The dimensionality and psychometric properties of a widely used social–emotional assessment, the Ages & Stages Questionnaires: Social–Emotional Second Edition (ASQ:SE-2), were investigated in this study using item response theory models. A comparison was conducted between a unidimensional model, reflecting a compound construct—social–emotional competence, and a multidimensional model, based on the theoretical framework that posits that social competence and emotional competence are highly related but different constructs. The result indicated that the multidimensional structure presented a better fit for the ASQ:SE-2 sample across most intervals (i.e., 6, 12, 18, 24, 30, 36, 48, and 60 months). The psychometric properties estimated by the multidimensional model reflected congruence between the levels of item difficulty and the design of the ASQ:SE-2 and indicated a high quality of items based on the fit item statistics. However, the expected a posteriori/plausible value reliability estimates for several younger age intervals (i.e., 6, 12, 18, and 24 months) did not meet the 0.70 benchmark. The relationship between the 2 dimensions presented a moderate correlation during infancy (r = .43–.56) and a stronger relationship in older ages (r = .71–.83).

评估幼儿社会情绪筛查工具的维度和心理测量特性

补充数字内容在文本中可用。社会情感能力对于儿童终生的积极发展成果很重要。本研究使用项目反应理论模型研究了广泛使用的社会 - 情绪评估，年龄和阶段问卷：社会 - 情绪第二版（ASQ：SE-2）的维度和心理测量特性。基于假设社会能力和情感能力高度相关但结构不同的理论框架，在反映复合结构——社会-情感能力的单维模型和多维模型之间进行了比较。结果表明，多维结构在大多数区间（即 6、12、18、24、30、36、48、和 60 个月）。多维模型估计的心理测量属性反映了项目难度级别与 ASQ:SE-2 设计之间的一致性，并表明基于拟合项目统计数据的项目质量高。然而，几个较年轻的年龄间隔（即 6、12、18 和 24 个月）的预期后验/合理值可靠性估计不符合 0.70 基准。这两个维度之间的关系在婴儿时期呈现出中等相关性 (r = .43–.56)，而在老年时期呈现出更强的相关性 (r = .71–.83)。几个较年轻的年龄间隔（即 6、12、18 和 24 个月）的预期后验/合理值可靠性估计不符合 0.70 基准。这两个维度之间的关系在婴儿时期呈现出中等相关性 (r = .43–.56)，而在老年时期呈现出更强的相关性 (r = .71–.83)。几个较年轻的年龄间隔（即 6、12、18 和 24 个月）的预期后验/合理值可靠性估计不符合 0.70 基准。这两个维度之间的关系在婴儿时期呈现出中等相关性 (r = .43–.56)，而在老年时期呈现出更强的相关性 (r = .71–.83)。
