This book offers a comprehensive overview of formulation applied within the mental health nursing context. It presents a contemporary outlook on the role of the mental health nurse, exploring and reflecting on the foundational values-based and person-centred principles of mental health nurse education and practice. Through this timely and accessible textbook, the authors demonstrate how a variety of theories can be used to enhance formulation in practice, ensuring mental health assessment and intervention are meaningfully connected to support patient recovery. Including service user experiences and viewpoints throughout, each chapter also benefits from tailored discussion points to enable learners to develop critical thinking around formulation. An invaluable guide to the field, it provides a clear, up to date and thought-provoking overview of formulation, essential for students and practitioners in clinical psychology or psychotherapy, as well as clinicians working in all areas of mental health and social care, psychology, therapy, and counselling.
