Boosting Language Outcomes of Minimally Verbal Children With ASD (BLOOM) (NCT04218331)

Predicting & Optimizing Language Outcomes in Minimally Verbal Children With Autism Spectrum Disorder: Boosting Language Outcomes of Minimally Verbal Children With ASD

๐Ÿ”ต Active, Not Recruiting Observational / Diagnostic ๐Ÿง  Behavioral & Psychological Program Sponsor: University of California, Los Angeles

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

In this project, the investigator will test the effect of augmenting an evidence based joint attention intervention (JASPER) with a motor-sound system intervention (PROMPT) compared to JASPER only on speech and language outcomes. The investigator will model change over a year to determine the percentage of children who cross the hurdle from single words to word combinations by Kindergarten. The proposed research will foster the understanding of the mechanisms underlying speech heterogeneity in ASD, thereby ultimately contributing to the development of more personalized, efficacious interventions. Upon qualification to the study (after entry assessments), the child will be randomized to receive JASPER alone (play-based intervention) or JASPER plus PROMPT (both play-based and speech-based interventions). The active intervention will last for 12 weeks, 60 minute sessions twice a week. There are assessments scheduled at entry (6.5 hours), end of study (exit-2.5 hours), 3 month follow up (2 hours), and when the child turns 6 years of age (2 hours). The total time commitment per participant is 37 hours.
