Young children with Down syndrome (DS) often demonstrate impaired oral vocabulary development; however, few intervention studies have focused on this population. One promising method to improve the oral vocabulary of young children with DS may be to train their parents to intervene at home. In this study, we used tele-education methods (e.g., videoconferences, email) to coach parents to implement an adapted version of Down Syndrome LanguagePlus (DSL+). Four children with DS (aged 5–6 years) participated in the multiple probe across behaviors (i.e., stories) single-case research design study. Increasing trends during baseline and data variability precluded confirmation of a functional relation; however, results indicated that all participants increased their scores on mastery measures of targeted vocabulary. Three of the four parents implemented DSL+ with high fidelity and responded favorably to social validity interviews.
