I passionately believe that patients must understand, accept and acknowledge that bariatric surgery is a collaborative approach. Surgery is an aid that enables patients to make lifestyle and behavioural changes.
My role is not a gatekeeper role in Assessing to exclude patients having surgery but rather to conduct a battery of Psychological assessments in the pre operative phase to assist in identifying individual strengths and weaknesses and then providing support, psycho education and if required, evidence based intervention. This approach enables patients to cope effectively with the transitions and make and sustain lifestyle and behavioural change to not only lose the weight, but most importantly develop skills to maintain the weight loss in the long term.

Title :Psychosocial presentation of Revisional and Primary bariatric surgery patients
Michele’s PhD research program focused on identifying the causes of weight-loss failure for primary, revisional and multiple revisional bariatric-surgery patients.
The research examined the patients' psychosocial functioning and their perceptions of the psychosocial factors that had contributed to these outcomes. The studies confirmed the importance of understanding primary and revisional bariatric surgery patients' needs and vulnerabilities, and identified not only their unique psychosocial factors but combinations of factors, and, the increase in intensity of factors that explained these patients' weight loss trajectories. Michele has published four peer reviewed journal articles.
