What age range defines the adolescent developmental stage?

The adolescent developmental stage is defined by the age range of 12 to 18 years. This period is characterized by significant physical, emotional, and social changes as individuals transition from childhood into adulthood. During these years, adolescents experience puberty, leading to various changes in body structure and function. They also develop more complex reasoning and decision-making skills and begin to establish their own identities separate from their families.

This age range is crucial for the formation of peer relationships and gaining independence. Adolescents start to explore their values, beliefs, and personal goals, often influencing their future choices regarding education, career, and relationships. Understanding these developmental milestones is essential for healthcare professionals when assessing and supporting adolescents' health and well-being.
