The aim of this study was to evaluate dyadic effects among siblings by testing an actor–partner interdependence model of associations between interparental conflict perceptions and children maladjustment. In particular, associations between siblings’ perceptions of interparental conflict properties, threat, and self-blame, and general, personal, school, and social maladjustment and adolescents’ family and sibling dissatisfaction were examined. The hypotheses of the study were analyzed through an Actor-Partner Interdependent Model. The sample was made up of 50 pairs of siblings recruited in Spain; older siblings’ mean age was 13.3 years (SD = 2.51) and younger siblings’ mean age was 10.4 years (SD = 2.33). The results emphasize the association between children’s and adolescents’ perception of interparental conflict and their own maladjustment (actor effect). However, the main novel contribution of this study is the analysis of partner effects for siblings in interparental conflict situations and the results highlight that they are greater for older siblings compared to younger siblings. Also, the results confirm the interdependency of siblings’ perceptions of interparental conflict properties, but also the independency of threat and self-blame feelings experienced by each sibling. Results and limitations of the study are discussed.

本研究的目的是通过测试父母间冲突感知与儿童适应不良之间关联的行为者-伴侣相互依赖模型来评估兄弟姐妹之间的二元效应。特别是，研究了兄弟姐妹对父母间冲突属性、威胁和自责的看法与一般、个人、学校和社会适应不良以及青少年家庭和兄弟姐妹不满之间的关联。该研究的假设是通过演员-合作伙伴相互依赖模型进行分析的。样本由在西班牙招募的 50 对兄弟姐妹组成；哥哥姐姐的平均年龄为 13.3 岁（SD  = 2.51），弟弟妹妹的平均年龄为 10.4 岁（SD = 2.33)。结果强调了儿童和青少年对父母间冲突的感知与他们自身的适应不良（演员效应）之间的关联。然而，这项研究的主要新颖贡献是分析了兄弟姐妹在父母间冲突情况下的合作伙伴效应，结果表明，与年幼的兄弟姐妹相比，兄弟姐妹的合作伙伴效应更大。此外，结果证实了兄弟姐妹对父母间冲突属性的感知的相互依赖性，也证实了每个兄弟姐妹所经历的威胁和自责感的独立性。讨论了研究的结果和局限性。
