BACKGROUND
Mental disorders and normal personality are interconnected domains. Recent studies highlight the dimensional and hierarchical nature of psychopathology and personality, focusing on their general factor levels. However, their relationship remains unclear.
AIMS
This study explored the etiological relationship between the general factors of psychopathology and personality from adolescence to young adulthood.
METHODS
Longitudinal data from seven national twin cohorts ( = 1,538 pairs) were collected across three waves (ages 12-22). Data was analyzed using a genetically informative random intercept cross-lagged panel model and Cholesky decomposition modeling.
RESULTS
Negligible cross-lagged effects were observed between the general factors. Both showed substantial stability, with genetic influences explaining most of the time-invariant variance. About one-quarter of genetic stability was shared.
CONCLUSION
Psychopathology and personality are distinct yet parallel domains developing through adolescence into young adulthood. Notably, change in one did not lead to change in the other.
背景
精神障碍与正常人格是相互关联的领域。近期研究强调了精神病理学和人格的维度性和层次性，重点关注其一般因素水平。然而，它们之间的关系仍不明确。
目的
本研究探讨了从青春期到青年期精神病理学和人格的一般因素之间的病因学关系。
方法
收集了来自七个国家双胞胎队列（n = 1,538对）的纵向数据，分三个阶段（年龄12 - 22岁）进行。使用遗传信息随机截距交叉滞后面板模型和Cholesky分解模型对数据进行分析。
结果
在一般因素之间观察到可忽略不计的交叉滞后效应。两者都表现出显著的稳定性，遗传影响解释了大部分时间不变的方差。约四分之一的遗传稳定性是共享的。
结论
精神病理学和人格是不同但平行的领域，从青春期到青年期不断发展。值得注意的是，一个领域的变化不会导致另一个领域的变化。
