TL;DR: Personality factors were reasonably invariant across ages, although rank-order stability of individual differences was low and mean levels of Extraversion, Agreeableness, and Conscientiousness were stable.

Abstract: Three studies were conducted to assess mean level changes in personality traits during adolescence. Versions of the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992a) were used to assess the 5 major personality factors. A 4-year longitudinal study of intellectually gifted students (N = 230) was supplemented by cross-sectional studies of nonselected American (N = 1,959) and Flemish (N = 789) adolescents. Personality factors were reasonably invariant across ages, although rank-order stability of individual differences was low. Neuroticism appeared to increase in girls, and Openness to Experience increased in both boys and girls; mean levels of Extraversion, Agreeableness, and Conscientiousness were stable. Results extend knowledge of the developmental curve of personality traits backward from adulthood and help bridge the gap with child temperament studies.

A confirmatory examination of age‐associated personality differences: Deriving age‐related measurement‐invariant solutions using ant colony optimization
TL;DR: The results showed that even when selecting items, measurement invariance across a large age span could not be guaranteed, and the higher-order structure of personality should be accounted for when personality development is examined.

Vincent Quartier,Jérôme Rossier +1 more
TL;DR: In this paper, a cross-sectional study was designed to investigate personality in children aged 8-12 years and found that children aged 11 -12 years present higher structural congruence, higher reliabilities and higher mean correlation with parents' description than children aged eight -9 years.

Clinical significance: a statistical approach to defining meaningful change in psychotherapy research.
Neil S. Jacobson,Paula Truax +1 more
TL;DR: In this paper, the authors defined clinically significant change as the extent to which therapy moves someone outside the range of the dysfunctional population or within the ranges of the functional population, and proposed a reliable change index (RC) to determine whether the magnitude of change for a given client is statistically reliable.
An introduction to the five-factor model and its applications.

TL;DR: It is argued that the five-factor model of personality should prove useful both for individual assessment and for the elucidation of a number of topics of interest to personality psychologists.
