Sarah Novak, Ph.D., is an Assistant Professor in the Psychology Department at Hofstra University. Dr. Novak conducts research exploring the impact of personal relationships, especially marriage, on health behavior and psychological well-being. Her recent studies examine social control, or people’s attempts to regulate their partner’s diet and exercise behavior. Her research has demonstrated that these attempts at regulation can be effective in promoting positive changes, but they can also exact a psychological cost, especially in the context of low-quality relationships.
