral weight loss therapy (BWL). Grilo interviewed them again at the end of the 12-month follow-up period

Grilo found that the 58% of participants who presented with high levels of overvaluation had worse outcomes when compared to those without overvaluation behaviors. This finding persisted even when Grilo accounted for self-esteem and depression. The lower response rate and poorer outcomes in the overvaluation participants were evidenced by more episodes of binge eating and persistent overvaluation.

Grilo believes that this research demonstrates the clinical significance of overvaluation in the diagnosis and treatment of BED. Although this research cannot determine whether it warrants inclusion in the DSM-V, it does suggest that overvaluation should be considered as a subcategory or distinctive feature of BED that has bearing on treatment outcome. Grilo added, “The presence of this cognitive feature could signal to clinicians a more disturbed variant of BED, thus alerting them to patients who might require greater attention.”

    Maybe it’s the name of the treatment that’s throwing me off but any time you “over” do something that doesn’t necessarily signal healthy does it? So In terms of making someone who is already struggling with an eating disorder have to concentrate on the areas like body image and self esteem where they already most likely struggle quite a bit, this seems a little like it could be like rubbing even more salt in the wound.v8zu

    Sadly, I look at all of the images that are given to young women and men today about what is acceptable and coveted when it comes to body size and what is not and I wonder how more of us don’t struggle with eating disorders. It is seriously messed up when they show us models who are a size 00 and tell us that this is the ideal of what beauty is when in reality there are like 5 women in the world who even meet this standard! I think that we all kinf of need a little bit of a wake up call because this is doing serious damage to the psyche of so many beautiful young men and women and causing them to put their health at risk to try to obtain something that for most of us is not really obtainable.
