The association between interpersonal problems and treatment outcome in the eating disorders: A systematic review.

OBJECTIVE

To review systematically the eating disorder literature in order to examine the association between pre-treatment interpersonal problems and treatment outcome in people diagnosed with an eating disorder.

METHODS

Six relevant databases were searched for studies in which interpersonal problems prior to treatment were examined in relation to treatment outcome in patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN) or eating disorders not otherwise specified (EDNOS).

RESULTS

Thirteen studies were identified (containing 764 AN, 707 BN and 48 EDNOS). The majority of studies indicated that interpersonal problems at the start of therapy were associated with a detrimental treatment outcome.

CONCLUSIONS

Individuals with a binge/purge-type of eating disorder may be particularly vulnerable to interpersonal issues and these issues may lead to poorer treatment recovery by reducing the individual's ability to engage in the treatment process on a functional level. The clinical and research implications are discussed.
