During adolescence, preteens and teens going through puberty become increasingly conscious of their body image. They develop their sexual, gender, and ethnic identities. Peer relationships become increasingly important. School responsibilities increase and some teens get a job. Many teens experiment with drugs and alcohol. The teen years have unique stresses and pressures. Teens may not always let on—but parents and other caring adults play a vital role in providing support and helping teens achieve their best on their way to adulthood.
