Abstract	Purpose: To describe the concurrent validity and classification accuracy of 2 Spanish parent surveys of language development, the Spanish Ages and Stages Questionnaire (ASQ; Squires, Potter, & Bricker, 1999) and the Pilot Inventario-III (Pilot INV-III; Guiberson, 2008a). Method: Forty-eight Spanish-speaking parents of preschool-age children participated. Twenty-two children had expressive language delays, and 26 had typical language development. The parents completed the Spanish ASQ and the Pilot INV-III at home, and the Preschool Language Scale, Fourth Edition: Spanish Edition (PLS-4 Spanish; Zimmerman, Steiner, & Pond, 2002) was administered to the children at preschool centers. Results: The Spanish ASQ and Pilot INV-III were significantly correlated with the PLS-4 Spanish, establishing concurrent validity. On both surveys, children with expressive language delays scored significantly lower than children with typical development. The Spanish ASQ demonstrated unacceptably low sensitivity (59%) and good specificity (92%), while the Pilot INV-III demonstrated fair sensitivity (82%) and specificity (81%). Likelihood ratios and posttest probability revealed that the Pilot INV-III may assist in detection of expressive language delays, but viewed alone it is insufficient to make an unconditional screening determination. Conclusions: Results suggest that Spanish parent surveys hold promise for screening language delay in Spanish-speaking preschool children; however, further refinement of these tools is needed.
