Body Image: Is It a Useful Concept? (Maybe Not So Much)

I recently attended the International Society of Critical Health Psychology’s 8th Biennial Conference in Bradford, England. At the conference, I had the pleasure of attending many talks that challenged the way we approach health psychology. Luckily for me, there were several sessions that touched on issues of disordered eating and body image.

One such talk, a panel presentation with Hannah Frith, Sarah Riley, Martine Robson and Peter Branney, challenged attendees to re-think the way we approach body image. When I returned home, I immediately downloaded an article by Kate Gleeson and Hannah Frith (2006) that discusses this same idea and essentially begs the question: Is the concept of “body image,” as it is currently articulated, actually useful?

This might come off as a controversial question; after all, body image is central to many studies (and treatment programs) related to eating disorders. We’re told repeatedly … Continue reading →

How Much Can We Learn About Eating Disorders From Animal Research?

I have been studying the neurobehavioral aspects of food and drug reinforcement for the past 5 years (read more about it on my profile page). This involves using rats to mimic basic human behaviors surrounding food and drug intake. I then manipulate various neurotransmitter systems by using drugs and observe the effects this manipulation has on the behaviors I am interested in.

What’s important to this type of research is that we constantly challenge and evaluate the validity of using these animal models to study complex human diseases and disorders. Validity can be divided into several categories, but I’m going to focus on two in particular and relate them to an animal model of binge food intake.  These two types of validity are predictive validity and construct validity:

  1. Predictive validitywhen comparing animal research to human research, refers to the ability for some measure of animal behavior
