Two Grammatical Tasks for Screening Language Abilities in Spanish-Speaking Children.

Purpose: This study assessed concurrent validity evidence for 2 grammatical tasks of a new screener, the Tamiz de Problemas de Lenguaje, for identifying monolingual Spanish-speaking children at risk for specific language impairment with grammatical deficits.

Method: A total of 770 4- to 6-year-old monolingual, Spanish-speaking children with and without language impairment were sampled from 3 different states in Mexico. Multiple logistic regression and receiver operating characteristic curve analyses were conducted to assess the predictive utility of the model and the classification accuracy of the tasks.
