- The University of Texas at Dallas
- 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.
- Detailed Description
This study aims to evaluate the efficacy of all ten units of Pathways parent-coaching early autism intervention. A limitation of our previous 12-week intervention research was that in 12 weeks, we could only assess efficacy for the first five Pathways units. The first five units focus on dyadic social skills (i.e., social orienting, mutual gaze, getting the social partner's attention, and mutual imitation). The last five Pathways units (units 6-10) build on these foundational skills and focus on facilitating triadic social skills (i.e., joint attention, social communication, and language). Joint attention is an essential component of social communication and provides the context for social communication and language. Therefore, it is vital to establish the efficacy of the entire Pathways program (i.e., all ten units) on the development of social orienting, joint attention, social communication, and language.
Aim 1: To identify the effectiveness of the entire Pathways program on (a) 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.
Aim 2: To identify the relationship between early social orienting and later joint attention, social communication, and language skills.
We hypothesize that Pathways will moderate the effect of (1) growth in social orienting after receiving 12 weeks of intervention and (2) growth in joint attention and social communication and language after receiving 24 weeks of intervention. Further, we hypothesize social orienting after 12 weeks of intervention is significantly related to joint attention at 24 weeks. Finally, we expect that joint attention at 24 weeks will be significantly related to language at 36 weeks (i.e., at a 3-month follow-up). In terms of parenting stress, we expect to find a significant effect of Pathways on decreasing parent stress during the first 12 weeks of intervention, followed by a plateau.

- Primary Outcome Measures
Name Time Method Change in child language Assessed for changes every 12 weeks from baseline to 36 weeks 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.
Changes in child social orienting Assessed for changes every 12 weeks from baseline to 36 weeks 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.
Changes in child Joint attention Assessed for changes every 12 weeks from baseline to 36 weeks 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.
Change in child social communication Assessed for changes every 12 weeks from baseline to 36 weeks 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.
change in intentional communication Assessed for changes every 12 weeks from baseline to 36 weeks 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.
- Secondary Outcome Measures
Name Time Method Changes in parenting stress Assessed for changes every 12 weeks from baseline to 36 weeks Change in percentile scores obtained on Parenting Stress Index-4 (PSI-4) will be measured. PSI-4 is a standardized parent questionnaire on which parents rate agreement on 36 items using a five-point Likert scale.
changes in child adaptive functioning Assessed for changes from baseline to 24 weeks and from 24-to-36 weeks Change in raw scores obtained on Vineland Adaptive Behavior Scales, Second Edition (Vineland II) will be measured. The Vineland II is a standardized parent interview to assess adaptive functioning.
