A Psychometric Analysis of the Early Identification System–Student Report in a Sample of Southwestern U.S. Students

The Early Identification System–Student Report (EIS-SR) is a 34-item measure of social-emotional functioning that is designed to be a low-cost universal screening tool. To date, studies of the EIS-SR demonstrate promising psychometric properties, but these properties have not yet been assessed in groups of children from historically underrepresented populations. The current study seeks to help close this gap in the literature by examining the evidence of validity related to the internal structure of the EIS-SR in a sample of Grades 3 through 8 students in the southwestern United States. Analyses indicated mixed findings regarding the model fit of the EIS-SR in the obtained sample, which implies that more data regarding its measurement invariance across diverse populations are needed.
