Brief Summary
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.

Outcome Measures
Primary Outcomes (2)
Diagnostic accuracy of the TAP
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
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 Outcomes (4)
Family perceptions of tele-assessment
Baseline
Family satisfaction with diagnostic services
Baseline and six-month follow-up
Family empowerment
Baseline and six-month follow-up
Child service access and utilization
Baseline to six-month follow-up
Study Arms (2)
Tele-assessment + in-person assessment
EXPERIMENTALParticipants 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.
Tele-assessment only
ACTIVE COMPARATORParticipants in this group will receive a tele-assessment using the TAP, followed by a second, shorter tele-assessment.
Interventions
Participants will complete a tele-assessment using the TAP. They will complete a second, shorter tele-assessment approximately two weeks later.
Participants will complete a tele-assessment using the TAP. They will complete a traditional, in-person autism spectrum disorder assessment approximately two weeks later.
Eligibility Criteria
You may qualify if:
- 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)
- 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.
You may not qualify if:
- 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).

- Masking Details
- Clinicians conducting in-person diagnostic evaluations will be blind to the outcomes of initial telehealth diagnostic appointments until after in-person assessments are administered and scored. Clinicians will be unblinded to telehealth diagnostic outcomes prior to sharing the results of in-person assessment with families. Clinicians conducting the second telehealth appointments for test-retest and interrater reliability purposes will be blind to recruitment pathway and diagnostic outcome from the initial telehealth appointment.
