4Pi Involvement Standards 4Pi is a framework for the involvement of service users and carers - in our own care, in our communities, in service delivery and evaluation and in organisational governance and strategy. 4Pi is a simple framework on which to base standards for good practice, and to monitor and evaluate involvement. The framework builds on the work on many people: mental health service users and carers and others who have lived and breathed involvement and shared their experiences in various ways, both written and unwritten. Meaningful involvement means making a difference: it should improve services and improve the mental health, wellbeing and recovery of everyone experiencing mental distress.
