Teenagers in particular are influenced by peers for decisions about clothes, music, social events and behaviors, dating, academic enthusiasm, and after-school activities. A child's peer group helps to develop feelings of security and acceptance in social settings. Teenagers who do not find love, acceptance, and emotional support within their family become more vulnerable to influences from their friends and are more likely to imitate their peers' behaviors. Peer pressure can also be positive by encouraging a child to do his best, discouraging a class bully, and providing valuable friendship. Characteristics that will help a child stand up to undesirable peer pressure include healthy self-esteem, a positive self-image, a sense of security, and assertive communication skills.
