This study is a qualitative analysis case study on the experiences of violence by domestic violence offenders entrusted with counseling. The purpose of this study was to clarify the factors and identify the experiences of violence of domestic violence offenders based on Bowen's family therapy theory. The subjects of this study were a total of 5 male and female participants who were perpetrators of domestic violence who were sentenced by the D court in K City to entrust counseling for the disposition of domestic protection case No. 8. The study period was from November 2022 to April 2023, with in-depth interviews of 90 minutes per session, and original data such as recording, field notes, and experience reports were analyzed. After confirming the basic information of the research participants and analyzing the original data by categorizing husband violence, wife violence, parental violence, and child violence into 4 categories based on criminal history and domestic violence incident factors, 3 categories and 73 meaning contents were derived. This study attempted to identify the factors of anxiety, self-differentiation, triangular relationships, and family projection processes through qualitative content analysis studies on experiences of violence. The research results are as follows:. First, as the anxiety of domestic violence offenders decreased and violence decreased without emotional reflex behavior, the previously undifferentiated level of self-differentiation improved. Second, there was a positive effect of detriangulating the family triangle of domestic violence perpetrators and forming an autonomous relationship.Third, the effect of stopping violence was found as the multigenerational transfer process was interrupted due to the family projection of domestic violence offenders. Based on these results, positive results emerged where emotional stability and cyclical interaction were observed while confirming immature behaviors in the family of domestic violence perpetrators. These studies suggest that there is the possibility of enhancing the positve effects in future counseling related to domestic violence offenders
