相对而言，很少有研究集中在双胞胎及其同卵双胞胎之间关系的性质或含义上。我们以5268名芬兰青少年双胞胎为样本（FinnTwin16研究），研究了双胞胎兄弟姐妹之间的依赖性及其对青少年社会交往、休闲时间活动和教育程度的影响。我们发现同卵双生的依赖因合子和性别而有显著差异。母亲们也报告了依赖性的合子性和性别差异，这与双胞胎自我报告的依赖性相似。依赖性与社会交往、闲暇时间的活动、教育程度以及母亲的教育水平和父亲的社会经济地位有关。双胞胎关系的这些差异可能与不同的社会心理测量有关，在双胞胎行为特征的研究中应该考虑到这些差异。
Relatively few studies have concentrated on the qualities or implications of the relationships between twins and their co-twins. We examined dependence between twin siblings and its impact on their social contacts, leisure-time activities and educational attainment in adolescence in a population-based sample of 5268 Finnish adolescent twins (FinnTwin16 study). We found that co-twin dependence varies significantly by zygosity and gender. Mothers also reported zygosity and gender differences in dependence that were similar to the twins' self-reports of dependence. Dependence was associated with social contacts, leisure-time activities and educational attainment, as well as with mothers' educational level and fathers' socio-economic status. These differences in twin relationships might be associated with different psychosocial measures and should be taken into account in studies of twins' behavioral traits.
