This study examines the psychometric properties, including internal consistency and item difficulty of a new measure of emotion understanding through quantitative analysis. Intercorrelations between the three subtest of the measure, correlations with age and gender, and response patterns were also examined. Emotion understanding is the ability to identify the emotions of others from facial expressions and behaviors and to understand what emotions are likely to be elicited by common social situations. Emotion understanding begins to emerge in the preschool years and serves as the foundation for social competence. The Emotion Comprehension Test (ECT) is a new measure of emotion understanding for preschoolers, which uses photographs of real children to depict natural emotional facial expressions to assess emotion identification. The measure also uses puppets to act out social situations associated with common emotions and behaviors associated with emotions. Internal consistency of the three subtests were found to be r = .699 for the Emotion Identification subtest, r = .805 for the Emotion - Situations subtest, and r = .614 for the Emotion - Behaviors subtest.
