Assessing motivation to change in bulimia nervosa: the bulimia nervosa stages of change questionnaire
Open accessAbstract
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.

The Bulimia Nervosa Stages of Change Questionnaire validation study conducted in Spain demonstrated good internal consistency with Cronbach's alpha of 0.94 and one-week test-retest reliability of 0.93.
“In turn, the validation study of the BNSOCQ, which was conducted in Spain, demonstrated good internal consistency with Cronbach’s alpha of 0.94 and one-week test-retest reliability of 0.93 [42].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
