Care Improving Cognition for ADolescents on the Autism Spectrum (CICADAS)

Participants assigned to Arm A will engage in CICADAS app only for the first 16 weeks of the intervention period. After the completion of the first intervention period and the mid-intervention assessment (V3) visit, these participants will then be assigned to No-Contact (no active intervention) for the second 16 weeks of the intervention period.

Participants assigned to Arm B will engage in PEERS + CICADAS for the first 16 weeks of the intervention period. After the completion of the first intervention period and the mid-intervention assessment (V3) visit, these participants will then be assigned to No-Contact (no active intervention) for the second 16 weeks of the intervention period.

Participants assigned to Arm C will engage in PEERS + Active Comparator for the first 16 weeks of the intervention period. After the completion of the first intervention period and the mid-intervention assessment (V3) visit, these participants will then be assigned to No-Contact (no active intervention) for the second 16 weeks of the intervention period.

Participants completed baseline assessments and neuroplasticity-based targeted cognitive training (NB-TCT) exercises on a digital device for up to 40 hours through BrainHQ (Posit Science Corporation, San Francisco). The CICADAS app captures user-specific sensory and cognitive processing metrics through 10 brief computerized assessments; these data are used to guide and personalize the delivery of 13 NB-TCT exercises. The NB-TCT exercises are adaptive with the task difficulty adjusting on a trial-to-trial and session-by-session basis to the abilities of each individual. A second set of computerized assessments was administered following the intervention period. Participants had to log in to access these assessments and exercises using a study provided username that contained no personally identifiable information.

Participants will complete both PEERS and CICADAS study activities.

The CICADAS app captures user-specific sensory and cognitive processing metrics through 10 brief computerized assessments; these data are used to guide and personalize the delivery of 13 NB-TCT exercises. In addition, participants will be asked to attend weekly 1-hour group sessions led by a PEERS clinician. Each PEERS group session will consist of a minimum of 3 participants and will meet as a group using Zoom. PEERS teaches how to solve real-life social dilemmas, appraise affect and social contexts, and initiate and maintain conversations while receiving feedback from peers and clinicians. After 16 weeks, participant will crossover to No-Contact with no active intervention.

Participants will complete both PEERS and Active Comparator study activities. Participants will engage in computerized, casual video games for a total of 40 hours. Participants will also complete the 10 sensory processing abnormalities (SPA) computerized assessments.
