I found that there are some meanings of gender role duty behind male intimate partner violence (IPV) during my practice. Although there were some related studies, which always explored this issue from the perspective of ”cross-situation” of gender role expectations. This stance is not obligatory as there might be different gender role expectations in different life spaces within the changing Taiwanese society. In order to specify this theme, current research focused on couple role expectations and practices which is known to be a set of beliefs and behaviors within family. This is followed by examining the differences between male IPV and non-IPV. This study adopted constructivism paradigm and recruited 12 wife batterers from the prison and 10 non-IPV males as interviewees. To analyze data, we used open-coding rules of grounded theory and template analysis style. The results can be categorized into five themes: Couple role expectations, Coordination or rigid related to role implementing, Being threatened in male role authority, Dealing with the failure of male role practice, Blaming wife's role practice. Based on these 5 points of view, the interviewed results appear that couple role practice has more meaning within the male intimate partner violence in the current study.
