• Registration Number: NCT04068688
• Lead Sponsor: Duke University

Brief Summary

Naturalistic Developmental Behavioral Interventions (NDBIs), an evidence-based early autism spectrum disorder (ASD) intervention approach, target key behaviors that help language development. While efforts to use NDBIs are increasing worldwide, important gaps in our knowledge remain on whether the behaviors targeted by NDBIs are cross-culturally valid. This study in South Africa, a multi-cultural setting, will provide critical information on NDBI treatment targets and a novel digital outcome measure of treatment response.

COVID-19 adaptations: We aim to develop and implement telehealth NDBI coaching and utilize a mixed methods approach to gather implementation and preliminary effectiveness data on the telehealth intervention.

Detailed Description

COVID-19 has significantly impacted autism spectrum disorder (ASD) clinical research and disrupted access to intervention services for children and families globally. In this ongoing study in Cape Town South Africa, a caregiver coaching Naturalistic Developmental Behavioral Intervention (NDBI) for young children with ASD has been adapted for implementation by non-specialists and implementation and clinical outcomes are being evaluated. For ongoing clinical trials, the University of Cape Town Institutional Review Board (IRB) has encouraged researchers to switch to a virtual platform, where possible. Telehealth caregiver coaching is cost-effective, increases access to rural and underserved populations, and improves understanding of family home and caregiving routines. We aim to develop and implement telehealth NDBI coaching and utilize a mixed methods approach and a longitudinal pre-post design to gather implementation and preliminary effectiveness data on the telehealth intervention.

Primary Outcome Measures

Name	Time	Method
Coordinated Joint Engagement Measured by the Joint Engagement Rating Inventory (JERI)	Baseline and Follow-up (after 12 intervention sessions, up to 3 months)	Child engagement states measured by the Joint Engagement Rating Inventory (JERI) in the ASD group; the typically developing group; and the developmental delay group. Joint Engagement Rating Inventory contains eighteen 7-point Likert scale items that characterized various aspects of joint engagement. The items were designed to span the range of possibilities likely to be observed during interactions with 18- to 30-month-old TD children as well as similarly aged and older children with developmental difficulties, including ASD. A rating of 1 indicates a very low rating and no time spent in that engagement state, 4 is the midpoint indicating the moderate time and quality of episodes in an engagement state, and 7 indicates a very high rating and high-quality engagement.
Symbol-infused Joint Engagement Measured by the Joint Engagement Rating Inventory (JERI)	Baseline and Follow-up (after 12 intervention sessions, up to 3 months)	Child engagement states measured by the Joint Engagement Rating Inventory (JERI) in the ASD group; the typically developing group; and the developmental delay group. Joint Engagement Rating Inventory contains eighteen 7-point Likert scale items that characterized various aspects of joint engagement. The items were designed to span the range of possibilities likely to be observed during interactions with 18- to 30-month-old TD children as well as similarly aged and older children with developmental difficulties, including ASD. A rating of 1 indicates a very low rating and no time spent in that engagement state, 4 is the midpoint indicating the moderate time and quality of episodes in an engagement state, and 7 indicates a very high rating and high-quality engagement.
Fluency and Connectedness Measured by the Joint Engagement Rating Inventory (JERI)	Baseline and Follow-up (after 12 intervention sessions, up to 3 months)	Caregiver-child dyadic exchanges measured by the Joint Engagement Rating Inventory (JERI) in the ASD group. Joint Engagement Rating Inventory contains eighteen 7-point Likert scale items that characterized various aspects of joint engagement. The items were designed to span the range of possibilities likely to be observed during interactions with 18- to 30-month-old TD children as well as similarly aged and older children with developmental difficulties, including ASD. A rating of 1 indicates no interaction between the dyad, a rating of 7 indicates a balanced dyadic exchange that flows naturally back and forth.
Language and Communication Developmental Quotient on the Griffiths Scales of Child Development 3rd Edition (Griffiths-III)	Baseline and Follow up (after 12 intervention sessions, up to 3 months)	The Griffiths Scales of Child Development, Third Edition (Griffiths III) is a comprehensive, developmental measure for continuous use from birth to 5 years 11 months (71 months). Although not standardized in South Africa (standardization samples are from the United Kingdom and Ireland), this developmental assessment is widely used in South Africa. The Griffiths III provides an overall measure of a child's development, as well as an individual profile of strengths and needs across five areas: Foundations of Learning; Language and Communication; Eye and Hand Coordination; Personal-Social-Emotional; and Gross Motor. Developmental quotients (DQs) were calculated by (Developmental Age/Chronological Age) \*100. Griffiths III DQs range from 1 to 100 where higher scores indicate that the child performs at or near expected chronological age as compared with a normative sample of children the same age.
Supported Joint Engagement Measured by the Joint Engagement Rating Inventory (JERI)	Baseline and Follow-up (after 12 intervention sessions, up to 3 months)	Child engagement states measured by the Joint Engagement Rating Inventory (JERI) ; in the ASD group; the typically developing group; and the developmental delay group. Joint Engagement Rating Inventory contains eighteen 7-point Likert scale items that characterized various aspects of joint engagement. The items were designed to span the range of possibilities likely to be observed during interactions with 18- to 30-month-old TD children as well as similarly aged and older children with developmental difficulties, including ASD. A rating of 1 indicates a very low rating and no time spent in that engagement state, 4 is the midpoint indicating the moderate time and quality of episodes in an engagement state, and 7 indicates a very high rating and high-quality engagement.
Response to Joint Attention (RJA) Measured by the Early Social Communication Scales (ESCS)	Baseline	Joint attention skills will be measured using the Early Social Communication Scales (ESCS) in the ASD group; the typically developing group; and the developmental delay group. The ESCS assesses nonverbal communication skills, is normed for typically developing children 18 to 30 months of age in addition to children with developmental delay expressive language level is in approximately the same range. Frequency scores for response to joint attention (RJA) will be derived from behavioral observations during a series of tasks presented by an examiner blind to child diagnosis. RJA score ranges from 0 to 20 where a higher value indicates greater response to joint attention.
Personal-Social-Emotional Developmental Quotient on the Griffiths Scales of Child Development 3rd Edition (Griffiths-III)	Baseline and Follow up (after 12 intervention sessions, up to 3 months)	The Griffiths Scales of Child Development, Third Edition (Griffiths III) is a comprehensive, developmental measure for continuous use from birth to 5 years 11 months (71 months).

The items were designed to span the range of possibilities likely to be observed during interactions with 18- to 30-month-old TD children as well as similarly aged and older children with developmental difficulties, including ASD. A rating of 1 indicates that the caregiver rarely uses the caregiver strategy to support the child's activity and language. A rating of 7 indicates that the caregiver frequently uses appropriate strategies to support and expand their child's activity and language.
Following in on a Child's Focus Measured by the Joint Engagement Rating Inventory (JERI)	Baseline and Follow-up (after 12 intervention sessions, up to 3 months)	Caregiver strategies measured by the Joint Engagement Rating Inventory (JERI) in the ASD group.

A rating of 1 indicates that the caregiver rarely uses the caregiver strategy to support the child's activity and language. A rating of 7 indicates that the caregiver frequently uses appropriate strategies to support and expand their child's activity and language.
Socialization Subscale Standard Score on the Vineland Adaptive Behavior Scales - 3rd Edition (VABS-3)	Baseline and Follow up (after 12 intervention sessions, up to 3 months)	The Vineland Adaptive Behavior Scales, Third Edition (Vineland-3) is an individually-administered measure of adaptive behavior that is widely used to assess individuals with intellectual, developmental, and other disabilities. The Vineland-3 contains 5 domains each with 2-3 subdomains. The main domains are: Communication, Daily Living Skills, Socialization, Motor Skills, and Maladaptive Behavior. The Caregiver Interview Form uses the Vineland semistructured interview technique to elicit information about the examinee's adaptive functioning from a parent or caregiver. Item responses are collected on a 3-point Likert scale with values representing 0 (never), 1 (sometimes), and 2 (usually or often) to capture frequency of target behavior. Some items require binary responses (yes/no). The VABS-3 Socialization subscale score ranges from 20-140 where a higher score indicates greater frequency of target behavior.
