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.
