Abstract

In this article, we review research supporting the modified Stroop color-naming paradigm as a means for assessing intrusive cognition in patients with post-traumatic stress disorder (PTSD). Because Stroop interference reflects involuntary semantic activation, delayed color-naming of trauma-related words can provide an objective index of intrusive cognition that is not based on self-report. In a replication and extension of previous research, we found that Vietnam combat veterans with PTSD exhibited Stroop interference for trauma-related words but not for other threat words, positive words, or neutral words. Also, we provide reliability and validity data on the paradigm.
