The influence of data-driven processing on perceptions of memory quality and intrusive symptoms in children following traumatic events

Ehlers and Clark [(2000). A cognitive model of post-traumatic stress disorder. Behaviour Research and Therapy, 38, 319-345] cognitive model of post-traumatic stress disorder (PTSD) has been relatively untested with children. Seventy-five children (7-16 years) were interviewed within 4 weeks of an injury that led to hospital treatment to examine whether peri-traumatic processing strategies (data-driven processing and fear) were associated with perceptions of memory quality and intrusive memories. Perceptions of memory quality mediated the relationship between data-driven processing and intrusive reactions but not avoidance, arousal or depressive reactions. Finally, the relationship between peri-event fear and intrusion reactions was mediated by perceptions of memory quality even after data-driven processing was controlled. The implications of these findings are discussed in the context of a cognitive developmental model of PTSD in children.
