Abstract
Objective: To assess motivation to change in adolescent patients with bulimia nervosa through the Bulimia Nervosa Stages of Change Questionnaire (BNSOCQ), an instrument adapted from the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ) already validated in anorexic patients. Method: Subjects were 30 bulimia nervosa patients (mean age=16.3 years) who were receiving treatment at an eating disorders unit. The evaluation instruments were: the BNSOCQ, the Eating Disorders Inventory (EDI-2) and the Beck Depression Inventory (BDI). The BNSOCQ was re-administered 1 week later to evaluate test-retest reliability. Results: The BNSOCQ demonstrated good internal consistency (Cronbach's alpha = 0.94) and one week test-retest reliability (Pearson's r = 0.93). Negative significant correlations were found between the BNSOCQ and several EDI-2 scales (Pearson's r between -0.51 and - 0.84) and the BDI (r= -0.74). Conclusion: The study provides initial support for the reliability and validity of the BNSOCQ as a self-report instrument for assessing motivation to change in adolescents with bulimia nervosa.
