The relation between eating disorders and components of perfectionism.

OBJECTIVE

The authors' goal was to explore the relation between perfectionism and psychopathology, including eating disorders.

METHOD: Using logistic regression, the authors calculated odds ratios for the associations between perfectionism subscale scores and psychiatric disorders in 1,010 female twins who completed the Multidimensional Perfectionism Scale and participated in diagnostic interviews.

RESULTS

Elevated concern over mistakes was associated with anorexia and bulimia nervosa but not with other psychiatric disorders. Doubts about actions was associated with eating and anxiety disorders. Multivariable models confirmed that higher scores on the subscales for concern over mistakes and doubts about actions were most strongly associated with eating disorders.

CONCLUSIONS

The aspect of perfectionism captured by scores on a subscale measuring concern over mistakes may be particularly associated with eating disorders and not generically predictive of psychopathology.
