Etcoff, Sabine Wilhelm Massachusetts General Hospital and Harvard Medical School, United States Received 28 February 2007; received in revised form 14 May 2007; accepted 17 May 2007 Individuals with body dysmorphic disorder (BDD) suffer from a preoccupation about imagined or slight appearance flaws. We evaluated facial physical attractiveness ratings and perfectionistic thinking among individuals with BDD (n = 19), individuals withobsessive-compulsive disorder (OCD; n = 21), and mentally healthy control participants (n = 21). We presented participants withphotographs displaying faces varying in facial attractiveness (attractive, average, unattractive) and asked them to rate them in termsof their physical attractiveness. We further examined how the participants evaluated their own physical attractiveness, relative toindependent evaluators (IEs). As predicted, BDD participants perceived their own attractiveness as significantly lower than did theIEs, and they rated photographs from the category ‘‘Attractive’’ as significantly more attractive than did the other groups.
Furthermore, both clinical groups were characterized by more perfectionistic thinking than controls. These findings mostly supportcognitive-behavioral models of BDD that suggest that individuals with BDD exhibit perfectionistic thinking and maladaptiveattractiveness beliefs.

According to this model, most people dislike found that individuals with BDD endorse beliefs, such as some aspects of their appearance, but individuals with ‘‘I have to have perfection in my appearance’’ BDD focus on these details, exaggerating their perceived or slight defects in appearance. Moreover, To our knowledge, facial attractiveness ratings and perfectionism have not yet been examined in BDD. In maladaptive beliefs about their attractiveness, such as the current study, we investigated whether BDD higher attractiveness standards and perfectionistic sufferers exhibit higher levels of perfectionism than thinking, which lead to a negative self-evaluation and control participants. Further, we investigated whether low self-esteem.

Thus, given that Based on clinical observations that BDD sufferers are individuals with BDD often compare their own often characterized by thoughts, such as ‘‘As long as I don’t look perfect, I won’t be able to be happy,’’ we expected that BDD participants would show levels of thinking and discrepancies between one’s own perceived inflated perfectionistic thinking, as has been shown in attractiveness and the perceived ‘‘ideal looking appear- ance’’ lead to more unfavorable social comparisons with However, because OCD is not characterized by a others.

So far, the current models of BDD arepredominately based on clinical observations. While there is some evidence that attention, interpretations ofsituations as well as emotion recognition are biased in The BDD group was comprised of 19 participants (six men) who met current DSM-IV ) criteria for BDD as determined by structured clinical interviews (Structured Clinical Interview for DSM-IV – Outpatient ).
