DescriptionPurpose of Project: Weight bias is one of the most prevalent forms of bias experienced and is associated with physiological changes in the body, contributor to obesity itself, and an indicator for increased mortality rates. Healthcare professionals are a common source of weight bias and those experiencing weight bias are receiving lower quality care. This project evaluated the effectiveness of an online course in reducing weight bias in healthcare professionals (HCP). Methodology: Healthcare professionals completed a self-paced, online educational course focusing on obesity, weight bias, and ways to reduce weight bias. The Attitudes Toward Obese Persons (ATOP) and the Beliefs About Obese Persons (BAOP) surveys were used to assess weight bias pre-and-post intervention. The Wilcoxon signed rank test was used to measure the effectiveness of the intervention by calculating the difference in survey scores pre-and post-intervention. Additionally, healthcare professionals’ intention to change their current clinical practice was assessed. Results: There was an increase in ATOP score post-intervention (W=9, z= -1.8857, p<0.05) and BAOP (W=0, z= -2.0226, p<0.05), indicating HCPs showed improved attitudes and beliefs (or less bias) towards patients with obesity. Additionally, HCPs expressed a more positive view towards treating patients with obesity and an intent to change their current clinical practice. Implications for Practice: This project demonstrated that obesity and weight bias modules can reduce weight bias in HCPs. Future research and quality improvement projects are needed to identify the impact of online training on quality of care and care seeking behaviors of patients with obesity.
