One common misperception about weight management is that bariatric surgery, dietary management and pharmacological
treatment “cure” obesity and automatically lead to the behavioural changes which are needed to maintain weight loss,
that is to say, some patients might think that transient weight loss will automatically become permanent. The self-regulation
theory suggests that the beliefs a patient hold about his or her own illness determines how he or she will deal with it. Illness
beliefs can be assessed through the revised illness perception questionnaire (IPQ-R), a non-specific illness questionnaire. In a
previous work, we made an obesity-specific version and a cross cultural-adaptation of the IPQ-R to Spansih language, however,
its psychometric properties remain to be studied. The present work aims at assessing construct validity and reliability of the
Spanish language version of the IPQ-R in patients with obesity. Construct validity refers to the degree to which the questionnaire
items actually measure different types of beliefs and not other constructs. Whereas Chronbach’s alfa index of reliability refers
to the degree to which the test items are correlated with one another (internal consistency). Our study involves applying the
questionnaire to 700 Mexicans with obesity (IMC>30). Having a valid and reliable instrument to measure patients’ personal
models of obesity might be useful for ensuring patient-health provider communication, guaranteeing comprenhension of
treatment implications by patients, identifying misperceptions that will need to be corrected and even help predict patient
engagement and behaviour changes.
