title: Processing threatening information in posttraumatic stress disorder.
abstract: The authors used a modified Stroop task to study how people with posttraumatic stress disorder (PTSD) process threatening information. Participants were motor vehicle accident (MVA) survivors with either PTSD (n = 15), simple phobia of driving (n = 15), or low anxiety (n = 15). Participants named colors of 4 types of words: strong threat words (MVA related), mild threat words (MVA related), positive words, and neutral words. Participants with PTSD demonstrated greater interference on strong threat words than those with simple phobia or low anxiety. Contrary to expectation, participants with simple phobia did not display an interference effect. Findings suggest that individuals with PTSD and simple phobia may process threatening information differently. The nature of attentional bias in different anxiety conditions following trauma is discussed.
