Motivational readiness for treatment in weight control programs: the TREatment MOtivation and REadiness (TRE-MORE) test.

BACKGROUND AND AIMS: The degree of motivation before starting the treatment represents a pre-treatment predictor of successful weight management. The aim of this study is to develop and validate a new self-reported questionnaire of motivation and readiness to change before starting a lifestyle modification program (the TREatment MOtivation and REadiness test) (TRE-MORE) for overweight patients. METHODS AND RESULTS: TRE-MORE was evaluated in a consecutive series of 129 obese patients attending our Outpatient Clinic. Validation of the questionnaire was performed through test-retest reliability, internal consistency, psychopathological correlates, and concurrent validity. Subjects have been evaluated by means of a clinical interview, and different self-reported questionnaires, assessing the eating specific and general psychopathology, and quality of life. TRE-MORE total and subscales scores showed good test-retest reliability and internal consistency. We identified 10 items grouped in 3 areas (obstacles and desire to overcome, taking care of themselves, and sharing the problems, current lifestyle). TREMORE scores were significantly correlated with eating specific psychopathology and quality of life measures. Univariate and Receiver Operating Characteristic curve analysis showed that TRE-MORE total and subscales scores represent a good model for predicting a weight loss >5% of the initial weight after 6 months of treatment. CONCLUSION: TRE-MORE represents a validated and easy-to-use questionnaire assessing at the meantime the treatment motivation and readiness with good predictive capacity for weight loss.
