從角色默契消失到敵意湧現的惡化歷程：認定伴侶不貞的男性親密殺人心理探究

The Deterioration Process Resulting from the Loss of Role Understanding to the Emergence of Hostility: Intimate Partner Homicide Caused by Accusations of Infidelity

不貞是親密殺人的重要前導事件，國外雖已累積不少研究，但多數缺乏文化考量；國內雖已開啟殺害不貞伴侶之心理探究、且融入華人文化的考量，但皆為單一受訪者的敘事探究；故國內外文獻皆有闕漏。為了周延建構台灣此類殺害伴侶者的心理機制，本研究從華人關係主義的角度切入，邀請十位認定伴侶不貞的男性親密殺人者進行深度訪談，並審閱其判決書、社工紀錄、犯罪紀錄，再以共識質性研究法分析文本。研究結果彙整出一個特徵範疇與四個歷程範疇，前者為「思維：關係主義的男性貞節信念」，後者包括「遠因：角色默契消逝的伴侶衝突」、「近因：信任崩解後的敵意湧現」、「爆發：親密暴行質變、憤恨殺害伴侶」、「回首：後悔」。此歷程結果有兩個可能的意涵：其一，從關係主義的觀點來審視，受訪者親密殺人歷程似是一個「從角色默契消失到敵意湧現的惡化歷程」；其二，認定伴侶不貞後出現的信任崩解／敵意湧現，可能是受訪者從相對輕微的親密暴力、惡化變質成殺害伴侶的促發因子之一－但此推測未曾見於先前文獻，後續研究可進一步探討。

Accusing one’s partner of infidelity is one of the major causes stated by offenders when intimate partner homicide occurs. Much research has been undertaken concerning this issue among western research literature， but most of them lacked cultural considerations with respect to the psychological process of homicide. In Taiwan， researchers who investigated this topic with Chinese cultural consideration undertook only narrative research based on a single participant， which only presented the specific experience from an individual’s perspective and thus generalization is limited. Therefore， there is a gap within the literature on this this topic area. This study is based on Chinese Relationalism perspectives and is designed to comprehensively construct the psychological mechanism behind this type of homicide. Participants of this study consisted of ten male prisoners who accused their partners of infidelity and were convicted of homicide. Consensual qualitative research (CQR) was applied to analyze interview scripts， along with consulting written verdicts， criminal records， and records maintained by social workers. The results revealed one characteristics category and four process categories. The former was “Personal thoughts: Male thinking related to fidelity based on Chinese Relationalism”. The later includes (a) Fundamental reasons: couple conflicts along with the loss of role understanding; (b); Proximate reasons: the emergence of hostility after losing trust; (c) Explosion: the worsening of intimate partner violence and accumulated rage leading to intimate homicide. (d) Looking back: regret. There were several implications from these results. Firstly， based on Chinese Relationalism， the interviewees’ homicide process seemed to be “a deterioration process resulting from the loss of role understanding to the emergence of hostility.” Secondly， based on the results， it could be hypothesized that “during the process of intimate partner homicide， the loss of trust and the emergence of hostility caused by partner infidelity might be an important reason for the worsening of intimate partner violence.” However， no research literature has discussed the role of the trust/hostile related to the intimate partner homicide caused by accusation of infidelity; thus， this would be an important area for future research to explore.
