摘　　要：目的:调查遗传因素和环境因素对10-16岁儿童少年行为问题的影响程度,为儿童少年行为问题的防治提供依据。方法:采用多级随机抽样的方法选取64对双生子,使用Achenbach儿童行为量表评定行为问题,估算遗传因素及环境因素对儿童少年行为问题的影响程度。结果:10-16岁儿童少年总的行为问题的遗传度为0.33,共享环境的影响程度为0.57,非共享环境的影响程度为0.10。其中退缩行为、躯体主诉、注意缺陷及违纪行为的遗传度超过0.6,共享环境对焦虑/抑郁、社交问题及攻击行为的影响程度在0.41～0.64之间。结论:遗传因素和环境因素对儿童少年的行为问题均有影响,但环境因素影响程度更大,尤其是共享环境因素。Objective： To estimate genetic and environmental contributions to behavior problems of children and adolescents aged 10 - 16 years, and to provide theoretical basis for prevention and intervention in children and adolescents＇behavior problems. Methods： A total of 64 twin pairs aged 10 - 16 years participated in this study after multistage sampling. These twin pairs＇behavior problems were assessed with the Child Behavior Checklist （ CBCL） . The genetic and environmental influences on behavior problems of children and adolescents were estimated. Results： For behavior problems of children and adolescents aged 10 to 16 years, genetic （h^2） , shared （e^2） , and non-shared environmental （ e^2 ） factors explained about 33%, 57%, and 10% respectively of the total variance. Genetic influences on withdrawn, somatic complaints, attention problems and delinquent behavior were above 60%, and shared environmental influences on anxiety/depression, social problems and aggressive behavior ranged 41 -64%. Conclusions： Both of genetic and environmental factors may play roles in behavior problems of children and adolescents, but environmental factors were more influential, especially shared environmental influences.
