本研究主要採用資源保存理論的壓力模式來檢驗921地震發生兩年半後，災區居民的資源流失與因應行為對身心症狀的影響，並比較不同社區組織與族群在資源流失、因應行為及身心症狀上的差異本研究主要採用問卷調查法，研究對象為南投埔里鎮居民，有效樣本共354份。受測樣本的設計分為目前住在組合屋和目前住在自己家中以及原住民和非原住民。研究工具包括「創傷後壓力反應指標問卷」、「資源流失調查表」及「因應量表」。資料的處理以相關分析、路徑分析、階層回歸分析和單因子共變數分析為主。本研究結果發現如下：（1）資源流失與逃避式的因應均能預測災區居民的身心症狀，但資源流失對身心症狀的預測要大於逃避式因應，且在四種類型的資源中，以個人資源流失的預測力最強。（2）在不同社區組織的比較中，組合屋居民出現較多身心症狀和資源的流失，且個人資源的流失和逃避式因應均是預測其身心症狀的最強變項。（2）在不同族群的比較中，原住民族群與非原住民族群在身心症狀和資源流失上沒有明顯差異，但原住民族群報告較多逃避式的因應，且逃避式的因應是預測其身心症狀的最強變項。根據研究結果，本研究對地震後的復建提出以下幾點建議：（1）減緩災難後資源的流失並增加資源的獲得。（2）社區組織的介入。（3）增強原住民族群的因應行為。 關鍵字：921地震、資源流失、因應行為、組合屋、原住民 / This study used the Conservation of Resources stress model to examine the effects of resources loss and coping behavior on psychological/physical symptoms after the 921 earthquake. And compared with the differences of resources loss, coping behavior and psychological/physical symptoms in different community organizations and races. This study was conducted by questionnaire investigation. 354 participants living in Pu-Li Town completed the questionnaires. The design of samples was distinguished between living in Temporal houses and living in own houses, and aborigines and non-aborigines. The measurements applied in this study included "Posttraumatic Stress Reaction Index Questionnaire", "Resources Loss Inventory" and "Coping Scale". The obtained data was analyzed by Pearson product-moment correlation, path analysis, hierarchical multiple regression analysis and one-way ANCOVA. The results of this study included: (1) resources loss and avoidant coping could predict psychological/physical symptoms, but resource loss predicted psychological symptoms better than avoidant coping. Personal resources were the strongest predictor among four kinds of resources. (2) In different community organizations. Temporal house's residents reported more resources loss and psychological/physical symptoms. And personal resources and avoidant coping were the strongest predictors. (3) In different races, the level of resources loss and psychological/physical symptoms were no significant differences between aborigines and non-aborigines. But aborigines revealed more avoidant coping and avoidant coping was the strongest predictor. Based on the results, some suggestions to post-earthquake rehabilitation were included: (1) Acting to limit resources loss after disaster and increase resources gain. (2) Considering the intervention of community organization. (3) Enhancing aborigine's coping behavior. Keywords: 921 earthquake, resource loss, coping behavior. Temporal houses, aborigines
