I am an assistant professor in the Department of Social and Behavioral Sciences at Yale University School of Public Health. I have expertise in community-engaged research, qualitative methods, adolescent health, and intervention adaptation and implementation. The overall goal of the proposed research is to explore the process of sexual and reproductive health communication between grandparents, parents, and children in multigenerational and skipped–generation households. Using both quantitative and qualitative research methods, this project aims to (1) describe how grandparents support (or could support) their grandchildren’s family planning knowledge, attitudes, use of contraception, and psychosocial determinants of sexual wellbeing (2) evaluate the intergenerational transmission of reproductive health communication patterns between grandparents, parents, and children, and (3) identify what individual and interpersonal traits predict quality grandparent-grandchild reproductive health communication. As the US population living in multigenerational households continues to rise, understanding grandparents’ role in youth’s sexual and reproductive health decision-making becomes increasingly important. This proposed body of research builds on our current understanding that positive sexual and reproductive health communication with trusted adults can reduce youth’s likelihood of sexual risk-taking behaviors (including unprotected sex). Findings will move the field forward by determining how grandparent-led communication can be strengthened and can inform the adaptation of sexual and reproductive health interventions involving parents/guardians that wish to also involve grandparents. Findings have the potential to greatly improve grandparent-child communication, helping us reach our long-term goal of youth’s increased access to contraceptive services and pregnancy decision-making power.
