Peer influence refers to the impact that individuals within a social group, often friends or classmates, have on each other's behaviors, attitudes, and decisions. This influence can be positive, such as encouraging healthy habits or academic success, or negative, like promoting risky behaviors or poor choices. It is particularly significant during adolescence when individuals are more susceptible to the opinions and actions of their peers. The effects of peer influence can be seen in various aspects of life, including substance use, fashion choices, and academic performance. Young people may adopt certain behaviors to fit in or gain acceptance within their group. Understanding peer influence is essential for parents, educators, and mentors to help guide youth toward positive outcomes.
