Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this proposed trial will modify an existing toothbrushing app for teens with autism and compare toothbrushing outcomes with a control app. We have 2 specific aims:

* During the 2-year UG3 phase, we will use the Discover, Design+Build, and Test Framework to modify our existing app and pilot the intervention.
* During the 4-year UH3 phase, we will recruit 270 pre-adolescents and teens with autism ages 10 to 17 years, randomize participants to one of two arms, and compare outcomes.

Participants will asked to use the app, complete surveys on REDCap, participate in feedback interviews and focus groups. Behavior change in the experimental group will be compared with that in the control group.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Adolescents with autism are at increased risk for tooth decay in part because of poor diet and toothbrushing habits. Effective ways to reduce added sugar intake have yet to be tested, but technologies exist to help improve toothbrushing. Mobile health apps are a promising but underutilized way to improve and enforce toothbrushing habits. Many adolescents with autism are enamored with technology and own devices that support apps. We propose a Stage II efficacy trial in modifying a toothbrushing app and inform behavior change in the target population.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomly selected in the experimental and the control arm. Participants in the experimental arm will use the experimental app while those in the control arm will use the control app. Participants will receive all surveys in the same format and frequency in both arms.

Primary Study Purpose

PREVENTION

Blinding Strategy

DOUBLE

Investigators Outcome Assessors

The Investigator and Outcomes Assessor will be blinded to allocation. Both arms will be described as interventions (educational versus behavioral). At the end of the trial children will be able to access the app in the other arm free of charge. The Outcomes Assessor (Statistician) will be masked to group assignment and unblinded only after the final analyses are completed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental

Children in the experimental arm will receive the same health education module as in the control arm. They will also receive a brief tutorial on additional app components in the form of a digital social story, which is an effective way to convey information to children with autism. Participants will be completing 26-item Behavioral Survey at 2 weeks, 1 month, 2 month, and 3 month. Participants will be using the app during toothbrushing 2x a day for 3 months under direct supervision of the caregiver.

Intervention Type BEHAVIORAL

Information provided in arm descriptions.

Control

The control arm will consist of a 20-second health education module delivered through the control app that consists of a digital selfie mirror and a timer that matches the length of brushing time in the experimental app. Participants will be completing all the survey activities similar to that of the participants in the experimental arm.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Child participants will have Autism Spectrum Disorder that will be confirmed by: (1) chart review by clinical staff at the recruitment sites to determine if the child meets the DSM-5 criteria for autism spectrum disorder; OR (2) affirmative caregiver response (YES) to the question, "Has a healthcare provider ever diagnosed your child with autism?"
* Willingness to take a CARS-2 \[Childhood Autism Rating Scale-2\], which will be administered by trained staff
* Child brushes independently \[The child needs to be able to hold the toothbrush and move it around their teeth, mostly unassisted\]
* Child uses touch screen devices (e.g.,smartphones or tablet)
* Ages 10 to 17 years at enrollment
* Caregiver and child able to communicate in English
* Caregiver age ≥18 years and able to provide informed consent in English
* Child and caregiver live in the same home
* Child has ready access to a mobile device with a front-facing camera onto which apps can be downloaded (iPad or iPhone with iOS 16.0+; Android tablet or phone with Android 13.0+)
* Family has a Wi-Fi or cellular data plan to allow app data to be transmitted, with confirmation of via tools like the Ookla Speed Test to help problem solve and ensure that app data can be transmitted
