Examining the self is at the heart of coaching and this book provides a comprehensive overview of knowledge on the Self from psychology, philosophy and other disciplines. Developmental Coaching outlines a theory of individual development, with practical applications for coaches. The Development of Self in Action (DSA) theory provides a credible explanation of the individual functioning, desired changes and development that makes developmental coaching a rigorous, theory-based approach to practice.

This new edition also offers an additional section on professional development and coaching
