NCT03883139

Brief Summary

This research study, Personalized, Responsive Intervention Sequences for Minimally Verbal Children with Autism (PRISM), is designed to maximize language outcomes for limited-language preschoolers, thereby lowering the risk of being classified as "minimally verbal" at age 6, by empirically developing a two-stage, 20-week adaptive intervention approach in a real world community settings. If found efficacious, the adaptive intervention design will capitalize on the heterogeneity and evolving status of children with ASD by providing the best intervention (DTT, JASPER and CET) for children who need it (leading to individualized sequences of intervention), only when it is needed (potentially reducing burden on children).

Outcome Measures

Primary Outcomes (1)

  • Change of spontaneous utterances (SCU) from the Language Sample throughout the study.

    To determine which intervention for slower responding children (Intensify vs. CET) produces greater increases in socially communicative spontaneous utterances (SCU; primary outcome).

    baseline (entry), 10 weeks after entry, 20 weeks after entry, 30 weeks after entry, and when child turns 6

Secondary Outcomes (3)

  • Change in Joint Engagement on the Adult-Child Interaction (ACX) over the course of the study.

    baseline (entry), 10 weeks after entry, 20 weeks after entry, 30 weeks after entry, and when child turns 6

  • Change in receptive language using the Preschool Language Scales-5 (PLS-5) throughout the study.

    baseline (entry), 20 weeks, and when child turns 6

  • Presence of word combinations in the Language Sample over the course of the study.

    baseline (entry), 10 weeks after entry, 20 weeks after entry, 30 weeks after entry, and when child turns 6

Other Outcomes (3)

  • Presence of joint attention initiations using the Early Social-Communication Scales

    baseline (entry), week 10, week 20, week 30, age 6 (follow up)

  • Track the levels of spontaneous play acts using The Structured Play Assessment-R over the course of the study.

    baseline (entry), 10 weeks after entry, 20 weeks after entry, 30 weeks after entry, and when child turns 6

  • Determine eligibility on nonverbal mental age using the Mullen Scales of Early Learning (MSEL)

    baseline (entry), week 20, and age 6 (follow up)

Study Arms (2)

JASPER

ACTIVE COMPARATOR

Child will spend 2 hours per week (2 days, 1 hour per day) for the first 10 weeks doing JASPER. If the child is an early responder, he/she will remain in the same course for the following 10 weeks. If child is a slow responder, he/she will be randomized for either combined \& enhanced treatment (CET) for 2 hours a week (2 days, 1 hour per day) or Intensified JASPER for 4 hours a week (4 days, 1 hour per day).

Behavioral: JASPER

DTT

ACTIVE COMPARATOR

Child will spend 2 hours per week (2 days, 1 hour per day) for the first 10 weeks doing DTT. If the child is an early responder, he/she will remain in the same course for the following 10 weeks. If child is a slow responder, he/she will be randomized for either combined \& enhanced treatment (CET) for 2 hours a week (2 days, 1 hour per day) or Intensified DTT for 4 hours a week (4 days, 1 hour per day).

Behavioral: DTT (Discrete Trial Training)

Interventions

JASPERBEHAVIORAL

JASPER is a developmentally anchored behavioral intervention that assumes that communication develops from social interactions in which specific social engagement strategies, symbolic representations, and early communication forms are modeled and naturally reinforced by the adult's responses to the child.

JASPER

DTT is an adult-led, highly structured, behavioral teaching approach, is considered to have the strongest evidence as a "standard of care" for young children with autism. DTT emphasizes didactic, adult-led instruction.

Eligibility Criteria

Age36 Months - 59 Months
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • 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).
  • 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).

You may not qualify if:

  • 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.
