%0 Journal Article %T Reliability, Factor Structure, and Measurement Invariance of a Web %A Clark McKown %J Journal of Psychoeducational Assessment %@ 1557-5144 %D 2019 %R 10.1177/0734282917749682 %X The purpose of this study was to evaluate the psychometric properties and measurement invariance of a web-based, self-administered battery of assessments of social-emotional comprehension called ¡°SELweb.¡± Assessment modules measured children¡¯s ability to read facial expressions, infer others¡¯ perspectives, solve social problems, delay gratification, and tolerate frustration. In an ethnically and socioeconomically diverse sample of 4,419 children in kindergarten through third grade who completed SELweb: (a) scores from assessment modules exhibited moderate to high internal consistency and moderate 6-month temporal stability; (b) composite assessment scores exhibited high reliability; and (c) assessment module scores fit a theoretically coherent four-factor model that includes factors reflecting emotion recognition, social perspective-taking, social problem-solving, and self-control. In addition, the present study supports configural and metric invariance across time, sex, and ethnicity. Analyses suggest partial scalar invariance across time, sex, and, to a lesser degree, ethnicity %K elementary school %K reliability %K validity %K social-emotional learning %K measurement equivalence %U https://journals.sagepub.com/doi/full/10.1177/0734282917749682
