This paper exemplifies a secondary data analysis of context-specific differences in children's hyperactivity-impulsivity while controlling for informant-specific effects. Participants were boys and girls from the NICHD Study of Early Child Care and Youth Development who were measured in 1(st), 3(rd), and 5(th) grades. Latent factor models were structured using multi-informant reports including mothers, fathers, teachers, and observers. Temporal stability within a context was stronger than cross-context consistency, and the magnitude of longitudinal stability was higher in the home context compared to the school context. Controlling for informant-specific effects resulted in a significantly improved model fit and increased within-context stability. Our findings highlight the importance of considering both context and informant effects when studying longitudinal stability and change in personality development.
本文举例说明了在控制信息提供者特定效应的同时，对儿童多动冲动的特定情境差异进行二次数据分析。参与者是来自国家儿童健康与人类发展研究所早期儿童保育与青少年发展研究的男孩和女孩，他们在一年级、三年级和五年级接受了测量。潜在因素模型是使用包括母亲、父亲、教师和观察者的多信息提供者报告构建的。情境中的时间稳定性强于跨情境一致性，并且家庭情境中的纵向稳定性幅度高于学校情境。控制信息提供者特定效应导致模型拟合显著改善，情境内稳定性增加。我们的研究结果强调了在研究人格发展的纵向稳定性和变化时考虑情境和信息提供者效应的重要性。
