Adolescent personality dysfunction affects 42% of 18-year-olds, with early and late adolescence being critical periods. Antisocial traits in early adolescence often evolve into more complex personality disorders by late adolescence.

Area of Science:

  • Psychology
  • Developmental Psychology
  • Psychopathology

Background:

  • Adolescence is a critical developmental period with significant psychological changes.
  • Understanding the trajectory of personality dysfunction during adolescence is crucial for early intervention.

Purpose of the Study:

  • To investigate the prevalence and developmental patterns of personality dysfunction in urban adolescents.
  • To identify specific age periods and personality clusters associated with increased risk.

Main Methods:

  • Longitudinal study of a nonclinical sample of urban adolescents.
  • Assessment of personality dysfunction across early, middle, and late adolescence (ages 13-18).

Main Results:

  • Forty-two percent of 18-year-olds exhibited personality dysfunction, with early and late adolescence identified as high-risk periods.

  • In late adolescence, a significant portion presented with histrionic, borderline, or narcissistic clusters.
  • While some dysfunction resolved, antisocial traits tended to evolve into more complex clusters, indicating developmental influences.

    • Conclusions:

    • Adolescence presents distinct periods of vulnerability for personality pathology.
    • Personality dysfunction shows variable stability, with some clusters like paranoid, schizoid, and schizotypal remaining consistent.
    • Developmental pathways are evident, with shifts from certain dysfunction types to others, particularly from antisocial traits to more complex clusters in late adolescence.
