Her research has changed policy and practice, including EU guidance on chlamydia screening, and informed the RCOG’s strategy for women’s health care (2011), the RCP’s report on alcohol and sexual ill-health (2011) and CONSORT guidelines for non-drug randomised trials. Her current research focus is on improving use of contraception, how women plan and prepare for pregnancy and how early intervention can improve women and child health across the life course.

She received the UCL prize for Leadership in Public Engagement in 2012 and an NIHR Senior Investigator Award in 2014.

Dr Corinne Rocca

Associate Professor, Epidemiologist

Corinne Rocca is an Epidemiologist at UCSF’s Bixby Center for Global Reproductive Health. Her research interests include prevention of unintended pregnancy, adolescent sexual behaviour, contraceptive use, pregnancy intentions, and latent variable measurement. Dr. Rocca’s research has focused on the measurement and significance of pregnancy intentions, including what influences young women’s attitudes towards pregnancy and the role of intentions and ambivalence in shaping contraceptive behaviour. She is particularly interested in using quantitative psychometric techniques, such as Item Response Theory, to improve measurement of latent variables, including attitudes and social norms. Her current work includes creating a valid measure of childbearing attitudes for use among diverse populations of adolescents and young women; using data from a nationally representative sample of unmarried young people to examine the roles of pregnancy ambivalence and fatalism on use of effective contraception; and examining barriers to safe abortion in Nepal.
