To explore the relations of adolescents externalizing problem behavior to genetic and environmental factors through twin study.
The externalizing problem behavior of 66 twin pairs from Chongqing City( aged from 12 to 18years) were investigated with the Youth Self-Report( YSR). The Parenting Styles and Dimensions Questionnaire( PSDQ) and Family Stresses Questionnaire( FSQ), Family Adaptability and Cohesion Scale( FACES) and Stressful Life Event( SLE) were applied to assess their environment factors. The blood sample was collected to identify zygosity oftwins. Structural equation modeling( SEM) was performed to evaluate the relations of adolescents externalizing problem behavior to the additive genetic factors( A), shared environment factors( C) and individual specific environmental factors( E).
The effects of A and E on adolescent externalizing problem behavior were 0. 57( 95% CI 0. 37-0. 72) and 0. 43( 95% CI 0. 28-0. 63), respectively. There were significantly negative correlation between externalizing problem behavior and family cohesion( r =-0. 221, P <0. 05), the scores of adolescent externalizing problem behavior were positively correlated with the scores of family stresses( r = 0. 226, P < 0. 05), the scores of stress life events( r = 0. 194, P < 0. 05), the scores of Authoritarian-parenting-style( r = 0. 235, P <0. 05), the scores of Permissive-parenting-style( r = 0. 212, P < 0. 05). The scores of adolescents externalizing behavioral problems were not significantly correlated with the parenting education level and occupation.
Adolescents externalizing problem behavior are influenced by additive genetic factors and individual specific environmental factors. Additive genetic factors play an important role. Family environment and parental rearing-pattern also have correlation with externalizing behavioral problems.
通过双生子研究探讨青少年外化问题行为与遗传和环境因素的关系。
采用青少年自评量表（YSR）对重庆市66对12至18岁双生子的外化问题行为进行调查。应用父母教养方式及维度问卷（PSDQ）、家庭压力问卷（FSQ）、家庭亲密度和适应性量表（FACES）及生活应激事件（SLE）评估其环境因素。采集血样以确定双生子的合子类型。采用结构方程模型（SEM）评估青少年外化问题行为与加性遗传因素（A）、共享环境因素（C）和个体特异性环境因素（E）的关系。
A和E对青少年外化问题行为的影响分别为0.57（95%CI 0.37 - 0.72）和0.43（95%CI 0.28 - 0.63）。外化问题行为与家庭亲密度呈显著负相关（r = -0.221，P < 0.05），青少年外化问题行为得分与家庭压力得分呈正相关（r = 0.226，P < 0.05）、生活应激事件得分呈正相关（r = 0.194，P < 0.05）、专制型教养方式得分呈正相关（r = 0.235，P < 0.05）、放任型教养方式得分呈正相关（r = 0.212，P < 0.05）。青少年外化行为问题得分与父母受教育程度和职业无显著相关性。
青少年外化问题行为受加性遗传因素和个体特异性环境因素影响。加性遗传因素起重要作用。家庭环境和父母教养方式也与外化行为问题相关。
