Maximum age (years): 84
Standard ages: CHILD
Accepts healthy volunteers: yes
Observational model: COHORT
Time perspective: PROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: children ages 31-84 months who are suspected of having autism spectrum disorder or related developmental delays and those who are typically developing.

Brief summary: The goal of this clinical study is to learn about the utility and performance of the EarliPoint System (™): Evaluation for Autism Spectrum Disorder to diagnose and assess autism spectrum disorder (ASD) in children ages 31-96 months (2.5 - 7 years chronological age).

The main questions it aims to answer are:

1. To determine the sensitivity and specificity of the EarliPoint device (test) compared to Expert Clinician Diagnosis (ECD) using gold-standard clinical reference assessments in the target age-expanded population.
2. To determine the association between the EarliPoint Verbal Ability Index score and the clinical measures of verbal ability as measured by the Differential Ability Scales (DAS-II).
3. To determine the association between the EarliPoint Nonverbal Ability Index score and the clinical measures of non-verbal abilities as measured by the Differential Ability Scales (DAS-II).
4. To determine the association between the EarliPoint Social Disability Index score and the Autism Diagnostic Observation Schedule, second edition (ADOS-II) Overall Total Score.
5. To determine the association between the EarliPoint Expressive Language Ability Index score and the clinical measures of verbal ability as measured by the Differential Ability Scales (DAS-II).
6. To determine the association between the EarliPoint Receptive Language Ability Index score and the clinical measures of verbal ability as measured by the Differential Ability Scales (DAS-II).
7. To estimate the incidence of adverse device effects associated with the use of the EarliPoint device.

Detailed description: This is a prospective, multi-center, double-blind, within-subject comparison study of Dynamic Quantification of Social-Visual Engagement (DQSVE) for diagnosis of ASD and/or related developmental delays (DD) in children ages 31 - 96 months (2.5 - 7 years chronological age). The study will enroll children suspected to have ASD (ASD-positive) and those who do not have ASD (ASD-negative). Eligible participants who sign the Informed Consent Form will be consecutively screened at each study site and enrolled in the appropriate subject group (either suspected ASD/DD or non-ASD).

The main questions it aims to answer are:

1. To determine the sensitivity and specificity of the EarliPoint device (test) compared to Expert Clinician Diagnosis (ECD) using gold-standard clinical reference assessments in the target age-expanded population.
2. To determine the association between the EarliPoint Verbal Ability Index score and the clinical measures of verbal ability as measured by the Differential Ability Scales (DAS-II).
3. To determine the association between the EarliPoint Nonverbal Ability Index score and the clinical measures of non-verbal abilities as measured by the Differential Ability Scales (DAS-II).
4. To determine the association between the EarliPoint Social Disability Index score and the Autism Diagnostic Observation Schedule, second edition (ADOS-II) Overall Total Score.
5. To determine the association between the EarliPoint Expressive Language Ability Index score and the clinical measures of verbal ability as measured by the Differential Ability Scales (DAS-II).
6. To determine the association between the EarliPoint Receptive Language Ability Index score and the clinical measures of verbal ability as measured by the Differential Ability Scales (DAS-II).
7. To estimate the incidence of adverse device effects associated with the use of the EarliPoint device.

Eligibility criteria: Subjects must meet all the following inclusion criteria to participate in this study.

1. Male or female individuals between the ages of 31 - 84 months (2.5 - 7 years chronological age) at the time of consent.
2. Generally healthy with no acute illnesses.
3. Normal or corrected-to-normal vision with visual acuity and oculomotor function sufficient to watch short videos.
4. Hearing adequate to hear information presented in age-appropriate videos of social interactions.
5. Subject and parent (or legally authorized representative) are able and agree to attend the required study visit and complete the full battery of psychometric assessments and questionnaires (electronically or in-person where required).
6. Subject's parent (or legally authorized representative) can understand information, instructions, and videos presented in the English language.
7. Subject's parent (or legally authorized representative) can read and understand the Informed Consent Form (ICF).
8. Subject's parent (or legally authorized representative) provides written informed consent allowing the child subject to participate in the study. NOTE: where able, the child subject should also provide assent.

Subjects who meet any of the following exclusion criteria are not eligible to participate in this study:

1. Known genetic disorders (e.g., Fragile X, Williams Syndrome, Tuberous Sclerosis, Muscular Dystrophy, Neurofibromatosis, Down Syndrome).
2. Severe hearing or visual impairment (e.g., congenital nystagmus, congenital cataracts, previous diagnosis of severe hearing deficits by otoacoustic emissions or auditory brainstem response), which in the opinion of the investigator, would limit the child from completing the EarliPoint eye-tracking procedure or clinical reference assessments. (Note: Corrective lenses are allowable up to a prescription of +/- 5.0.)
3. Acute illnesses likely to prevent successful or valid data collection, i.e., conjunctivitis, fever, uncontrolled allergy symptoms, etc.
4. Subject has an uncontrolled seizure disorder.
5. History or presence of a clinically significant medical disease or a mental state that might confound the study or be detrimental to the subject in the opinion of the investigator.
6. Acute exacerbations of chronic illnesses likely to prevent successful or valid data collection.
7. Receiving therapies that may affect the subject's vision, (i.e., currently receiving or have received the following therapies within 2 weeks of screening: topiramate, chlorpromazine, thioridazine, prednisone, prednisolone (including ophthalmic solutions and ointments), diphenhydramine, or hydroxyzine; or have received ophthalmic antibiotics within 3 days of screening: tobramycin, ciprofloxacin, gatifloxacin, levofloxacin, moxifloxacin and ofloxacin solutions and/or bacitracin ointment).
8. Receiving therapies that may affect the subject's ability to focus attention on the videos, (i.e., if on central nervous system stimulants, Central Nervous System (CNS) depressants, or anticonvulsants, dose must have been stable for at least 2 weeks).
9. Subject is unable or unwilling to undergo EarliPoint testing for up to 20 minutes per assessment (e.g., child has frequent tantrums and tantrums do not subside within 5 minutes).
10. In the opinion of the investigator, the subject and/or parent (or legally authorized representative) are unable, unwilling, or unlikely to comply with all study required procedures and follow-up assessments or to complete the full battery of psychometric assessments (electronically or in-person where required).
11. Subject is receiving or plans to receive any investigational drug or device for the duration of their participation in this study.
12. In the opinion of the Investigator, subject is not a suitable candidate for participation in a research study (NOTE: reason must be specified).
