late adolescence
Developmental period typically spanning ages 18-21, characterized by identity consolidation and preparation for adult roles.
Full Definition
Late adolescence represents the final phase of adolescent development, generally occurring between ages 18-21 years. This period is marked by continued brain maturation, particularly in areas responsible for executive function and emotional regulation. Late adolescents typically demonstrate increased capacity for abstract thinking, future planning, and intimate relationships. Health concerns during this phase often involve transition to adult healthcare systems, college health issues, and establishment of health behaviors that will persist into adulthood. Clinical care must balance recognition of emerging adult autonomy with ongoing developmental needs and vulnerability to risk behaviors.
Usage
Usage note: Use 'late adolescence' rather than 'young adult' when referring to developmental rather than chronological age categories.
