Purpose

The aim of the study was to examine the strength of association between posttraumatic stress disorder (PTSD) as well as alexithymia and dissociation relative to persons, who have experienced one of the following types of trauma: trauma associated with rape or sexual violence (ST), other kinds of trauma associated with being a victim of a fire or an accident (NST).

Method

The total number of participants amounted to 117 women, among whom 39 fell victims to sexual abuse (ST), 39 experienced non-sexual trauma (NST), and 39 denied ever having come through a traumatic situation (NT). Seventy five women (64.1%) admitted that they suffered from PTSD. Three standardised instrument were used to assess alexithymia (TAS-26), dissociation (CES) and Posttraumatic Stress Disorder (PDS).

Results

The ST group is characterised by significantly higher levels of alexithymia, but only in the form of identifying and describing one’s own emotions. The surprising finding was that ST and NT groups reported slightly different levels on the general scale of dissociation, which can be explained by the fact that NST group showed significantly more intensive dissociative tendencies in the form of self-absorption, while ST showed it in the form of depersonalisation and amnesia. In the ST group, significantly more serious PTSD-symptoms were confirmed, particularly regarding the avoidance of stimuli related with trauma. These findings suggest that trauma-type (sexual/non-sexual) might be a key factor determining the extent, kind and intensity of trauma-related disorders.

Conclusions

Dissociation and alexithymia are very important to the development and maintenance of the symptoms of PTSD. The high levels of alexithymia were associated with more serious problems of affective arousal and regulation of affect after trauma.
