Dr. Hull specializes in strategic public health communication research and practice. Dr. Hull conducts theoretically based, practically useful, mixed methods research that improves health and reduces disparities in health through (mass) mediated communication. This research takes a double pronged approach, focusing on individual and social determinants of health.
Dr. Hull's research focuses on the design of persuasive messages promoting individual health behaviors. For example, her research examines the ways in which individual differences in disposition (i.e. perceived risk; sensaton seeking) regulate responses to gain- and loss-framed messages promoting HIV testing among young women of color. Dr. Hull worked also in collaboration with investigators from the University of Wisconsin Medical School to develop, implement and evaluate a tailored, computerized program promoting HCV risk reduction behaviors using mobile technology among people who inject drugs. This intervention uses motivational interviewing techniques to match intervention messaging to individual readiness for change and individual goals related to safer injection practices, overdose prevention and HCV testing. The HepNet platform is currently being adapted for the promotion of pre-exposure prophylaxis (PrEP) as a strategy for the prevention of HIV transmission among young gay men of color.
Dr. Hull's research also uses a social marketing approach to affect social determinants of health, HIV in particular. This line of research focuses on the construction, dissemination and evaluation of mass mediated messages designed to reduce homophobia in the Black community in Milwaukee. The campaign, Acceptance Journeys, takes a social marketing perspective to promote acceptance of LGBT people. This strategy aims to reduce the HIV/AIDS risk to which young Black MSM are exposed through multiple pathways by affecting this important social determinant of HIV risk. Dr. Hull leads Acceptance Journeys message design formative research, messaging strategy, message testing, and campaign evaluation (a 5 year rolling cross section with 3 comparison cities). This collaborative effort includes Diverse and Resilient, a community based organization, WI AIDS/HIV Program and Milwaukee Health Department.
