Telehealth Measures Screening for Developmental Language Disorders in Spanish-Speaking Toddlers

Background: This is the second of two studies that described the use of telehealth language screening measures for use with young Spanish-speaking children. Introduction: The purpose of this study was to describe the classification accuracy of individual telehealth language screening measures as well as the accuracy of combinations of measures used with Spanish-speaking toddler-age children from rural and underserved areas of the country. Materials and Methods: This study applied an asynchronous hybrid telehealth approach that implemented parent-structured play activities with a standard set of stimuli, and interaction with a My First Words e-book. These interactions were recorded with a mini camcorder. In addition, a traditional pen and paper parent questionnaire measure was collected. Sixty-two mostly Spanish-speaking preschool-age children and their parents participated. Twenty-two children had developmental language disorders (DLDs) and 40 had typical language development. Results: Although several of the individual measures were significantly and strongly associated with standardized language scores, only reported vocabulary had classification accuracy values that were desirable for screening for DLDs. An improvement was observed when reported vocabulary was combined with a number of different words children produced during interactions with parents. Conclusions: This research provides additional evidence showing the effectiveness of a hybrid telehealth model in screening the language development of Spanish-speaking children. More specifically, reported vocabulary combined with number of different words produced by a child can provide informative and accurate diagnostic information when screening Spanish-speaking toddler-age children for DLDs. These findings replicate the first study in showing that hybrid telehealth approaches that combine the use of video technology and traditional pen and paper surveys yield strong results, and may be a viable screening alternative when face-to-face access to a bilingual provider is not possible.
