The preliminary acceptability, internal consistency, test-retest reliability, and validity of the Infant-Toddler Social and Emotional Assessment (ITSEA), a parent-report questionnaire concerning social-emotional problems and competencies, were examined in a sociodemographically diverse pediatric sample of 214 parents of 12-to 36-month-olds. Results supported the ITSEA's acceptability and preliminary internal consistency, test-retest reliability, and validity. Most parents had a positive response to the ITSEA, found the questions easy to understand, and would consider recommending it to a friend. Confirmatory factor analyses supported 16 conceptually hypothesized problem and competence scales. Most scales had strong internal consistency, good to excellent 2-week test-retest reliability, and moderate 1-year test-retest reliability. Significant correlations among ITSEA scales and parent reports of child temperament and problem behaviors supported the ITSEA's validity. Psychometric findings are viewed as preliminary due to the relatively small sample size. Parents reported greater competence and more maladaptive behaviors in older children than younger children. Consistent with observational studies, boys lagged behind girls in certain parent-reported competencies, including empathy, compliance, prosocial peer interactions, and emotional awareness. Parent reports yielded empirically coherent problem and competence scales and domains, suggesting the early emergence of parental perceptions of organized and differentiated clusters of social-emotional behaviors.
