Abstract

This study explored the influence of genetic and environmental factors on adolescent anxiety. Ninety-eight monozygotic and dizygotic twins from Chongqing, China (aged 15-18 years) were assessed for anxiety with the Self-Rating Anxiety Scale (SAS). The Parenting Styles and Dimensions Questionnaire (PSDQ) and Strengths and Difficulties Questionnaire (SDQ) were applied to assess environmental factors. Venous blood was drawn from the twins for zygosity determination. Structural equation modeling was performed to evaluate the effects of additive genetic factors (A), common environmental factors (C), and individual-specific environmental factors (E) on adolescent anxiety. The estimates of A and E on adolescent anxiety were 0.34 (95% CI = 0.12-0.53) and 0.66 (95% CI:0.47-0.89), respectively. The environment played an important role in adolescent anxiety. Adolescent anxiety was significantly positively correlated with peer relations (r = 0.606, p < 0.05) and negatively correlated with prosocial behavior (r = 0.207, p < 0. 05). No sex differences were observed. Adolescent anxiety was influenced by both genetic and environmental factors. The individual-specific environmental factors played an important role. Consideration of these variables will facilitate the targeted and individualized implementation of specific interventions for adolescent anxiety.

遗传和环境因素对中国青少年焦虑的影响:一项双胞胎研究
本研究探讨了遗传和环境因素对青少年焦虑的影响。研究采用焦虑自评量表(SAS)对来自中国重庆的98对单卵和双卵双胞胎(15-18岁)进行了焦虑评估。此外,还采用了 "养育方式与维度问卷"(PSDQ)和 "优势与困难问卷"(SDQ)来评估环境因素。从双胞胎身上抽取静脉血,以测定亲子关系。通过结构方程模型评估了遗传因素(A)、共同环境因素(C)和个体特异环境因素(E)对青少年焦虑的影响。A和E对青少年焦虑的估计值分别为0.34(95% CI = 0.12-0.53)和0.66(95% CI:0.47-0.89)。环境在青少年焦虑中扮演着重要角色。青少年焦虑与同伴关系呈明显正相关(r = 0.606,p r = 0.207,p

期刊介绍: The Journal of Genetic Psychology is devoted to research and theory in the field of developmental psychology. It encompasses a life-span approach, so in addition to manuscripts devoted to infancy, childhood, and adolescence, articles on adulthood and aging are also published. We accept submissions in the area of educational psychology as long as they are developmental in nature. Submissions in cross cultural psychology are accepted, but they must add to our understanding of human development in a comparative global context. Applied, descriptive, and qualitative articles are occasionally accepted, as are replications and refinements submitted as brief reports. The review process for all submissions to The Journal of Genetic Psychology consists of double blind review.
