Evaluating the Efficacy of Pathways Parent-Mediated Early Autism Intervention on Social Attention and Language

NCT05604326 | Completed

• 1 other identifier: UTD IRB 22 - 665
• Study Type: interventional
• Target: 58

Brief Summary

The goal of this clinical trial is to compare the efficacy of Pathways parent-mediated early autism intervention (Pathways) and a parent education intervention (PEI) delivered to culturally and linguistically diverse families with children 12-42 months of age suspected of or diagnosed with autism. Question 1: Is Pathways more effective than a PEI at (a) fostering the development of social orienting, joint attention, and social communication and language in children with a research diagnosis of autism and (b) relieving their parents' stress? Question 2: Is the magnitude of the relationship between early and later developing attention greater in children whose parents receive Pathways compared to children whose parents receive PEI? Question 3: Is the magnitude of the relationship between joint attention and social communication and language greater in children whose parents receive Pathways compared to children whose parents receive PEI? Participants will be randomized into 24 weeks of Pathways or PEI. Participants will receive a battery of assessments to evaluate the child's cognitive, social attention, social communication, language, and adaptive functioning, and parental stress at four different time points spaced every 12 weeks from baseline to three-month follow-up.

Outcome Measures

Primary Outcomes (5)

• Changes in child social orienting

  Assessors blind to group and time will code video recordings from two structured clinician-child interactions (CCI). Both CCIs will be recorded using an iPad or small video camera for a wide-angle view of the interaction and hidden camera eyeglasses worn by the clinician to capture the location and direction of the child's eye gaze. Change in the rate of social orienting (number of occurrences/total time engaged with the clinicians across the two structured interactions) will be measured.

  Assessed for changes every 12 weeks from baseline to 36 weeks

• Changes in child Joint attention

  Assessors blind to group and time will code video recordings from two structured clinician-child interactions (CCI). Both CCIs will be recorded using an iPad or small video camera for a wide-angle view of the interaction and hidden camera eyeglasses worn by the clinician to capture the location and direction of the child's eye gaze. Change in the rate of joint attention (number of occurrences/total time engaged with the clinicians across the two structured interactions) will be measured.

  Assessed for changes every 12 weeks from baseline to 36 weeks

• Change in child social communication

  Change in the raw scores obtained on the social, speech and symbolic composite of The Communication and Symbolic Behavior Scales- Developmental Profile (CSBS-DP) will be measured. Raw scores for the social, speech and symbolic composite range from 0-64, 0-54 and 0-53 respectively. The CSBS-DP is a direct assessment of early social communication.

  Assessed for changes every 12 weeks from baseline to 36 weeks

• Change in child language

  Change in the raw scores obtained on The Preschool Language Scales 5th Edition (PLS-5) will be measured. The PLS-5 is a standardized measure of language.

  Assessed for changes every 12 weeks from baseline to 36 weeks

• change in intentional communication

  Assessors blind to group and time will code video recordings from six minutes of a structured clinician-child interactions using the Early Communication Indicator (ECI). The ECI is a weighted measure of intentional communication.

  Assessed for changes every 12 weeks from baseline to 36 weeks

Secondary Outcomes (2)

• Changes in parenting stress

  Assessed for changes every 12 weeks from baseline to 36 weeks

• changes in child adaptive functioning

  Assessed for changes from baseline to 24 weeks and from 24-to-36 weeks

Study Arms (2)

Pathways Intervention

EXPERIMENTAL

Twenty-four weeks of a manualized Naturalistic Developmental Behavioral Intervention (NDBI) parent-mediated early autism intervention that uses a coaching model.

Behavioral: Pathways Intervention

Parent Education Intervention (PEI)

ACTIVE COMPARATOR

Twenty-four weeks of individual caregiver training without the child being present.

Behavioral: Parent Education Intervention (PEI)

Interventions

Pathways Intervention BEHAVIORAL

Pathways-trained research clinicians will conduct 90-minute weekly coaching sessions with caregivers (in English or Spanish) in the family's home or other convenient location. Caregivers will receive a written and audio version of the program manual in English or Spanish, depending on the family's home language. Sessions will review information about autism, interactional strategies, and Applied Behavioral Analysis (ABA) techniques from the program manual, demonstrate intervention strategies, and provide caregivers with practice feedback and self-reflection.

Pathways Intervention

Parent Education Intervention (PEI) BEHAVIORAL

Caregivers will access a 20-30-minute video lesson and associated handouts (in English or Spanish, depending on the parent's home language) every other week for 24 weeks. On the off week, the caregiver will meet with a trained clinician (in English or Spanish) for 30 minutes without the child. Lessons will cover autism, social attention delays, evidence-based interventions, self-regulation, talking with your child, playing with your child, principles of managing behavior, knowing your rights, and self-care. The first and last visit will occur in the family's home or another convenient location. All other visits will take place over Zoom videoconferencing software.
