本研究旨於探討台中市四親等內旁系血親、旁系姻親之家庭暴力現象，以個 案資料內容分析為主，輔以社工人員焦點團體訪談，主要分析其暴力態樣、受暴 頻率、兩造關係、人口特徵、受暴及發生原因等面向。研究發現，此類案件呈現 嚴重程度低、頻率低、求助意願低等現象；兩造關係以兄弟姊妹為多數，暴力衝 突原因多元，但大致以長輩照顧、財產紛爭、生活磨擦等議題佔多數，且衝突原 因多乘載了家族內長期的情緒與資源衝突。本研究分析之個案資料，多以警政通 報系統、社工隨後介入為主，但實務上求助者對問題解決的期待與受助意願偏低。 此類被害人為男性之比例明顯偏高；外籍配偶面臨的四親等內家暴議題則有其特 定脈絡。

This study aims to explore the phenomenon of non-IPV(intimate partner violence) domestic violence between family members in Taichung city. Methods of content analysis of casework records as well as Focus Group Interview are used as data collection. Types and frequencies of violence, relationships between two sides, demographic characteristics of the victims, and causes of violence are discussed. The main findings include, firstly, violence between siblings appears lower degree of severity, lower frequency, and lower willingness to seek help, compared to IPV population. Secondly, violence between siblings constitutes a great portion of the cases. Thirdly, the causes of violent conflict are diverse, mainly related to issues of elders care, property disputes, and daily life friction. However, those who reported to be victims seem to have lower expectations and willingness to work with formal systems. It concludes that the nature of non-IVP domestic violence between family members is distinct from typical IPV in terms of its patterns of violence and desired solutions. Specially, the violence issues involved married immigrant women need to be contextualized and investigated in details.
