The chapter broadly chronicles the evolution of behaviour therapy from early 1900s till date.
Chapter 2 of part I has extensively dealt with basic concepts for understanding behaviour therapy.
The Chapter on Psychobiological Basis of Behaviour Therapy highlighted the symbiotic relationship between physiological and psychological aspects as the scientific basis for behaviour therapy.
The author while discussing Developmental Perspectives in behaviour therapy has cautioned the practitioners to take extra care in applying behaviour therapy on children.
Part II of the book extensively deals with the techniques of behaviour therapy in eight separate sections.
The section on Techniques of Behaviour Therapy, in fact, serves as a handbook for practitioners as well as aspirants in the field of behaviour therapy.
In line with overseas trends, cognitive behaviour therapy was also readily accepted in Aotearoa/ New Zealand among psychological practitioners and consumers (Kazantzis & Deane,1998; Koong Hean Foo & Merrick, 2004).
It is derived from cognitive psychology and behaviour therapy in terms of the development of concepts of schema and cognitive belief.
As a consequence of drawing on elements from various therapeutic modalities, cognitive behaviour therapy has nevertheless become quite adaptable to different environments.
For instance, in a search of cognitive behaviour therapy literature from 1967 to 2003, Butler, Chapman, Foreman, & Beck (2006) found 15 methodologically sound meta-analyses covering 9138 participants and 332 studies.
The values inherent in Beck's approach to therapy contained in the term 'Collaborative Empiricism' are also a likely cause of the popular acceptance of cognitive behaviour therapy.
