Psychometric Properties of a Preschool Language, Literacy, and Behavior Screener

Abstract

This study investigated the psychometric properties of the Preschool Language, Literacy, and Behavior Screener (PLLB-S). We examined and tested the factor structure of the PLLB-S using exploratory and confirmatory factor analyses. We further conducted internal consistency, concurrent validity, and predictive validity analyses and evaluated teacher satisfaction using PLLB-S. Our factor analyses resulted in 22 items distributed among three subscales with high internal consistency: Oral language, emergent literacy, and behavior skills. The PLLB-S and its subscales correlated moderately to strongly with standardized measures. The emergent literacy of the PLLB-S was the only subscale that significantly predicted children’s later vocabulary knowledge. Preschool teachers reported high satisfaction with the content and purpose of the questionnaire. We concluded that this tool with sound psychometric properties can potentially help increase the feasibility and efficiency of implementing standardized assessments in MTSS frameworks in preschool classrooms.
