Summary: <\/strong>Researchers introduced a streamlined, emoji-based screening tool designed to objectively measure the social development of preschool children. The research establishes a rapid, 9-question digital diagnostic framework for early childhood educators to evaluate children aged three to five.<\/p>\n By replacing complex, time-consuming assessments with a simplified visual scale, the project provides a highly reliable baseline to catch early developmental delays, allowing clinicians and teachers to deploy critical interventions during a child\u2019s most formative years.<\/p>\n Key Facts<\/strong><\/p>\n Source: <\/strong>NTNU<\/p>\n \u201cI wanted to develop tests for social skills and vocabulary aimed at preschool children,\u201d says Professor Hermundur Sigmundsson at the Department of Psychology at the\u00a0Norwegian University of Science and Technology\u00a0(NTNU).<\/strong><\/p>\n The reason is that social skills and vocabulary are so important, especially for children and adolescents. Early screening is very important for early intervention if the child needs extra help.<\/p>\n The vocabulary test for18 to 24 month old children is still under development in Iceland, but the social skills test is well on its way to completion. Sigmundsson has a new article in Fronters in Education where he presents this test.<\/p>\n \u201cOur new test measures social skills in children aged 3-5. The preschool teacher uses 9 questions to evaluate the child\u2019s social skills.<\/p>\n The researchers tested this on 127 children in Iceland aged 3 to 5 years. The average was 3.8 years. Kindergarten teachers filled in the assessments.<\/p>\n The test is designed to be easy to use. The researchers used an emoji-based so-called \u201cLikert scale\u201d from 1 to 5, where 1 is a very sad face, 3 is a neutral face and 5 is a very happy face. The goal was to see if the test works, if it is stable and if it gives reliable results. The results are encouraging.<\/p>\n \u201cWe see that the test is well suited for children in this age group. All the questions relate to the overall result, and the correlations were good,\u201d says Sigmundsson.<\/p>\n To check whether different teachers arrive at approximately the same results, 10 children were assessed by two different early childhood educators. The comparison showed good agreement between the results from the two educators who assessed the children. The scale gives a score of 0.89 on the Cronbach scale, which indicates that it is reliable.<\/p>\n All in all, this looks promising, and it suggests that the test can be further developed.<\/p>\n \u201cThe next step is to try it on more children, and to check that it works just as well in larger and more representative groups,\u201d says Sigmundsson.<\/p>\n A<\/strong>: Because when it comes to early childhood screening, simplicity is a superpower. Traditional psychological forms are often dense, time-consuming, and highly prone to subjective interpretation. By translating behavioral markers into a stark, visual 1-to-5 emoji scale (from very sad to very happy), NTNU has stripped away the jargon. It allows busy preschool teachers to quickly log clear, intuitive observations that map directly onto mathematical data.<\/p>\n<\/div>\n A<\/strong>: In behavioral science, a Cronbach alpha score measures internal consistency and reliability, with 1.0 being absolute perfection. Scoring a 0.89 is an exceptionally high clinical baseline. It proves that the 9 questions aren\u2019t random; they are deeply interconnected and stable. Crucially, it means that if two entirely different teachers evaluate the same child, they will arrive at the exact same objective score, eliminating guesswork.<\/p>\n<\/div>\n A<\/strong>: The initial trial on 127 children yielded highly encouraging, stable results, but the project is still scaling up. Professor Sigmundsson noted that the next immediate milestone is testing the emoji framework across much larger, more diverse, and representative cohorts to ensure its universal accuracy. Once these macro-trials are complete, it can be widely distributed as a standard clinical app for classrooms globally.<\/p>\n<\/div>\n<\/div>\n Author:\u00a0<\/strong>Nancy Bazilchuk<\/a>\n
