RESUMO
Motivational deficits (little or no motivation to change) are often reported in patients with eating disorders, particularly anorexia nervosa. The motivational approaches frequently used by French clinicians rely solely on a dichotomous view of motivation (intrinsic vs. extrinsic). In self-determination theory, certain forms of extrinsic motivation can strengthen an individual's commitment to an activity, providing they are self-determined. This theory therefore extends and enriches the dual motivational approach by highlighting potentially useful forms of extrinsic motivation and by emphasizing the importance of behavioral regulation. Empirical work is now needed to assess how clinicians can use self-determination theory to enhance motivation to change among patients with anorexia nervosa and encourage their adherence to care management plans.
