Now in its fifth edition, this seminal textbook for occupational therapy students and practitioners has retained the comprehensive detail of previous editions with significant updates, including the recovery approach informed by a social perspective. Emerging settings for practice are explored and many more service users have been involved as authors, writing commentaries on 14 chapters. All chapters are revised and there are also new chapters, such as mental health and wellbeing, professional accountability, intersectionality, green care and working with marginalized populations. Chapter 11 is written by two people who have received occupational therapy, examining different perspectives on the experience of using services. This edition is divided into clear sections, exploring theory and practice issues in detail. The first section covers the historical, theoretical and philosophical basis for occupational therapy in the promotion of mental health and wellbeing. The second section examines the occupational therapy process, followed by a third section on ensuring quality in contemporary practice. The fourth section offers insights into issues arising from the changing contexts for occupational therapy including an analysis of the implications for occupational therapy education. The fifth section has eight chapters on specific occupations that can be applied across the varied settings which are covered in the sixth and final section. Occupational Therapy and Mental Health is essential reading for students and practitioners across all areas of health and/or social care, in statutory, private or third (voluntary) sectors, and in institutional and community-based settings.Presents different theories and approaches Outlines the occupational therapy processDiscusses the implications of a wide range of practice contextsDescribes a broad range of techniques used by occupational therapistsProvides many different perspectives through service user commentariesCoverage of trust as part of professional accountability, leadership, green care, ethical practice using a principled approachAdditional and extended service user commentariesAn editorial team selected and mentored by the retired editors, Jennifer Creek and Lesley Lougher.
