We applied a prospective design to reinvestigate the issue whether the sub-domains of alexithymia could be considered stable traits or distress-related states. Assessments of alexithymia and subjective distress were conducted before deployment to Kosovo in a sample of male peacekeepers. A second assessment was conducted approximately six months later during the final phase of service. The results showed evidence of moderate to high relative stability in all alexithymic sub-domains. It was also found that a relative change in subjective distress predicted a relative change in difficulty identifying feelings and difficulty describing feelings but not in externally oriented thinking. We suggest therefore that the alexithymic sub-domains could be considered relatively stable traits but that the level of difficulty identifying and describing feeling varies with the level of subjective distress.

In this study a prospective design was used to investigate the interaction between baseline trait anxiety and exposure to traumatic situations on post-trauma symptoms of anxiety and insomnia in a sample of Swedish peacekeeping soldiers serving in Kosovo. The result showed that pre-trauma trait anxiety interacted with exposure to traumatic situations predicting a higher post-trauma distress. Further, baseline trait anxiety and baseline symptoms of anxiety and insomnia predicted post-trauma symptoms of anxiety and insomnia. The results support a diathesis stress model in which high trait anxiety interacts with trauma exposure in the elicitation of anxiety-related distress but the study needs to be replicated before further conclusions can be drawn.
