研究表明，兄弟姐妹之间的联系对于理解青少年的问题行为很重要。使用一种新的行为遗传设计，目前的研究调查了300个儿童对（7-13岁）的同伴网络重叠，分为5种二分体类型：同卵双胞胎（MZ），异卵双胞胎，全兄弟姐妹（FS），朋友对和虚拟双胞胎（即，年龄相同，基因无关的兄弟姐妹）。遗传相关性，性别组成和年龄差异有助于兄弟姐妹二人组中的同伴重叠。MZ双胞胎显示出最高的重叠（82%），异性FS对显示出最低的重叠（27%），朋友对（48%）接近平均值（53%）。社会接触变量和自我报告的关系亲密度预测了同伴重叠的额外差异。基因型-环境相关性和共享的环境过程中的兄弟姐妹-同伴连接的作用进行了讨论。
Research suggests that sibling–peer connections are important for understanding adolescent problem behaviors. Using a novel behavioral genetic design, the current study investigated peer network overlap in 300 child–child pairs (aged 7–13 years) in 5 dyad types: monozygotic (MZ), dizygotic twins, full siblings (FSs), friend pairs, and virtual twins (i.e., same‐aged, genetically unrelated siblings). Genetic relatedness, sex composition, and age differences contributed to peer overlap in sibling dyads. MZ twins showed the highest overlap (82%), opposite‐sex FS pairs showed the lowest overlap (27%), and friend pairs (48%) were close to the mean (53%). Social contact variables and self‐reported relationship intimacy predicted additional variance in peer overlap. The roles of genotype–environment correlational and shared environmental processes in the sibling–peer connections are discussed.
