Adolescent Personality Development: Three Phases,Three Courses and Varying Turmoil. Findings from the Toronto Adolescent Longitudinal Study

Abstract

The Toronto Adolescent Longitudinal Study was launched in 1977 to examine personality development in a non-clinical sample of children from ages ten through 19 over an eight year period. Following a description of their conceptualized model of personality and of the nature of the study, the authors summarize their findings which suggest new perspectives in three areas of adolescent personality development: 1) the subphases of adolescence, 2) the routes of passage through which adolescents proceed, and 3) adolescent turmoil.
