abstract

Individuals with eating disorders are said to be highly ambivalent towards change and thus have difficulty maintaining a commitment to, and motivation for, treatment. Self-Determination Theory postulates that Autonomous motivation for therapy exists when individuals view their participation as freely chosen.

OBJECTIVE:

The present study was designed to ascertain whether or not autonomous motivation was associated with treatment response in individuals with bulimia-spectrum eating disorders (BSED).

METHOD:

One hundred and fifty-five women with DSM-IV-TR BSED participated in multimodal group therapy and completed measures to assess motivation, eating and comorbid symptoms.

RESULTS:

Hierarchical multiple regression analyses demonstrated that higher levels of autonomous motivation at pretreatment predicted lower post-treatment scores on measures of eating preoccupations (shape, weight and eating concerns), binge eating, anxiety/depression, relationship to self and others and impulsivity.

DISCUSSION:

These results indicate that autonomous motivation may be an important predictor of outcome following treatment for BSED. Copyright © 2012 John Wiley & Sons, Ltd and Eating Disorders Association.
