Abstract

Part One of the thesis is a literature review of the effectiveness of Imagery Rescripting as a therapeutic technique for posttraumatic stress disorder. The study updates and expands upon previous reviews. It reviews 17 studies and suggests that Imagery Rescripting is effective in reducing symptoms of posttraumatic stress disorder. Further, higher-quality research is needed to understand the underlying mechanisms of Imagery Rescripting and potential differences between existing Imagery Rescripting protocols. Part Two presents the findings from a feasibility trial of a novel Imagery Rescripting intervention for Somatic Flashbacks in posttraumatic stress disorder. The intervention was found to be feasible, safe, and acceptable. Following the intervention, participants experienced a significant reduction in the frequency of their somatic flashbacks, and participants their sense of coping with them flashbacks improved significantly. Areas of development include better understanding the prevalence of somatic flashbacks, the mechanisms underlying Imagery Rescripting, and the optimal content and timing of an Imagery Rescripting intervention. Part Three is a critical appraisal and reflection on the research process. It focuses on the experience of completing the empirical study at the same time as the literature review. It also offers reflections on carrying out a feasibility study within the National Health Service and discusses dilemmas that arose during the project.
