PY - 2022 T2 - Current Diagnosis & Treatment: Pediatrics, 26e AB - The Centers for Disease Control and World Health Organization define adolescence as the phase of life between childhood and adulthood, usually between the ages of 10 and 19 years. Adolescence is a period of rapid physical, emotional, cognitive, and social development. There is considerable variability in the pace of adolescent development, and chronological age may be a poor indicator of physical, physiologic, and emotional maturity. Most teenagers complete puberty by age 16–18 years; in Western society, however, for educational and cultural reasons, the adolescent period is prolonged to allow for further psychosocial development before the individual assumes adult status. The transition to adulthood often continues through ages 20–24 years (young adulthood). The developmental passage from childhood to adulthood includes the following steps: (1) completing puberty and somatic growth; (2) developing socially, emotionally, and cognitively, and moving from concrete to abstract thinking; (3) establishing an independent identity and separating from the family; and (4) preparing for a career or vocation.
