Values-based practice is a new approach to working with complex and conflicting values. It is based, primarily, on learnable skills and is being applied across a range of policy, training and service development initiatives in mental health and social care. This article outlines some of the key features of values-based practice including its complementary relationships to both regulatory ethics and evidence-based practice. We describe the systemic links between values-based approaches at the three key levels of policy, service development, prioritization and commissioning, and clinical practice and managing delivery of services, particularly as they are being developed in child and adolescent mental health services. Our article concludes by indicating some of the areas for further development of values-based practice.
