This introduction presents an overview of key concepts discussed in the subsequent chapters if this book. The book aims to consider the nature of cognitive-emotive-behavioural coaching (CEBC). Coaching approach is useful for a coaching definition to make clear what approach to coaching is being taken. Development-focused cognitive-emotive-behavioural coaching (DF-CEBC) concentrates on areas of coachee development and is flexible and pluralistic in nature. Development-focused CEBC as defined here has two areas of focus. The primary focus is on coachee development. The secondary focus is on obstacles that coachees encounter along the path towards their development-based objectives and on any problematic responses to the objectives. The objective of DF-CEBC is for coachees: to achieve development-based objectives in one or more life domains, and to address the obstacles that are encountered as they pursue these objectives and their problematic responses to these obstacles.
