The role of pre-existing assumptions and cognitive flexibility in the development of post-trauma cognitive processes - an analogue study.

Objective: This experimental study investigated whether the trait factors of world assumptions and cognitive flexibility were predictive of levels of attentional bias to threat stimuli, memory integration, and data-driven processing.

Methods: An opportunity sample of 74 participants took part in the investigation. Participants viewed a virtual reality film to induce mild distress to mimic processes that can occur in individuals when experiencing a traumatic event. A prospective experimental design was conducted involving measurements at pre-trauma exposure (Time 1), post-exposure (Time 2) and one-week follow-up (Time 3). Self-report measures of world assumptions, cognitive flexibility, and cognitive processing were administered. Eye-tracking equipment was used to assess attentional bias towards threat images, and a free recall task to assess memory integration.

Results: A mixed effects linear model found increased cognitive bias towards trauma-related threat images pre/post-exposure, specifically for a maintenance attentional bias. Significantly greater data-driven processing was observed post-exposure, with greater conceptually driven processing observed at one-week follow-up. No significant findings were observed for memory integration. World assumptions were predictive of increased data-driven processing; the relative use of data-driven to conceptually driven processing; and trait anxiety. Cognitive flexibility was predictive of state anxiety.

Conclusion: These results provide additional support for the role of maintained attention, data-driven processing, and conceptually driven processing in post-trauma reactions as per established cognitive theories of post-traumatic stress disorder. More research is required to fully explore the roles of core beliefs, assumptions and cognitive flexibility in this area.
