The findings from three papers represent a detailed analysis of the therapist–client dyads using theme-orientated discourse analysis (Roberts & Sarangi, 2005; Sarangi, 2010). A form of psychotherapy that evolved from the separate but related traditions of behavioural therapy and cognitive therapy, CBT is a major form of psychotherapy recommended by a number of professional bodies and evidence-based treatment protocols for the treatment of a range of psychiatric disorders. There is a wealth of quantitative research attesting to the efficacy of CBT through randomised controlled trials; however, little is understood about how the treatment model of CBT, that is, the underlying theory and related techniques that inform the therapy, is put into practice in everyday clinical settings. In this thesis three crucial aspects of the treatment model are investigated. They are: negotiating the problem statement, homework-setting and termination (ending) of therapy. The analysis makes use of Candlin's concept of crucial sites and critical moments (Candlin, 2000) to focus on relevant parts of the transcript for further analysis. Theme-orientated DA is used as the method of analysis as it is specifically designed for health-related interactions and to connect professional concerns to the discourse analysis. In this case it enables connections to be drawn between aspects of the treatment model of CBT and discursive processes employed by the participants.cognitive behavioural therapy; discourse analysis; theme-orientated discourse analysis; psychotherapyThesis20140813104833
