신체형 및 심리형 해리와 과각성이 외상 후 스트레스 증상에 미치는 영향: 예비연구 = The Effects of Somatoform and, Psychoform Dissociation and Hyperarousal on Posttraumatic Stress Symptoms: A Pilot Study

다국어 초록 (Multilingual Abstract)

The purpose of the present study was to examine the effects of somatoform and, psychoform dissociation and hyperarousal on posttraumatic stress symptoms. We also investigated the differences between the two groups in heart rate variability (HRV) under different conditions.
The experimental group included 14 individuals who had experienced traumatic events within 3 months. The control group included 14 healthy individuals who were matched for gender and age to the experimental group. All participants were asked to complete a series of self-report questionnaires pre- and post-treatment. Their heart rate variability (HRV) was recorded at baseline, recall, and during the recovery periods (for 5 minutes in each period).
The results showed that experimental group reported lower heart rate variability at baseline than the control group. Furthermore, the hierarchical regression analysis indicated that only somatic dissociation contributed significantly to the prediction of posttraumatic stress symptoms among the prediction factors of the present study. Finally, the clinical implications and several limitations of the present study were discussed.

국문 초록 (Abstract)

본 연구에서는 신체형 및 심리형 해리와 과각성이 외상 후 스트레스 증상에 미치는 영향력에 대해 살펴보았다. 또한, 실험군과 통제군이 심박변이도(heart rate variability; HRV)의 개별적인 조건 하에서 어떠한 차이를 나타내는지를 검토하였다. 참여자들은 외상사건을 경험한지 3개월 이내인 급성단계의 실험군 14명과 성별과 연령대에 따라 짝진 건강한 통제군 14명이었다. 각 참여자들은 처치 전후에 일련의 자기보고식 질문지를 완성하였다. HRV는 기저선, 회상기 및 회복기에걸쳐 각 5분씩 측정하였다. 실험결과, 기저선에서 실험군은 통제군보다 HRV가 더욱 낮게 활성화되는 양상을 보였다. 게다가, 위계적 회귀분석에서는 본 연구의 예측변인 중 신체형 해리가 외상후 스트레스 증상을 예측하는데 있어 유의하게 기여하는 것으로 나타났다. 마지막으로 본 연구의의의와 제한점, 후속 연구를 위한 제언을 논의하였다.
