Purpose: In order to support evidence-based practice, this study served to evaluate the diagnostic accuracy, convergent validity, and divergent validity of the Structured Photographic Expressive Language Test-Preschool: Second Edition (SPELT-P2; J. Dawson, J. A. Eyer, J. Fonkalsrud, 2005) in order to determine whether it can be used as a valid measure for identifying language impairment in preschoolers. Method: The SPELT-P2 was administered to 54 children with typically developing language and 42 children with specific language impairment. Results: A discriminant analysis revealed good sensitivity (90.6%), good specificity (100%), and good positive and negative likelihood ratios, with a standard score cutoff point of 87 used to determine group membership. Analyses of convergent and divergent validity also supported use of the SPELT-P2 for identifying language impairment in preschoolers. Implications: The empirical evidence supports use of the SPELT-P2 as a valid measure for correctly identifying the presence or absence of language. impairment in 4- and 5-year-old preschool children.
