Researchers at the Centre for Behavioural Science and Applied Psychology are carrying out an evaluation of Mentalization Based Therapy for Parenting under Pressure (MBT-PP), a therapy for parents delivered by Tavistock Relationships. The Support for Inter-Parental Communication (SIPCo) project is studying the effects of MBT-PP compared to the usual support available in three local authorities: Bristol, Dorset, and Bournemouth, Christchurch and Poole. The project is funded by the Youth Endowment Fund.
