Whetten's research examines the health behaviors and outcomes of disadvantaged communities and individuals. They seek to understand the interrelationships among individual and community psychosocial dynamics, health behaviors, health, provider characteristics and public policies. Whetten views these relationships as multidirectional. They examine and clarify underlying group characteristics that can be addressed to improve individual and community well-being. Whetten is one of a small group of researchers examining adult health outcomes as they relate to a life-course of events and influences starting with childhood experiences within families and communities and continuing through present-day conditions that may be manipulated through intervention.
