This book describes an approach to children and young people who might be helped by child psychotherapy. Attention is paid to factors within the child's personality, to strengths and impediments in the developmental process, and to the family and wider school and community context. Individual chapters address both clinical methods and a variety of clinical problems, including work with very young children and their parents, severe deprivation and family breakdown, developmental delay, and the more serious psychological illnesses of childhood. Assessment in Child Psychotherapy is a significant contribution to all mental health professionals who need to be able to identify the precise nature of a child, adolescent or family's problems and to offer the most appropriate help. Such a book is long overdue. It spans a range of thinking about how best to reach those whose emotional and behavioural difficulties pose challenging questions as to the most suitable forms of treatment.
