Social perspective-taking (SPT), which involves the ability infer others' intentions, is a consequential social cognitive process. The purpose of this study is to evaluate the psychometric properties of a web-based social perspective-taking (SELweb SPT) assessment designed for children in kindergarten through third grade. Data were collected from two separate samples of children. The first sample included 3224 children and the second sample included 4419 children. Data were calibrated using Rasch dichotomous model (Rasch, 1960). Differential item and test functioning were also evaluated across gender and ethnicity groups. Across both samples, we found: evidence of consistent item fit; unidimensional item structure; and adequate item targeting. Poor item targeting at high and low ability levels suggests that more items are needed to distinguish low and high ability respondents. Analyses of DIF found some significant item-level DIF across gender, but no DIF across ethnicity. The analyses of person measure calibrations with and without DIF items evidenced negligible differential test functioning (DTF) across gender and ethnicity groups in both samples.
社会观点采择（SPT）涉及推断他人意图的能力，是一个重要的社会认知过程。本研究的目的是评估一种为幼儿园至三年级儿童设计的基于网络的社会观点采择（SELweb SPT）评估的心理测量特性。数据来自两个独立的儿童样本。第一个样本包括3224名儿童，第二个样本包括4419名儿童。数据使用拉施二分模型（拉施，1960）进行校准。还对不同性别和种族群体的项目差异功能和测试功能进行了评估。在两个样本中，我们发现：项目拟合一致的证据；单维项目结构；以及适当的项目定位。在高能力和低能力水平上项目定位不佳表明需要更多项目来区分低能力和高能力的受访者。差异项目功能分析发现，不同性别之间存在一些显著的项目水平差异，但不同种族之间不存在差异。对包含和不包含差异项目功能项目的个体测量校准分析表明，两个样本中不同性别和种族群体之间的差异测试功能（DTF）可以忽略不计。
