Dr Kylee Trevillion managed the ESMI study; a 5-year NIHR programme grant on the effectiveness of perinatal mental health services. In this interview from the ESMI Stakeholder Event, she speaks about two of the studies she was closely involved with: the DAWN study (RCT of guided self-help for women with depression), and a study looking at the acceptability of asking about mental health in antenatal booking appointments.
