A survey was applied involving three indicators (factors): a) preference/ rejection, b) concern/disinterest) and c) will/apathy.

Results: Construct validity, after Varimax rotation showed 14 questions: a) preference /rejection (4 questions), b) concern/disinterest (6 questions) and c) will/apathy (4 questions). The variance for each factor was 23.5%, 41.0% and 24.1%, respectively totaling 88.6% of explanation. The reliability showed highly reliable values, ranging from 0.73 to 0.75 for each factor. The scales developed from the LMS method showed the following cutoffs points: p <10 is low attitude, ≥p10 to p90 moderate attitude, p90 to p97 high attitude and ≥p97 very high attitude to obesity.
