INTRODUCTION: Lifestyle intervention is mandatory for obesity treatment. The aim of this study is to design a questionnaire to describe and quantify those behaviours more closely related to obesity in the Spanish obese population. METHODS AND PROCEDURES: An expert panel designed a preliminary 57 Liker-type item questionnaire, which was self-administered to 335 overweight patients (110 male, 225 female; age, 42 +/- 14 years; BMI, 32.6 +/- 3.7 kg/m2). After a subjacent dimensionality searching and item reducing first phase, a shrunk questionnaire of 24 items was then self-administered to 156 overweight patients (52 male, 104 female; age 42 +/- 12 years; BMI, 33.1 +/- 3.5 kg/m2); 56 of those patients were re-administered the questionnaire in order to provide test-retest information. RESULTS: Final questionnaire includes 22 items clustered in five dimensions: diet caloric intake, searching for psychological well-being eating, physical activity, healthy eating and alcohol intake. Proposed factorial structure is mostly reproduced in different samples and using different extraction methods: all dimensions but alcohol intake score alpha values > 0.75 for liability; test-retest stability is greater than 0.90 in all dimensions but alcohol intake; results for all validity tests performed (of construct, of content and discriminative) are highly satisfactory. CONCLUSION: Metrics study results (liability and validity) demonstrate that the proposed questionnaire provides an excellent tool to assess those lifestyles related to obesity control.
