Dr. Christy's lab aims to foster health equity and promote cancer prevention and early detection behaviors (e.g., colorectal cancer screening, HPV vaccination) in order to reduce cancer incidence and mortality. Dr. Christy's research examines the associations between psychosocial factors, health beliefs, affect, healthcare access, patient-provider communication, and engagement in cancer preventive and early detection behaviors. Much of her research also involves evaluating the efficacy of behavioral interventions aimed at promoting cancer preventive and early detection behaviors
