Abstract
Posttraumatic Stress Disorder (PTSD) is a severe mental disorder characterized by distressing intrusions. Since not all traumatized individuals develop PTSD, it is important to understand its underlying risk factors. So far, several psychological and physiological risk factors have been identified. However, these factors have rarely been examined together. An excellent tool to assess analogue PTSD in a prospective manner is the trauma film paradigm. This study examined relevant psychological and physiological factors in 60 healthy participants before, during and after the presentation of an ”traumatic” film clip, including rumination, dissociation, anxiety, mood, cortisol and psychophysiology measures. Moreover, we assessed intrusions and administered the Impact of Event Scale – Revised for one week following the “trauma”. While none of the physiological variables was predictive, state rumination together with state anxiety and trait dissociation predicted analogue PTSD symptoms in slightly different patterns. Practical implications are discussed with regard to PTSD.
