Penn study: Friendship group influences dating violence risk for early-maturing girls

A new Penn study found that early-maturing girls are more likely to experience physical or sexual violence in dating relationships if their friend group contains more boys. The research, published in Pediatrics, analyzed data from over 3,800 girls and confirmed that girls who developed earlier have a 14% increased risk of dating abuse.
