Background: There’s a recognized need to reduce anxiety and depression among teenagers, a population particularly responsive to quality social interaction. The need for this study is magnified by COVID-related interruptions. The most recent National Survey of Children’s Health reports that more than 3 million adolescents aged 12-17, or approximately one in eight, has depression and/or anxiety. Research indicates that school-based interventions can be effective, particularly when using mobile applications. Ten percent of high school students in the United States reported having used illicit drugs in 2017. Substance use in teens usually leads to substance use in adulthood.
