Winnie Gebhardt

Winifred (Winnie) A. Gebhardt studied at Utrecht University, The Netherlands, where she obtained her first degree in Clinical - and Health Psychology (Major), and Social - and Organizational Psychology (minor) in 1989. She did a post-Master research internship at Harvard Medical School in Boston, MA, USA in 1989. Upon return to the Netherlands, she worked in different health settings before starting her PhD in 1992 at Leiden University. In 1997, she obtained her PhD cum laude on a thesis entitled “ Health behaviour goal model: Towards a theoretical framework for health behaviour change." From 1997 she was employed as Assistant Professor, and as of 2006 as Associate Professor of Health Psychology at Leiden University. Over the past 20 years, she has worked on the development of health behavior change, resulting in her theoretical framework ("The Health Behavior Goal Model"). 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 intergoal facilitation and - conflict. Moreover, she explores intervention techniques to strengthen the link between a health goal and other personal goals, 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.

Veni-project: Alcohol on Social Networking Sites

This project investigates how much and why young adolescents talk about alcohol on Social Networking Sites (SNS), as well as the effects of alcohol-related Facebook posts on young adolescents´ alcohol consumption and when these effects occur. Subsequently, an intervention-plan will be developed and tested to counteract the detrimental effects of alcohol-related posts on SNS.
