Poster #203 - Dimensional Inventory for Child Development Assessment Socioemotional Scale: Validity Evidence Based on the Internal Structure

Thu, March 21, 12:30 to 1:45pm, Baltimore Convention Center, Floor: Level 1, Exhibit Hall B

Integrative Statement

Approximately 10-15% of children experience early socioemotional problems that are associated with a higher probability of exhibiting aggression and rule-breaking behaviors, and experiencing symptoms of anxiety later in adolescence (Sheldrick et al., 2013). Despite the high prevalence, socioemotional problems are rarely detected early and, therefore, rarely referred for intervention (United States Department of Health and Human Services, 2008). This study aimed to evaluate validity evidence from scores on the Inventário Dimensional de Avaliação do Desenvolvimento Infantil (IDADI; Dimensional Inventory for Child Development Assessment) Socioemotional Scale. To achieve this aim, a sample of 2,189 children, with a mean age of 37.96 (SD = 23.39) months, were assessed. IDADI is an inventory developed in Brazil that assesses child development based on mothers’ report. The Socioemotional Scale contains 83 items divided according to increasingly sophisticated skills developed by children over time. Skills assessed include behavioral and emotional regulation, empathy, attachment, and ability to establish and maintain social relationships with familiar and unfamiliar people of different ages. Results from Rasch analysis provide supporting internal consistency evidence and optimal participant discrimination. Person separation was 6.1 and reliability was 0.97. Items provided a comprehensive measure of the socioemotional continuum with an item separation of 29.1 and reliability of 0.99. Average item fit was 0.96 for infit and 1.53 for outfit. Evidence suggested unidimensionality with 63% of the variance explained by the model and 1.7% of the residual variance explained by the first contrast (Table 1). Besides, scores were highly associated with age (Figure 1).These findings provide support for the Socioemotional Scale of IDADI based on evidence of strong internal structure and reliability of scores.
