Twin-singleton differences in problem behaviours in 2-3-year-olds were studied. Maternal ratings of children's problem behaviours were obtained with the CBCL/2-3. The twin sample consisted of 1363 twin pairs (456 MZ, 907 DZ), the sample of singletons consisted of 420 children from the general population. Results indicated that the general level of problem behaviours in twins was broadly comparable to that in singletons. Four of the seven syndromes showed lower scores for twins. These differences, however, were small and mainly caused by lower scores for DZ twins in comparison to MZ twins and singletons. Part of the difference could be attributed to the higher maternal age in the twin groups. Higher means for boys were found for the total problem score, and the Aggressive and Overactive syndromes.
对2至3岁儿童问题行为中的双胞胎与单胞胎差异进行了研究。使用儿童行为量表/2-3岁版（CBCL/2-3）获得母亲对儿童问题行为的评分。双胞胎样本包括1363对双胞胎（456对同卵双胞胎，907对异卵双胞胎），单胞胎样本包括420名来自普通人群的儿童。结果表明，双胞胎的问题行为总体水平与单胞胎大致相当。七个综合征中的四个在双胞胎中得分较低。然而，这些差异很小，主要是由于异卵双胞胎与同卵双胞胎和单胞胎相比得分较低。部分差异可归因于双胞胎组中母亲年龄较高。在总问题得分以及攻击和多动综合征方面，男孩的得分较高。
