Dr. Klassen’s research interests are in the social and psychological influences on inequitable distribution of medical care and related health outcomes. Her work uses a social perspective to examine the differences in experience of disease and illness and to identify components of individual experiences that are tied to broader social explanations and influences. This perspective is then applied to specific questions of disease outcomes and treatment access.Dr. Klassen’s primary focus has been in the area of cancer control, and spans the continuum of cancer control from primary prevention interventions to promote dietary change, to screening for early detection of breast, cervical, and oral cancers, to access to treatment, comorbidity and survival outcomes. This work synthesizes the influences of ethnic, social and geographic context, organizational behavior and policy, physician behavior, and individual patient behaviors. Other research in chronic organ failure and transplantion, HIV/AIDS, and immunization also examines social and behavioral influences on disparities.
