Cultural and Linguistic Adaptations of Early Language Interventions: Recommendations for Advancing Research and Practice

Purpose Speech-language pathologists are responsible for providing culturally and linguistically responsive early language intervention services for legal, ethical, and economic reasons. Yet, speech-language pathologists face challenges in meeting this directive when children are from racial, ethnic, or linguistic backgrounds that differ from their own. Guidance is needed to support adaptation of evidence-based interventions to account for children's home culture(s) and language(s). This review article (a) describes a systematic review of the adaptation processes applied in early language interventions delivered to culturally and linguistically diverse populations in the current literature and (b) offers a robust example of an adaptation of an early language intervention for families of Spanish-speaking Mexican immigrant origin. Method Thirty-three studies of early language interventions adapted for culturally and linguistically diverse children ages 6 years and younger were reviewed. Codes were applied to describe to what extent studies document the purpose of the adaptation, the adaptation process, the adapted components, and the evaluation of the adapted intervention. Results Most studies specified the purpose of adaptations to the intervention evaluation, content, or delivery, which typically addressed children's language(s) but not culture. Study authors provided limited information about who made the adaptations, how, and when. Few studies detailed translation processes or included pilot testing. Only one used a comprehensive framework to guide adaptation. A case study extensively documents the adaptation process of the Language and Play Every Day en español program. Conclusions Future early language intervention adaptations should focus on both linguistic and cultural factors and include detailed descriptions of intervention development, evaluation, and replication. The case study presented here may serve as an example. Increased access to such information can support research on early language interventions for diverse populations and, ultimately, responsive service provision.
