Providing a parent-administered outcome measure in a bilingual family of a father and a mother of two adolescents with ASD: brief report.

There is a need for psychometrically sound outcome measures for treatment studies that have a low burden for families and that are available in multiple languages. We have developed a language assessment in English and Spanish that parents can administer to their children at home via telehealth-delivered procedures. The current case study presents descriptive data on a single family of two parent-child dyads. Both the mother and father from a single family were trained in their primary language (Spanish) on how to administer the Expressive Language Sampling - Narration (ELS-N) in their secondary language (English) to their two English-speaking monolingual sons with ASD through telehealth-delivered procedures. Both parents learned to administer the procedures to a predetermined level of fidelity. Extension to a larger sample of bilingual families is needed for this home-based, parent-administered test; however, the present results suggest feasibility even when the language of training and administration differ.
