本研究主要以家庭系統理論學者Bowen所提之「三角關係」概念為理論根據，探討夫妻的婚姻滿意度與其獨生子女涉入父母爭吵的三角關係之關聯性，並比較不同家庭結構、不同性別子女的涉入情形。本研究採用調查研究，選取中部地區有獨生子女的家庭230個樣本為研究對象。本研究依據受試者在「婚姻滿意度量表」以及「父母爭吵時的三角關係運作量表」的得分，進行統計分析。研究結果發現：（1）夫妻婚姻滿意程度愈高，子女愈不會在父母爭吵時涉入三角關係。進一步分析發現，夫妻婚姻滿意程度愈低，子女愈容易在父母爭吵時以「跨世代聯盟」的方式涉入三角關係。（2）父母已離婚之子女比父母未離婚之子女更容易與父母一方聯盟，而父母未離婚之子女則比父母已離婚之子女更容易有親職化的表現。（3）子女在父母爭吵時的涉入情形沒有性別差異。

Based on the theoretical concept of triangulation proposed by Bowen, this study examined the relation betwee marital satisfaction and parent-child triangulation in parents’ marital conflict. Participants included 230 families with only one child. The results revealed that: (1) Marital satisfaction was negatively associated with parent-child triangulation. Among the three dimensions of triangles, the cross-generational coalition was negatively associated with marital satisfaction. (2) Children with divorced parents reported more cross-generational coalition than those with married parents, whereas children with married parents involved more parentification than children from divorced families. (3) There was no significant gender difference in parent-child triangulation.
