本研究檢視性雜亂、敵視女性、暴力接受度與情感同理心對性攻擊及其發生次數的影響。以無記名自陳式問卷在線上蒐集資料，共計有998位居住於台灣的成年男性接受問卷調查。結果顯示有13%的參與者自陳在最近一年內曾從事性攻擊。性雜亂、敵視女性與情感同理心皆可預測性攻擊，但暴力接受度則否。就暴力接受度做進一步分析，發現組成此構念的人際暴力與合法暴力兩成分，各自對性攻擊具有正向與負向關聯，在相互抵銷的效果下，暴力接受度對性攻擊不具預測力。此外，結構方程模型分析顯示，性雜亂、人際暴力、與合法暴力接受度(將暴力接受度的此二成分分開），皆可預測性攻擊的次數。文末就研究結果的意涵、實務應用、研究限制與後續研究方向提出討論。

This study examined the effect of impersonal-promiscuous sex, hostility toward women, acceptance of violence, and affective empathy on occurrence and frequency of sexual assault. Anonymous self-report questionnaire was used to collect data online. A total of 998 adult men participated in the study. The results suggested that the participants who self-reported as having committed sexual assault within the previous year accounted for 13% of the sample. Impersonal-promiscuous sex, hostility toward women, and affective empathy were all predictors of sexual assault occurrence, but acceptance of violence was not. Further analysis of the main components of acceptance of violence revealed that interpersonal violence and sexual assault behavior were positively correlated, whereas legitimate violence was negatively correlated with sexual assault. Because of the combination of positive and negative influences, acceptance of violence was not a predictor of sexual assault. Binary logistic regression analysis indicated that impersonal-promiscuous sex, hostility toward women, interpersonal violence, legitimate violence, and affective empathy were all predictors of sexual assault. Structural equation modeling revealed that impersonal-promiscuous sex, interpersonal violence, and legitimate violence were all predictors of sexual assault frequency. The theoretical implications, practical applications, and research limitations of this study, in addition to future research directions, are discussed.
