Imagery Rescripting Therapy: identifying factors associated with successful outcome in PTSD

Abstract

Imagery rescripting (ImRs) is a psychological intervention effective in treating intrusive images in PTSD. Studies have suggested factors in ImRs which may influence outcome; however, research is still in its infancy, with mechanisms of action still unknown and factors which make it successful unclear (Arntz, 2012). This study aimed to investigate therapists’ experience of the process of delivering ImRs in PTSD and what they believe make it an effective intervention. The study used a Grounded Theory (GT) approach to investigate eight therapists’ experience of using ImRs in PTSD, and their view of what makes it successful. A GT analysis produced a model illustrating the process of using ImRs, consisting of four theoretical themes: using ImRs in PTSD, facing obstacles in working with the imagination, identifying the mechanisms of action and moving from the unknown to the known. The main suggested mechanisms of action involved re-establishing power and enabling an emotional shift to occur. The model highlighted inter-relationships existing, with distinct themes feeding into each other. The GT model suggested more structure and research is required for an increased understanding in ImRs, allowing therapists to feel more confident and comfortable using the perceived anxiety-provoking technique. Future research could focus on interesting findings from this study allowing an already powerful therapeutic tool to develop and become a more widely-used and prioritised treatment technique in PTSD.
