Health literacy research

Cath’s health literacy research explores how people access, understand and make sense of information to make decisions about their health; for example, about choosing food for their family. Her work helps the NHS and other health organisations tailor their services for people with different levels of health literacy.

Childhood immunisation research

Cath’s work in childhood immunisation focuses on understanding the information and decision-making support required by parents in relation to vaccinations for their children. She conducts research to help NHS organisations understand what parents want to know about vaccines and to advise health professionals on how best to support them. As well as conducting the necessary research, Cath has been involved in designing programmes to increase the take-up of childhood vaccinations, including developing a web-based decision aid for parents thinking about the MMR (measles, mumps and rubella) vaccine.

She is experienced in using different approaches to build trustful relationships and has worked closely with gypsy and traveller communities, families living in poverty and individuals with long-term health conditions.
