We аre becоming increаsingly wоrried аbоut kids’ socialization skills after the pandemic. We are working with a group of kids (ages 7-10). We assign one group of kids to the socialization group where they play board games, playground games, and participate in interactive group activities. Another group of kids (ages 7 -10) reads silently or plays independent video games. We believe those in the socialization group will gain more friends and learn better social skills. We want to determine if this program should be rolled out in other schools or nationwide. Please define and discuss intent to treat vs. treatment on the treated with an example.
