Thousands of teenage girls participated in a new study, and what they uncovered should be deeply concerning

For nearly 20 years, I’ve focused on understanding the challenges young women face. As the founder of Ruling Our eXperiences (ROX), I’ve researched the lives of over 50,000 girls across the U.S. since starting my work in 2006. This journey has provided deep insights into girlhood in America, but it began not in a lab or office, but as an insecure preteen who experienced early puberty and felt out of place among her peers.
