This work will form the basis of one Work Package in a larger body of work submitted for funding to the NIHR around the experience of childhood sexual abuse (CSA), adult sexual assault, its impact on the birth experience, and subsequent perinatal mental health and wellbeing. Currently there are is no large quantitative evidence on the interaction between previous experience of sexual violence, birth experience and perinatal mental health and thus this piece of research will begin to build an evidence based by utilising already collected data on sexual violence, thus reducing burden upon survivors of assault. In doing so we aim to establish the size and nature of the problem. This work will then feed into a larger body of work with the providing services that meet the needs of survivors of sexual abuse and assault.
