Sibling relational aggression is an understudied social and family process that is of developmental significance in adolescence, a period of interpersonal relationship development. This study examined developmental change in sibling relational aggression across adolescence and used multilevel actor-partner independence models to test its longitudinal associations with mother-adolescent, father-adolescent, and sibling relationship qualities. Participants were 196 adolescent (firstborn-secondborn) sibling pairs from predominantly White families who averaged 16.47 years ( = .80) and 13.88 years ( = 1.15) of age, respectively, at baseline. Data were collected separately from each sibling during home interviews at three timepoints, each spaced a year apart. Longitudinal growth modeling revealed declines in sibling relational aggression from early to late adolescence. Findings from longitudinal multilevel actor-partner independence models revealed a negative within-person (WP) effect of father-adolescent intimacy and a positive WP effect of father-adolescent conflict on sibling relational aggression: On occasions when adolescents reported lower intimacy or more conflict with their fathers than usual (compared to individuals' own cross-time averages), adolescents reported experiencing more sibling relational aggression than usual. A between-person (BP) effect of mother-adolescent conflict also indicated that the cross-time average of mother-adolescent conflict was linked positively to the cross-time average of sibling relationship aggression. Primarily at the WP level, associations also emerged between lower sibling intimacy and higher sibling conflict and sibling relational aggression. For relationships with fathers and siblings, some effects were moderated by sibling structural characteristics. Discussion highlights the interplay of family relationship dynamics, including gender dynamics, and sibling relational aggression in adolescence.

同胞关系侵犯是一个研究不足的社会和家庭过程，在青少年时期具有发展意义，这是人际关系发展的一个时期。本研究考察了青少年时期同胞关系侵犯的发展变化，并使用多层次演员-伙伴独立性模型来检验其与母子、父子和兄弟姐妹关系质量的纵向关联。参与者是来自以白人为主的家庭的 196 对青少年（长子-次子）兄弟姐妹，他们的平均年龄分别为 16.47 岁（ =.80）和 13.88 岁（ = 1.15），基线时分别为 16.47 岁（ =.80）和 13.88 岁（ = 1.15）。数据分别从每个兄弟姐妹在家访期间的三个时间点收集，每个时间点相隔一年。纵向增长模型显示，同胞关系侵犯从青少年早期到晚期呈下降趋势。纵向多层次演员-伙伴独立性模型的结果显示，父亲与青少年的亲密关系的个体内（WP）负效应和父亲与青少年的冲突的 WP 正效应与同胞关系侵犯有关：当青少年报告与父亲的亲密关系低于通常水平或与父亲的冲突比通常水平更多时（与个人自己的跨时间平均值相比），他们报告的同胞关系侵犯比通常水平更多。母子冲突的个体间（BP）效应也表明，母子冲突的跨时间平均值与兄弟姐妹关系侵犯的跨时间平均值呈正相关。主要在 WP 水平上，兄弟姐妹关系的亲密程度较低和冲突程度较高与兄弟姐妹关系侵犯之间也存在关联。对于与父母和兄弟姐妹的关系，一些效应受到兄弟姐妹结构特征的调节。讨论强调了家庭关系动态，包括性别动态，以及青少年时期兄弟姐妹关系侵犯之间的相互作用。（PsycInfo 数据库记录（c）2024 APA，保留所有权利）。
