The Bracken School Readiness Assessment (BSRA) has been used in large studies such as the Millennium Cohort Study (MCS). Important conclusions might be done regarding its reliability for the prediction of children’s school readiness taking advantage of such large-scale evaluation. Although BSRA has being largely used, few are the studies at item-level under latent approach investigating its psychometric features. Using data from 14,899 2–3-year olds who participated in the MCS, we used Bayesian confirmatory factor analysis to examine multidimensionality of the subtests of the BSRA and their consistencies, specificities, and reliabilities. We found clear indications of multidimensionality. From the 88 items, 10 showed low reliability. Future research may consider excluding these low reliability items to improve the psychometric properties of the BSRA and its use as multidimensional measurement tool.

Bracken 入学准备评估的心理测量特性和优化

布拉肯入学准备评估 (BSRA) 已被用于大型研究，例如千年队列研究 (MCS)。利用这种大规模评估，可以得出关于预测儿童入学准备的可靠性的重要结论。尽管 BSRA 已被广泛使用，但在潜在方法下调查其心理测量特征的项目级别的研究很少。使用来自参与 MCS 的 14,899 名 2-3 岁儿童的数据，我们使用贝叶斯验证性因素分析来检查 BSRA 子测试的多维性及其一致性、特异性和可靠性。我们发现了多维性的明确迹象。在 88 项中，有 10 项显示低可靠性。
