Study summary

The primary objective of this research study is to improve outcomes involving core social-communication symptoms for young children with ASD or social communication delays by increasing access to clinically validated early behavioral intervention through a telehealth parent coaching model. The investigators will test the hypothesis that telehealth-delivered Naturalistic Developmental Behavioral Intervention parent coaching (TC) is non-inferior to in-person coaching (IPC) for the treatment of core social-communication symptoms in toddlers with either a social communication delay or ASD.

Read the detailed description

The primary objective of this research study is to improve outcomes involving core social-communication symptoms for young children by increasing access to clinically validated early behavioral intervention through a telehealth parent coaching model. The investigators will test the hypothesis that telehealth-delivered Naturalistic Developmental Behavioral Intervention parent coaching (TC) is non-inferior to in-person coaching (IPC) for the treatment of core social-communication symptoms in toddlers with ASD. The secondary hypothesis is that feasibility (defined as parent fidelity) of TC is non-inferior to IPC. An exploratory objective is to guide clinical decision-making for telehealth implementation by examining the heterogeneity of treatment response across the two treatment arms. The investigators will test the hypothesis that baseline child behavioral dysregulation, active engagement, developmental quotient, and parent stress moderate child social-communication outcomes.

After completing eligibility testing, eligible children will be randomized into the TC or IPC condition. Each condition will involve twice weekly coaching sessions over 8-12 weeks. At the end of the intervention period, participants will be reassessed.

Inclusion criteria

  • Meeting study criteria for ASD based on:

    • Autism Diagnostic Observation Schedule(ADOS) criteria for mild-to- moderate concern or greater (for children between 18 and 30 months) or algorithm cut-offs for ASD or autism (31-33 months),
    • -5 (DSM-5)( criteria for ASD)
    • ASD diagnosis by clinician (clinical best estimate) by study team clinical research experts
  • Meeting study criteria for social communication delay based on:

    • Scoring a T score of \<35 on Expressive Language and/or Receptive Language subscales, Nonverbal developmental quotient of > 50 (Visual Reception and Fine Motor subscales averaged) AND Visual reception > 12 months
  • Nonverbal developmental quotient (DQ) of > 63 based on the Visual Reception and Fine Motor subscales
  • Gestational age of 36-42 weeks;
  • Birth weight of > 2,500 grams;
  • Absence of identifiable neurological (e.g., epilepsy), genetic (e.g., Down syndrome, fragile X, tuberose sclerosis, neurofibromatosis) or severe sensory- motor (e.g., cerebral palsy) conditions.
  • Able to walk independently.
  • Children must produce at least three different types of intentional directed (with eye contact or pairing vocalization and gesture) nonverbal or verbal communicative acts per day, with clear and specific examples, per parent report in the Eligibility Interview.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Study arms

  • Active comparator
    Telehealth Parent Coaching (TC)

    A family-centered, collaborative coaching approach, Practice-Based Coaching (Snyder et al., 2015), will be used. Coaches will use an NDBI coaching curriculum to support parents in targeting the child social-communication skills during interactions with their toddlers with ASD or social communication delays. The duration of the coaching period is 8-12 weeks with 2 sessions per week. Parents will be coached to implement NDBI strategies during daily routines with their young child with ASD or social communication delays following the coach and parent NDBI manuals developed in the primary principal investigator's lab. Trained study coaches will join families in their homes remotely via Kennedy Krieger Institute's secure Zoom password-protected account to provide coaching.

  • Active comparator
    In-person Coaching(IPC)

    A family-centered, collaborative coaching approach, Practice-Based Coaching (Snyder et al., 2015), will be used. Coaches will use an NDBI coaching curriculum to support parents in targeting child social-communication skills during interactions with their toddlers with ASD or social communication delays. The duration of the coaching period is 8-12 weeks with sessions 2 times per week. Parents will be coached to implement NDBI strategies during daily routines with their young child with ASD following the coach and parent NDBI manuals developed in the primary principal investigator's lab. Coaching will be delivered in families' homes by trained study coaches to support parent implementation of NDBI strategies during daily life activities with their toddler with ASD or social communication delays.

Interventions

  • BehavioralEarly Achievements- Parent Coaching Intervention

    Children, along with a caregiver, will be randomized into one of two conditions to receive parent coaching guided by NDBI principles.

What researchers measure

Primary outcomes

  1. Child Duration of Joint Attention

    10 minute caregiver/child play samples will be coded using an engagement coding schema. The schema differentiates different levels of engagement. This data will be used to compare duration of engagement states at pre- and post-testing.

    Time frame: 8-12 weeks

  2. Parent Fidelity of Implementation

    Parent fidelity of implementation will be coded from the parent-child interaction sample obtained within the home at baseline and post-intervention by trained (to reliability) research assistants blind to group membership and timing of sample. This form consists of 26-items, where each item is rated using a 3-point Likert-type scale. Items reflect the key elements of Natural Developmental Behavioral Interventions (NDBI) which have been assessed in parent-implemented NDBI studies found to improve child social-communication outcomes. Ratings are based on effectiveness (well-timed, variety, developmental appropriateness) and frequency/consistency.

    Time frame: 8-12 weeks
