Social-emotional comprehension includes the ability to encode, interpret, and reason about social-emotional information. The better developed children's social-emotional comprehension, the more positive their social interactions and the better their peer relationships. Many clinical tools exist to assess children's social behavior. In contrast, fewer clinically interpretable tools are available to assess children's social-emotional comprehension. This study evaluated the psychometric properties of a group of direct assessments of social-emotional comprehension. Scores on these assessments reflected children's performance on challenging tasks that required them to demonstrate their social-emotional comprehension. In 2 independent samples, including a general education school sample (n = 174) and a clinic sample (n = 119), this study provided evidence that (a) individual assessments yield variably reliable scores, (b) composite scores are highly reliable, (c) direct assessments demonstrate a theoretically coherent factor structure and convergent and discriminant validity, and (d) composite scores yield expected age- and diagnostic-group differences. Implications for clinical practice, theory, and assessment development are discussed.
