According to the U.S. Department of Health and Human Services, bariatric surgery is currently the best option for long-term weight loss for obese patients. Health behaviors post-surgery play an important role in providing a better overall quality of life for the bariatric patient. Successful treatment outcomes rely on patient adherence to medical advice and health protocols. Research that examines factors that interfere with long-term adherence to dietary guidelines post-bariatric surgery is critical for improving outcomes. The focus of this study was to assess the relationship between patient activation, anxiety, and perceived adherence to dietary guidelines in a sample of 44 participants who completed bariatric surgery. Participants were asked to complete an online survey comprised of several items taken from standardized screeners measuring patient activation and anxiety, as well as a selection of items taken from general dietary guidelines to measure perceived adherence. The collection of items within the survey also included supplementary questions related to each factor being analyzed. Results of statistical analysis performed in this study using multiple linear regression showed no relationship between patient activation, anxiety, and perceived adherence. Findings suggest a need for further investigation of patient adherence post weight-loss surgery within the bariatric population.
