Facial Expression and Experience of Emotions in Psychodynamic Interviews with Patients with PTSD in Comparison to Healthy Subjects

Background: The facial affective behavior of traumatized patients and of a healthy control group was compared. Sampling and Methods: Data of 15 videotaped clinical interviews of traumatized inpatients and of 15 healthy women (absence of mental/psychiatric disorder according to ICD-10) were ascertained. The affective facial expression of both groups was coded with the Emotional Facial Acting Coding System. Afterwards, the mimic analysis was correlated with gazing behavior and the emotional experience. The patients reported their traumatic experiences and the healthy women their main complaints. Results: The traumatized patients showed neither a reduction of overall facial expressions nor a reduced frequency of facial affects in comparison to the healthy control group. The control group, however, showed significantly more ‘genuine joy’. The traumatized patients showed significantly more anger. Conclusions: The traumatized patients did not show a significant reduction of overall facial expression. A more detailed analysis showed that on the one hand, stabilizing elements of relationships, such as genuine joy, appear significantly less on the face of traumatized patients as compared with the healthy women. On the other hand, the expression of anger was brought into the relationship significantly more often by the traumatized patients during face-to-face interaction (clinical interview). This indicates the importance of distance regulation interaction patterns of traumatized patients.
