The goal of this clinical trial is to learn whether a mindfulness-based intervention can reduce depression and anxiety in autistic adolescents. The main question this trial aims to answer is: Do adolescents who complete MINDful TIME show reductions in depression and anxiety compared to an active control group? Researchers will compare adolescents who complete MINDful TIME to adolescents who are instructed to use a mindfulness meditation mobile-app to see if changes in anxiety and depression differ between the two groups.
Participants will either:
* Attend weekly 90-minute MINDful TIME group meetings through Zoom with their parent or caregiver for a total of 8-weeks and use a mindfulness meditation app daily, or
* Use a mindfulness meditation app daily for 8-weeks
All participants will:
* Attend virtual intake, baseline, and follow-up visits to complete data collection
* Complete a weekly electronic meditation diary
