What this trial studies

The PRISM intervention focuses on maximizing language outcomes for preschoolers with Autism Spectrum Disorder (ASD) who are minimally verbal. This study employs a Sequential Multiple Assignment Randomized Trial (SMART) design to develop a two-stage, 20-week adaptive intervention approach that tailors treatment based on individual needs. Children will receive either Discrete Trial Training (DTT) or the JASPER method, with the goal of providing the most effective intervention at the right time. The study aims to recruit approximately 140 children across three sites, utilizing community settings for intervention delivery.

Who should consider this trial

Good fit: Ideal candidates are children aged 36-59 months with a diagnosis of ASD who use fewer than 20 functional words and have received prior early intervention.

Not a fit: Patients with sensory and motor impairments or known genetic syndromes will not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve language skills in preschoolers with ASD, reducing the likelihood of being classified as minimally verbal.

How similar studies have performed: Previous studies have shown success with similar interventions, particularly in using adaptive approaches for children with ASD.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* children meeting ADOS-2 criteria for ASD,
* age 36-59 months
* who have had \> 3 months early intervention/preschool (to ensure that children already have been exposed to some community interventions) and
* use \< 20 functional words (i.e., non-echoed, non-scripted).

Additional inclusion criteria are:

* stable medication over the past 6 months, and
* nonverbal mental age of \>12 months on the Mullen Scales of Early Learning (visual reception and fine motor subscales).

Exclusion Criteria:

* We will exclude children who have sensory and motor impairments (e.g., visual impairment, deaf or hard of hearing) and with known genetic syndromes (e.g., Down Syndrome).
* We will not exclude on the basis of AAC exposure, but expect few will be exposed at these ages.
