Abstract

This study used item response theory (IRT) methods to investigate group differences in responses to the 12-item Student Risk Screening Scale–Internalizing and Externalizing (SRSS-IE12) in a sample of 3,837 U.S. elementary school students. Using factor analysis and graded response models from IRT methods, we examined the factor structure and the item and test functioning of the SRSS-IE12. The SRSS-IE12 internalizing and externalizing factors reflected the hypothesized two-factor model. IRT analyses indicated that SRSS-IE12 items and tests measure internalizing and externalizing traits similarly across students from different race, ethnicity, gender, and elementary level (K–Grade 2 vs. Grades 3–5) groups. Moreover, the mostly negligible differential item functioning (DIF) and differential test functioning (DTF) observed suggest these scales render equitable trait ratings. Collectively, the results provide further support for the SRSS-IE12 for universal screening in racially diverse elementary schools.

SRSS-IE12在种族、民族、性别和小学水平上的差异项目和测试功能

本研究采用项目反应理论（IRT）方法，以3837名美国小学生为样本，调查了对12个项目的学生风险筛查量表（SRSS-IE12）反应的群体差异。使用因子分析和IRT方法的分级反应模型，我们检查了SRSS-IE12的因子结构、项目和测试功能。SRSS-IE12的内化和外化因素反映了假设的双因素模型。IRT分析表明，SRSS-IE12项目和测试对来自不同种族、民族、性别和小学水平（K-2年级与3-5年级）的学生的内化和外化特征进行了类似的测量。此外，观察到的差异项目功能（DIF）和差异测试功能（DTF）大多可以忽略不计，这表明这些量表提供了公平的特质评级。总的来说，研究结果为SRSS-IE12在种族多样的小学进行普遍筛查提供了进一步的支持。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
