The range of participants age was17 to 34 years old with a mean of 21.3. Ten of the participant (all females) were removed from the database with a self-reported history of anorexia nervosa. The data were analyzed using the SPSS with windows.

As far as ethical concerns all the participant were informed of the purpose of the study and had received the informed consent form to
