Book excerpt: This is a comprehensive textbook on child and adolescent psychotherapy. It is suitable for students at graduate, postgraduate and advanced undergraduate levels. It will also serve to inform experienced practitioners about the latest developments in the field. Bringing together concepts and methods from psychodynamic, behavioural, cognitive and developmental perspectives, it provides an integrative conceptual model and therapeutic approach for conducting psychotherapy with children and adolescents troubled by a wide range of psychological and cognitive difficulties, including ADHD and learning disorders. The integrated model and rationale described seeks to stimulate students and experienced clinicians alike to step out of the present-day, conceptually segregated world of psychotherapy and into a world of psychotherapy unbounded by narrow theoretical orientations.
