In 1997, she obtained her PhD cum laude on a thesis entitled “ Health behaviour goal model: Towards a theoretical framework for health behaviour change."

Winnie Gebhardt's main research interest lies in the development of theory to explain, predict and influence health behavior. Specifically, she studies the dynamic interaction of health and other personal goals, including the role of ambivalence, goal prioritization, intergoal facilitation and - conflict. Moreover, she explores intervention techniques to strengthen the link between a health goal and other personal goalspersonal identity, e.g. by connecting the health goal to future "possible" selves, or by boosting “transitional identities”, and/or by applying techniques to reduce goal conflict and ambivalence. In addition, she works on the evaluation of the effects of (governmental) interventions to encourage healthier lifestyles, and on the improvement of the process of intervention implementation.
