What best describes the influence of peer groups on adolescent values and behavior?

• A. They provide norms and support that shape identity and risk behaviors
• B. They have little to no influence
• C. They replace family influence completely
• D. They only affect fashion choices

Answer: (A)

The main idea is that peer groups strongly shape how adolescents think about themselves and how they act by providing shared norms and social support. When teens spend time with peers, they look to the group to define what’s acceptable, how to respond in social situations, and what risks are worth taking. This social guidance can steer identity development—who they see themselves as—and influence whether they engage in risky behaviors, especially if those behaviors are modeled or rewarded within the group.

Context helps here: peer influence works through conformity pressures, learning from others’ behaviors, and who the teen has chosen as friends. At the same time, family influence remains important, but peers offer a distinct and powerful force during adolescence as the desire for belonging and autonomy grows.

That description—peers providing norms and support that shape identity and risk behaviors—best captures the breadth of their impact. While some might think peers have little influence, replace family completely, or only affect fashion, these ideas don’t fit the broader way peers guide values and decisions in adolescence.
