Assessment of Pretend Play in Preschool-Aged Children: Validation and Factor Analysis of the Affect in Play Scale–Preschool Version

The Affect in Play Scale-Preschool (APS-P) and Affect in Play Scale-Preschool-Brief Rating (APS-P-BR) versions assess cognitive and affective play processes during a 5-min standardized play task. In this study, construct validity, external validity, and factor analyses for each scale were examined in 107 preschoolers. Reliability and validity were supported. Unlike results found with school-aged samples, positive affect loaded with the cognitive variables on factor analyses of the APS-P and APS-P-BR, suggesting that negative and undefined affect might represent a separate factor in preschool-aged children. Developmental significance and implications for use of the 2 scoring versions are discussed.
