Do individual differences in personality traits become more or less pronounced over childhood and adolescence? The present research examined age differences in the variance of a range of personality traits, using parent reports of two large samples of children from predominantly the USA and Russia, respectively. Results indicate (i) that individual differences in most traits tend to increase with age from early childhood into early adolescence and then plateau, (ii) that this general pattern of…

Kids becoming less alike

Recent work in personality development has indicated that the magnitude of individual differences in personality increases over child development. Do such patterns reflect the differentiation of

Kids becoming less alike: A behavioral genetic analysis of developmental increases in personality variance from childhood to adolescence.

TLDR
Age trends in the variances in self- and parent-reported measures of the Big Five personality traits between Ages 8 and 18 years are estimated, pointing to the possibility that developmental processes tend to make genetically similar individuals disproportionately more alike in their personality traits over time.

Big five personality traits and common mental disorders within a hierarchical taxonomy of psychopathology: A longitudinal study of Mexican-origin youth.

TLDR
Results of the present study indicate that a hierarchical model of common mental disorders extends to Mexican-origin youth and that developmental change in Big Five personality are related to developmental changes in psychopathology.

Peer Sociometric Status and Personality Development from Middle Childhood to Preadolescence

Sociometric status, the regard that other group members confer to an individual, is one of the most ubiquitous and behaviourally relevant attributes assigned to the person by the social environment.

Resilient, undercontrolled, and overcontrolled (RUO) personality types have been identified across the lifespan and are associated with psychiatric symptoms and functioning. However, it is unknown

Thin slice derived personality types predict longitudinal symptom trajectories.

TLDR
Resilient, undercontrolled, and overcontrolled personality types are identifiable using FFM observational coding in clinically heterogeneous preschoolers and undercontrolled children demonstrated the most severe trajectories.

Traits in transition: the structure of parent-reported personality traits from early childhood to early adulthood.

TLDR
The present research was conducted to map the hierarchical structure of youths' personality traits, to identify the foundational level of this structure, and to test whether the meanings of some youth personality dimensions shift with age, to advance the understanding of when and how personality structure develops during the first two decades of life.

Hypotheses about mean-level age differences in the Big Five personality domains, as well as 10 more specific facet traits within those domains, were tested in a very large cross-sectional sample (N =

This study examined whether changes in children's self-reported Big Five dimensions are represented by (developmental) personality types, using a cohort-sequential design with three measurement

Age Differences in the Variance of Personality Characteristics

In contrast to mean–level comparisons, age group differences in personality trait variance have received only passing research interest. This may seem surprising because individual differences in

Mean-level personality development across childhood and adolescence: a temporary defiance of the maturity principle and bidirectional associations with parenting.

TLDR
Results of the present study show that personality change is not directed at increasing maturity from childhood to mid-adolescence and that it elicits and is shaped by both positive and negative parenting.

TLDR
The authors examined Big Five self-report data from a large and diverse Internet sample to identify the year-by-year timing of developmental trends from late childhood to early adulthood, and found different Big Five domains showed different developmental trends.

Personality Traits in Childhood and Adolescence

Like adults, children and adolescents can be described in terms of personality traits: characteristic patterns of thinking, feeling, and behaving. We review recent research examining how youths’
