The Circle of Security Intervention (COSI) Study
The Circle of Security Intervention (COSI) Study is a four-year National Institute for Health and Care Research Health Technology Assessment funded randomised controlled trial (RCT). The study seeks to explore the clinical and cost effectiveness of a 10-session, group-based intervention called Circle of Security-Parenting (COS-P) for women in NHS perinatal mental health services (PMHS). COS-P is an intervention designed to help parents manage their difficult emotions and understand the impact of these on the parent-child relationship.
The trial will involve nine PMHS across England and will compare COS-P to treatment as usual with a sample of 369 participants.
Research Question: Is the Circle of Security-Parenting programme more effective than treatment as usual in improving perinatal mental health difficulties and parent-infant bonding for parents in NHS perinatal mental health services?
