This book shows how psychological and social interventions can help people with psychosis. It brings together both theoretical chapters that contribute to the reconceptualization of psychosis and clinical cases illustrating how contemporary psychotherapeutic intervention models can be applied in the treatment of this mental health condition, with reflections, strategies and practical guidelines demonstrating how these models can inform professional practice in mental healthcare.   Chapters brought together in this volume aim to reflect a paradigm shift in psychosis care. They present person-centered models that lead to a way of seeing, understanding and treating psychosis that is very different from the traditional biomedical model. Current authors and approaches are revolutionizing an outdated model trapped in purely pharmacological actions and tautological explanations of a biological nature, where symptom control is the basic and fundamental form of approach, and in which psychotherapeutic actions take second place as subsidiary to the former. Approaches such as Acceptance and Commitment Therapy, Acceptance and Recovery Therapy by Levels, Open Dialogue, Compassion-Centered Therapy or the Hearing Voices movement, to name but a few of those presented in this book, represent a journey of self-knowledge and learning for those recovering from psychosis, and have an intense transformative potential for the therapeutic team. The fundamental principle that guides this book is to share models belonging to psychology that aim at personal development while respecting the needs, values and goals of each person, and that can be adopted by any professional or student of clinical psychology, psychiatry, nursing, social work or any other discipline searching for more humanistic approaches to treat psychosis.
