This research report documents the therapeutic intervention undertaken with a 23-year-old Swazi rape victim. The format of this research report takes the form of a case study that follows the principles proposed by Fishman (2005). Its aim is to document the treatment process of an individual of African decent in order to establish whether the treatment model can be effective in clinical settings and in contexts and cultural settings different from that in which it was developed. The Ehlers and Clark (2000) cognitive therapy model for post-traumatic stress disorder (PTSD) was utilised to assess, conceptualise, and treat the case. The client entered therapy three years after being raped for a third time. The case formulation identified factors maintaining the disorder as well as how other traumatic and abusive events earlier in her life influenced her response to the rapes. Data consisted off audio-tape recordings and detailed written synopses of each assessment and therapy session, psychometric measurement instruments and self-report scales completed throughout the intervention, material written by the client, and a research interview conducted by an independent party. She was treated for PTSD and comorbid depression over a period of five months in accordance with the principles described by Ehlers and Clark and a narrative of the treatment process was written. The case narrative in conjunction with quantitative data suggested that this model assisted the client in initiating a healing process. As such the model was found to be both effective and transportable to an African context. Various points of discussion are highlighted, including the challenges of working with PTSD and comorbid major depression, the client-therapist relationship, and that a client and therapist from different cultures, backgrounds, and with different home languages can work together effectively using the Ehlers and Clark model.
