Study Summary
Research teams in Boston University, UCLA, and Weill Cornell will recruit 90 participants in 3 years (10 participants per site per year) and evaluate JASPER, play-based intervention, using the BOSCC and ELSA-T. Participants will be randomized to receive JASPER facilitated either by a clinician or the caregiver. After 10 weeks, the participants will be evaluated using the CGI to determine if they are "responders" or "non-responders". Nonresponders will be given a mix of clinician and caregiver-facilitated JASPER and responders will remain the course for the following 10 weeks. Coding of the BOSCC and ELSA-T will be the outcome measures and change will be evaluated throughout the study.
Primary Outcome
Dr. Tager-Flusberg's team created the ELSA, for collecting natural language samples (NLSs) from minimally to low verbal school-aged children and adolescents with ASD and developed a novel approach for deriving quantitative measures of linguistic communication (frequency of child utterances and number of conversational turns), in real-time from the language samples that could be useful for a range of clinical intervention trials. In this study, ELSA will be used on toddlers in this study, which h
