This volume comprises a collection of critical essays on current concepts in occupational therapy. These essays do not constitute a definitive account of the current state of thinking in occupational therapy. They are intended to stimulate interest in academic debate and to provoke a critical response. The essays reflect how as the profession of occupational therapy has matured, it has developed its own theories and principles based on an awareness of the human need for a balanced but chnaging range of activities throughout life to support health and wellbeing.
