1999年台灣921芮氏7.3級集集大地震，全國各地均有災情傳出，在台北縣又以新莊地區受創最為嚴重，A博士的家B、A龍閣B兩棟社區大樓均在強震中倒塌，災民受創嚴重，故瞭解災民創傷後心理反應及其影響因素是當前重要之課題。本研究為橫斷式調查法，採立意取樣，以北縣新莊地區80位受災民眾為研究對象，研究結果顯示：災民創傷後反應以「我常不自主的就會想到地震這件事」出現頻率最高，「對地震這件事我感覺麻木」出現頻率最低。有超過一半的民眾(55%)壓力反應得分超過19分，顯示災民於地震七週後仍普遍感受到地震所帶來的壓力。而在影響災民震後創傷反應之相關因素則為：職業狀況、家庭月收入、自覺工作是否有影響。研究結果可幫助護理人員早期辨識災民創傷後反應，有效參與災後心理重建工作，並提供政府相關部門政策擬定與災變後續追蹤之依據。

　　　　　In 1999, the Chi-Chi earthquake in Taiwan caused severe damage. Hsinchuang City in Taipei County was one of the areas seriously damaged. Two residential buildings collapsed and many victims were badly hurt. Accordingly, the most important issue after this disaster was to understand the post-traumatic responses of 9-21 earthquake victims and related factors. The purpose of this cross-sectional study was to explore the post-traumatic responses of earthquake victims and related factors. With purposive sampling, a questionnaire was used to collect data from 80 victims from Hsinchuang, Taipei County. The most frequently seen post-traumatic response in this study was “I thought about it when I didn't mean to” and the least frequent was “My feelings about it were kind of numb” Fifty five percent of victims still displayed severe post-traumatic responses during the seventh week after the earthquake. Factors related to the development of these post-traumatic respon-ses were occupation, family income, and perception of work being influenced. The results of this study could help nurses to identify post-traumatic responses at an early stage and efficiently work out victims' mental rehabilitation. They could also serve as a reference for the government to facilitate the rehabilitation process for victims.
