The congruence between facial expressivity and self-report of emotion was examined among 11 women with sexual assault-related PTSD and 8 women without PTSD, under both a neutral and a sexual assault prime condition. The PTSD group demonstrated some incongruities in emotional responding. Although the PTSD group was as facially expressive as the control group, they reported more arousal to the emotional stimuli. Further, an inverse relationship between negative facial expressivity and self-report to negative stimuli was found for some variables for the PTSD group only, such that the less expressions they showed facially, the more negative they reported feeling. However, the overall pattern of results suggests fewer significant relationships between expression and experience than predicted.
