研究背景與目的：
再犯預防模式是現行最常用來治療性侵害加害人的處遇，其理念基礎源自於社會學習理論，因此結果預期與效能預期是再犯預防中重要的概念，然而性侵害加害人處遇實務工作中，缺少能有效評估性侵害加害人之強暴行為結果預期、拒犯強暴行為自我效能量表，也缺少驗證強暴行為結果預期是否能透過拒犯強暴行為自我效能預期之中介而預測強暴行為發生之實徵資料。
是故，本研究編製強暴行為正向結果預期、強暴行為負向結果預期與拒犯強暴行為自我效能等三量表，以性侵犯為主要研究對象，並取毒品犯與正常組為兩組對照組，比較性侵犯組、毒品犯組與正常組在強暴行為正向結果預期、強暴行為負向結果預期與拒犯強暴行為自我效能之差異，並進一步驗證強暴行為結果預期是否能透過拒犯強暴行為自我效能預期之中介而預測強暴行為之發生。
研究方法：
參與者，50名性侵犯、100名非性侵者（毒品犯與正常組各50名），共計150名。參與者需同意參與本研究，年齡介於18至65歲之男性；另外，需排除智能不足、不識字者、具有精神病症狀及其他嚴重的精神病需住院治療或危機處置者。
研究工具，個人資料表、自編強暴行為結果預期量表與自編拒犯強暴行為自我效能量表。
研究程序，研究者向符合取樣標準之參與者說明本計劃內容與目的後，若參與者同意則簽署同意書；經同意之參與者填寫個人資料表、強暴行為結果預期量表與拒犯強暴行為自我效能量表，並獲得禮品乙份。最後進行資料分析。
資料分析，以分析性統計、卡方與F檢定、相關分析，以及階層迴歸分析等方式，對研究假設進行分析與驗證。
研究結果：
本研究之結果（1）性侵犯組、毒品犯組與正常組在強暴行為正向結果預期分數上未達顯著差異；（2）性侵犯組與毒品犯組在強暴行為負向結果預期分數上未達顯著差異，但二組均明顯低於正常組；（3）性侵犯組在拒犯強暴行為自我效能分數上明顯低於毒品犯組與正常組；（4）對強暴行為的低負向結果預期會透過低拒犯自我效能之部分中介而預測強暴行為的發生。
結論：
本研究編製的強暴行為正向結果預期量表具有良好信度，但其效度有待進一步驗證。強暴行為負向結果預期量表與拒犯強暴行為自我效能量表，除信度良好之外，可用來評估個體對強暴行為的負向結果的預期程度，以及個體拒犯強暴行為的信心程度，亦可運用在性侵害加害人處遇實務工作中，做為預測個體是否會做強暴行為的參考指標之一，也能當作是處遇介入前後效果的衡鑑工具。

There were three purposes in the present study. First three scales, including the Rape Positive Outcome Expectancy Scale, Rape Negative Outcome Expectancy Scale, and Refusal Self-Efficacy of Sexual Offending Behaviors Scale, were developed and their psychometric properties were analyzed. Second, the differences of rape positive/ negative outcome expectancy and refusal self-efficacy of sexual offending behaviors were examined among rapists, drug offenders and a normal control group. Third, it was tested whether refusal self-efficacy mediated the relationships between outcome expectancy and sexual offending behaviors. The participants consisted of three groups, including 50 rapists, 50 non-rapist drug offenders and 50 normal controls. Results showed (1) there was no significant difference in rape positive outcome expectancy among the three groups; (2) both rapists and drug offenders revealed less rape negative outcome expectancy than the normal controls, but there was no significant difference between rapists and drug offenders; (3) rapists showed the lower levels of refusal self-efficacy for sexual offending behaviors than drug offenders and the normal controls; (4) refusal self-efficacy of sexual offending behaviors partially mediated the association of rape negative outcome expectancy with sexual offending behaviors. The treatment and assessment were discussed in light of these findings.
