D.Litt. et Phil. / A plethora of research has been conducted on victims of township violence, detention and political unrest, but there is no research on car hijack victims or the prevalence of Post-Traumatic Stress Disorder (PTSD), which could result from this crime. The implications of this lack of research are important because people are confronted by trauma on a daily basis but there are few guidelines for providing treatment. Hijackings are a somewhat recent phenomenon unlike other traumas such as wars and natural disasters, but the effects of hijacking are no less severe. Post-Traumatic Stress Disorder (PTSD) always requires an initiating event which is assumed to be traumatic. The context in which car hijackings occur in South Africa can be considered to meet the criteria for what constitutes a traumatic event, which could possibly lead to the development of PTSD (Myerson, 1995). Not all crime victims who need professional assistance will enter therapy. This is often due to the victim's self-perception of weakness, feelings of embarrassment, or the perception that others will not understand their experience. A group-based intervention offers the advantages of reducing isolation, providing comfort and support, and eliminating feelings of stigma. For this reason it was important to analyse the nature of PTSD and how to intervene to aid the recovery from PTSD, in the South African context. The literature points to the recovery from PTSD as being contingent upon the psychotherapeutic input that the traumatised individual receives. This research focused on the development of a group-based cognitive behaviour intervention programme for victims who developed Post-Traumatic Stress Disorder as a result of car hijackings. Cognitive behavioural therapy is the only treatment modality that is supported by objective measures of success (Peterson, Prout & Schwartz, 1991) and has been found to be one of the most effective treatments (Kaplan & Sadock, 1993). In order to test the hypotheses, the Beck's Depression Inventory was used to measure the level of depression, the Spielburger's Stai Anxiety scale was used to measure the level of anxiety, and the CAPS and PCL were used to determine whether Post-Traumatic Stress Disorder existed in the individuals who participated in the study and the intensity and frequency of the symptoms.
