Individuals who pursue bariatric surgery are motivated to improve their health and quality of life. To be successful, patients must make many changes to their eating and lifestyle habits. Dr. Wnuk's research focuses on identifying psychosocial factors that help individuals adjust to surgery, as well as on developing and testing behavioural interventions that can help with adjustment post-surgery. Her team has investigated a variety of topics including attachment style, mental illness, and eating disorders as they impact bariatric surgery patients. The interventions that Dr. Wnuk investigates include telephone-delivered Cognitive Behavioural Therapy and Motivational Interviewing; she is leading research on a group-based mindful eating intervention.
