About this webinar

This is a 90-minute webinar, that will focus on sharing the final research findings of the Circle of Security Intervention (COSI) Study.

The COSI Study was a four-year NIHR funded randomised controlled trial (RCT) that finished in February 2024, the study was co-lead by Dr Camilla Rosan and Professor Peter Fonagy. The study explored the clinical and cost effectiveness of a 10-session, group-based intervention called Circle of Security-Parenting (COS-P) for women in 10 different NHS perinatal mental health services (PMHS) across England. 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 compared COS-P, and COS-P and treatment as usual, to treatment as usual with a sample of 371 participants. The study collected data at four different time points (baseline, 3, 7, 12 months), including on participants mental health, emotion regulation skills, perceived parent-infant bonding, and infant developmental outcomes. It also videoed participants playing with their babies and coded these videos for parental sensitivity and attachment security. A qualitative survey was completed with 165 participants and a further 58 were interviewed to provide an in-depth of their experiences, 13 COS-P interveners also took part in focus groups.

The webinar will cover both the qualitative and quantitative findings of the trial and link these to research and clinical implications.

Aims of this webinar
