Addressing Disparities in Autism Spectrum Disorder Diagnosis Using a Direct-to-home Telemedicine Tool
June 16, 2023 updated by: Zachary Warren, Vanderbilt University Medical Center
Addressing Disparities in ASD Diagnosis Using a Direct-to-home Telemedicine Tool: Evaluation of Diagnostic Accuracy, Psychometric Properties, and Family Engagement
The investigators propose to evaluate the use of a telemedicine tool, the TELE-ASD-PEDS (TAP), that is designed to assess for autism spectrum disorder (ASD) symptoms in toddlers.
The TAP was developed at VUMC by a team of clinical psychologists with expertise in the early identification of ASD.
The TAP has been studied in controlled laboratory settings, with high levels of family and clinician satisfaction, as well as excellent agreement with blinded comprehensive ASD evaluation.
The TAP has also been used to complete direct-to-home telemedicine assessments during the COVID-19 pandemic.
However, the investigators have not yet compared direct-to-home assessments using the TAP with gold standard, in-person ASD assessments.
It has also not yet been studied in a diverse sample of families or with providers outside of VUMC.
This study will allow the investigators to address those gaps.

Detailed Description
The investigators propose to evaluate the use of a telemedicine tool, the TELE-ASD-PEDS (TAP), that is designed to assess for autism spectrum disorder (ASD) symptoms in toddlers.
This study will recruit 360 toddlers (18-42 months of age) across two sites (VUMC and the University of California, Davis).
All toddlers will receive in-home telemedicine assessment for ASD using the TAP.
This study has two aims.
The first aim will randomize participants to receive either (1) telemedicine assessment and an in-person ASD assessment or (2) telemedicine-based assessment only.
The investigators will measure diagnostic accuracy of the TAP in comparison to gold standard, in-person ASD assessment.
The investigators will also assess test-retest reliability, inter-rater reliability, and the sensitivity, specificity, and positive predictive value of the TAP.
In the second aim, all 360 families will be followed over six months to evaluate service access, family engagement, and family perceptions of the diagnostic process.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
1 year to 3 years (Child)
Accepts Healthy Volunteers
No
Description
Inclusion Criteria for Children:
- Child between 18 and 42 months of age
- Child and primary caregiver live within a 3-hour driving radius of one of the sites (i.e., VUMC or UC Davis)
Inclusion Criteria for Caregivers:
- Age 18 years or older
- Parent or legal guardian of participating child
- Has access to technology (e.g., phone, laptop, or tablet with internet connection and audio-visual capabilities) to connect to the tele-assessment platform
- Sufficient facility with English to participate in the procedures and complete study measures.
Exclusion Criteria for Children:
- Severe sensorimotor impairment that cannot be corrected and would interfere with completion of study activities
- Medical conditions for which tele-evaluation of ASD symptoms is likely to be inappropriate or complex (i.e., rare genetic syndromes, severe epilepsy, fragile health).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Tele-assessment + in-person assessment
Participants in this group will receive a tele-assessment using the TAP and will attend a traditional, in-person evaluation for autism spectrum disorder in a clinic setting.
|
Participants will complete a tele-assessment using the TAP.
They will complete a traditional, in-person autism spectrum disorder assessment approximately two weeks later.
|
Active Comparator: Tele-assessment only
Participants in this group will receive a tele-assessment using the TAP, followed by a second, shorter tele-assessment.
|
Participants will complete a tele-assessment using the TAP.
They will complete a second, shorter tele-assessment approximately two weeks later.
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Diagnostic accuracy of the TAP
Time Frame: Baseline to completion of in-person autism evaluation, approximately two weeks
|
The investigators will compare diagnoses made from the tele-assessment using TAP to those from in-person evaluation.
We will calculate the percent agreement between diagnoses assigned in each condition.
|
Baseline to completion of in-person autism evaluation, approximately two weeks
|
Validity of the TAP
Time Frame: Baseline to completion of in-person autism evaluation, approximately two weeks
|
Validity of the TAP will be measured by assessing the psychometric properties of the tool.
Estimated performance metrics will include positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of the TAP.
|
Baseline to completion of in-person autism evaluation, approximately two weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Family perceptions of tele-assessment
Time Frame: Baseline
|
Family perceptions of tele-assessment will be measured by the Parent Perceptions of Telemedicine (PPT) survey.
The PPT is an 11-question survey.
Seven questions are measured on a three-point scale and will provide quantitative data.
Each question ranges from 1 (not true) to 3 (very true).
Possible survey scores can range from 7 to 21.
Higher scores indicate more positive perceptions of tele-assessment.
|
Baseline
|
Family satisfaction with diagnostic services
Time Frame: Baseline and six-month follow-up
|
Family satisfaction with diagnostic services will be measured by the Parent Service Satisfaction (PSS) survey.
The PSS is an 7-question survey.
Questions are measured on a three-point scale ranging from 1 (not true) to 3 (very true).
Possible survey scores can range from 7 to 21.
Higher scores indicate higher satisfaction with diagnostic services.
|
Baseline and six-month follow-up
|
Family empowerment
Time Frame: Baseline and six-month follow-up
|
Family empowerment will be measured using the Family Empowerment Scale (FES), which asks questions about caregiver self-efficacy related to understanding, navigating, and supporting their child's needs.
The FES is an 24-question survey.
Questions are measured on a five-point scale ranging from 1 (never) to 5 (very often).
Possible survey scores can range from 24 to 120.
Higher scores indicate greater self-perceived empowerment.
|
Baseline and six-month follow-up
|
Child service access and utilization
Time Frame: Baseline to six-month follow-up
|
Child service access and use will be measured using the Service Access and Utilization (SAU) questionnaire.
The questionnaires asks about receipt of Part C early intervention services as well as private therapy services.
Caregivers will complete the questionnaire at seven time points (approximately 15, 30, 45, 60, 90, 120, and 180 days following initial evaluation).
At each time point, caregivers will endorse service milestones they have reached (e.g., scheduled an evaluation with the Part C service system, created an Individualized Family Service Plan, began services).
We will calculate time to each milestone for each participant.
