Differences between IQ and school achievement in anorexia nervosa

Anorexia nervosa is a multidimensional syndrome in which perfectionistic striving appears as a common component of the symptom cluster. Multiple studies have linked this character trait to attempts to achieve a "perfect" weight. In contrast, no empirical data are available that document perfectionistic striving outside of food and weight themes. The present study (N = 20) looked for evidence of perfectionistic striving in school behavior by comparing school achievement and IQ scores. School achievement was found to be significantly greater than would be predicted by IQ scores. This finding and directions for future research are discussed.
