Intrusive images are a common phenomenon in post-traumatic stress disorder (PTSD; American Psychological Society, 2013). Imagery-Rescripting (ImRs; Arntz & Weertman, 1999) is an experiential technique for targeting intrusive images and is gaining popularity as a treatment for PTSD (Arntz, 2012). Although there is evidence to suggest that ImRs is an effective treatment of PTSD (see Arntz, 2012), it is currently unclear how ImRs works. The aims of the present study were 1) to develop a coding scheme that captured important factors of ImRs session, and 2) to apply this coding scheme prospectively to investigate how certain factors might relate to treatment outcome. The study used thematic analysis (Braun & Clarke, 2006) to develop an ImRs coding scheme. Next, a single case experimental design was employed to track six participants over the course of their ImRs therapy for PTSD. Session content captured by the coding scheme was compared to changes in weekly outcome measures to investigate whether the presence of certain codes related to a reduction in PTSD symptoms. Results suggested a number of factors might be important for determining treatment outcome. Specifically, Attitude towards ImRs, Activation of the image, Ability to follow ImRs, Activation of original internal processes and internal processes during the re-script, Believability and Attitude towards the outcome are suggested as potentially important factors for determining ImRs efficacy. Study strengths, limitations and clinical implications are discussed. Recommendations for future research, including in-depth investigation of individual factors are suggested.
