目的：本研究乃以資源流失、控制、無望、憂鬱及自殺危險程度當為引發自殺行為或增加自殺危險性的因子，來說明這些變項中何者最能預測自殺企圖者與對照組的差異。 方法：本研究採用配對個案控制設計，配對自殺企圖組與對照組具有相同的性別、年齡及居住地區。如此的配對共收集了129對，之後比較這兩組受試在資源流失、控制調節策略、無望、憂鬱及自殺危險程度的差異。所採用的工具分別為資源流失調查表、控制調節問卷、無望感量表、貝氏憂鬱量表、自殺危險程度量表。 結果：自殺企圖組顯著地比對照組有較多的資源流失、較高的無望、憂鬱及自殺危險性，而且採用較多的逃避及較低的初級與次級控制。在洛基迴歸分析的結果中顯示，最能區分這兩組的變項，依序為自殺危險性、逃避、個人資源流失、控制及降低抱負水準。 結論：本研究的結果支持過去研究所發現的「自殺企圖是預測未來會自殺的良好變項」的看法，而建議自殺防治工作需著重於自殺企圖者的偵測與早期介入高危險偵測的看法。

Objective: The present study investigated the impact of resource loss, control strategy, hopelessness, depression, and suicide risk on suicide attempt. Method: Using a case-mathed design matched for gender, age and living location, 129 pairs of subjects were recruited and assigned into the suicide attempt and control groups. Each subject was assessed by “Resources Loss Inventory”, “Control Inventory”, “Hopelessness scale”, “Beck Depression Scale” and “Suicidal Risk Inventory”. Results: The results demonstrated that suicidal attempters significantly experienced more resources loss, hopelessness, depression, and suicidal risk than the control group. Also, suicidal attempters used more escape strategies and less primary and secondary control strategies. From the results of logistic regression, the suicidal risk is the best predictor that differentiated these two groups. Other predictors included escape, personal resource loss, control, reduced aspirations. Conclusion: Consistent with previous findings, the current data indicate that it is improtant to detect the high suicidal risk population and intervene in order to prevent suicidal behavior.
