Data from three NIH Environmental influences on Child Health Outcomes (ECHO) Program cohorts that collected the HOME-Infant-Toddler (HOME-IT age 0-3 years) version were used to examine the reliability of a brief scale of caregiver support and cognitive stimulation. Participants with HOME-IT data (N = 2518) were included in this analysis. Mean child age at HOME-IT assessment was 1.51 years, 48% of children were female, and 43% of children identified as Black. A four-stage analysis plan was used to evaluate item response theory assumptions, item response theory model fit, monotonicity, scalability, item fit, and differential item functioning. Results indicate the feasibility of developing a reliable 10-item scale (reliability >0.7) with particularly high precision for children with lower levels of cognitive stimulation.
利用美国国立卫生研究院儿童健康成果环境影响（ECHO）计划三个队列的数据（收集家庭环境评估-婴儿和学步儿版，HOME-IT，年龄 0-3 岁），本研究旨在检验一个简短的照料者支持和认知刺激量表的信度。本分析纳入了具有 HOME-IT 数据的参与者（N=2518）。HOME-IT 评估时儿童的平均年龄为 1.51 岁，48%的儿童为女性，43%的儿童为黑人。采用四阶段分析计划评估项目反应理论假设、项目反应理论模型拟合、单调性、可扩展性、项目拟合和项目间差异。结果表明，对于认知刺激水平较低的儿童，开发一个具有 10 个项目的可靠量表（信度>0.7）具有可行性，该量表对认知刺激水平较低的儿童具有特别高的精度。
