Middle childhood is a crucial juncture in the lifespan where children work towards achieving a sense of competence foundational for future development. However, middle childhood has historically been underrepresented in the personality literature. The current study provides a comprehensive examination of personality in middle childhood using a large (N = 2510), longitudinal sample of 10- to 12-year-old twins. The structure, heritability, and correlates of personality in this period were investigated using personality ratings of parents, teachers, and children. Results showed that personality in middle childhood has a coherent structure, is heritable, and is relevant for developmentally salient outcomes such as externalizing behavior, substance use, and academic engagement. Results emphasize the importance of investigating personality in middle childhood across multiple informants.
童年中期是人生中的一个关键阶段,在此期间,孩子们努力获得一种能力感,这是未来发展的基础。然而,在人格文献中,童年中期的代表性一直不足。本研究使用一个大型(N = 2510)的10至12岁双胞胎纵向样本,对童年中期的人格进行了全面考察。通过父母、教师和孩子的人格评分,研究了这一时期人格的结构、遗传性及其相关因素。结果表明,童年中期的人格具有连贯的结构,具有遗传性,并且与外化行为、物质使用和学业参与等具有发展意义的结果相关。研究结果强调了通过多个信息提供者来调查童年中期人格的重要性。
