Assessing Weight Stigma: Validating Attitudes and Beliefs Questionnaires Among Future Healthcare Professionals

Background This study aimed to establish the reliability and validity of the Anti-Fat Attitudes (AFA) questionnaire and the Beliefs About Obese Persons (BAOP) scale. Methodology A convenience sample of 257 students from three distinct sections of the University of Medicine and Pharmacy "Grigore T. Popa" Iasi (Medical Faculty, Nutrition and Dietetics, and Nursing) participated in an observational study. Construction validity was tested with exploratory factor analysis. The students completed a form containing sociodemographic data, the AFA questionnaire, and the BAOP scale. Weight and height were self-reported and used to determine the body mass index. Results The value of the Cronbach alpha coefficient for the AFA questionnaire indicated adequate internal consistency (0.862). The exploratory factor analysis identified the following three factors corresponding to the original questionnaire: Dislike, Fear of Fat, and Willpower. We validated a single-factor structure of the BAOP scale, which had adequate internal consistency (0.781). There were statistically significant differences (AFA: p = 0.02; BAOP: p = 0.03) between the scores of the students from Nutrition and Dietetics, Nursing, and General Medicine. Conclusions This study demonstrated that the AFA questionnaire and the BAOP scale could be used to evaluate weight stigma in healthcare students, providing a useful tool to assess the effects of weight stigma awareness interventions in this population.
