ASD Wearables Feasibility Study

Wearable devices are increasingly used to support clinical research and caregiver decision-making; however, individuals with autism spectrum disorder (ASD) may experience unique challenges related to wearable device use. Sensory sensitivities and responses to physical stimuli may affect the tolerability, comfort, and sustained use of wearable technologies in this population. As a result, understanding how adolescents with ASD interact with and perceive different wearable device designs is an important step in selecting and developing devices suitable for real-world use.

This clinical study is a comparative evaluation of wearable device use across four different device form factors-a wristband, headband, adhesive patch, and finger ring-under real-world conditions in adolescents with ASD. The study examines feasibility-related factors, including device tolerability, comfort, usability, and wearability over a two-week study period. Participants are assigned to a single device type, and data are collected to assess their experiences using the assigned wearable during daily activities.

Rather than focusing on physiological mechanisms or evaluating clinical or health outcomes, this study is designed to generate comparative information on how different wearable device designs are experienced by pediatric participants with ASD. Findings from this study are intended to inform future research, development, and selection of wearable technologies that are acceptable, practical, and suitable for use in adolescent ASD populations.

Inclusion criteria

• Provision of signed and dated informed consent and assent forms
• Stated willingness to comply with all study procedures
• Stated availability for the duration of the study
• Parent provided diagnosis of autism spectrum disorder confirmed via formalized assessment

Exclusion criteria

• Presence of acute psychiatric symptoms, such as:

• Suicidal ideation (SI)
• Homicidal ideation (HI) During the prescreening call, the researcher will ask the prospective adolescent participant, "Do you have thoughts of harming yourself or others?" and if yes, the researcher will contact the PI and contact 911 depending on acuity of situation.
