Originally entitled 'Mental Health Needs of Children and Young People with Learning Disabilities', this new edition focuses on the care and support of those with moderate and severe intellectual disabilities. In addition to bringing the content fully up to date, the editors, both longstanding experts in this field, have commissioned the most experienced contributors from relevant disciplines to address topics such as forensic issues and risk assessment, transition and functional analysis. The importance of developing evidence-based practice is a key theme of the book, acknowledging its key role in helping professionals and practitioners to provide high-quality personalised care for children and young people with intellectual disabilities who have mental health needs. The book provides health and social care professionals with a sound knowledge base for shaping and enhancing their practice, along with the confidence to improve the outcomes for these young people. Each chapter includes short case illustrations, examples of good practice, reflections on current practice, key learning points, references and key websites for further exploration.
