Abstract:
Little is known about the usefulness of Case Formulation (CF) to Cognitive Behavioural Therapy (CBT) practice and outcome despite its highly held esteem within Clinical Psychology. The aim of this study was to explore the use of a new approach to formulating, Hallam's (2013) Individual Case Formulation (ICF), as a potential mechanism for contributing to change in PTSD treatment using a single case experimental design (SCED). The study had two components: firstly, training on ICF to shed light on how skills in formulation are developed and secondly, use of ICFs during PTSD treatment of eight individuals. It was hypothesised that ICF workshop training could increase therapist formulation skill. It was also tentatively hypothesised that quality and complexity of ICFs might relate to outcome for people with PTSD and that other specific elements captured within the ICF might link to outcome and rate of improvement for people with PTSD. A secondary hypothesis that sharing a formulation during treatment could be associated with reducing symptoms was also investigated. Formulation diagrams were coded using a newly devised rating scale in order to identify potential elements within ICFs. Coding results from diagrams and patterns of outcome measures from the eight participants were explored at group and individual levels. Due to the small sample size and the observational nature of many of the analyses, results were interpreted with caution. Findings from the training indicated increased formulation quality, suggesting that formulation skill can be enhanced in therapists. Group and individual analysis offered initial, preliminary support for the idea that higher quality CFs might be associated with reduction in symptoms. Other specific items within CFs appeared to show some association with change in symptoms. It was difficult to adequately address the hypothesis regarding complexity, as very little complexity was shown across the sample of diagrams. Initial support was found for the secondary hypothesis, with visual analysis suggesting that some participants demonstrated symptom change following the shared formulation, suggesting that change in symptoms was linked to this process. Potential implications of the findings and suggestions for future research are discussed.
