Abstract
Worldwide 70% of people experience a traumatic event, with some developing post-traumatic stress disorder (PTSD), mainly characterized by intrusive memories. The development and persistence of intrusive memories may be related to an individual’s emotional state, while resilience may serve as a potential variable in facilitating recovery from such memories. In this thesis a relationship between an elevated emotional state and a higher number of intrusive memories after watching a traumatic film is hypothesised. Furthermore, it is expected that this relationship will be moderated by resilience. Study participants are undergraduate psychology students (n=147). The study follows an experimental design, including a trauma film to induce intrusions. The trauma film serves as an analogue for PTSD by showing participants films containing traumatic content, such as scenes of blood, interpersonal violence, and death, that are consistent with events listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM). Intrusive memories were measured through a prospective intrusion diary and retrospective intrusion ratings. Emotional state was assessed with a pre- and post-film Visual Analogue Scale (VAS). Resilience was measured using the Connor-Davidson Resilience scale (CD-RISC 25). Results were analysed using hierarchical multiple negative binomial- and linear regression analysis. The findings of this thesis demonstrate a significant increase in emotional state of participants following exposure to a traumatic film. As expected, emotional state positively predicted the occurrence of intrusions, both in the prospective diary and the retrospective intrusion ratings. However, resilience did not have a significant moderating effect on these relationships. In the regression models that incorporated the moderation analysis, emotional reaction lost significance as a predictor of image-based diary intrusions but remained a significant predictor of retrospectively assessed intrusions. Regarding future research, is suggested that future studies researching intrusions use appropriate statistical methods to accommodate their data to draw more valid and reliable results.
