Virtuous character development in children is correlated with parenting behavior, but the role of genetic influences in this association has not been examined. Using a longitudinal twin/sibling study (N = 720; Time 1 (T1) M[subscript age] = 12-14 years, Time 3 (T3) M[subscript age] = 25-27 years), the current report examines associations among…

The current study focused on three aspects of identity development relevant to the adolescent years: being an authentic person, perceiving control over and consistency in one's environment, and having consistent expectations from close others. In a two-wave study of adolescents (n = 750), we examined how these aspects change over the course of a…

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 occasions across 5 years (four cohorts, 9-12 years at T1; N = 523). Correlates of, and gender differences in, type membership were examined. Latent…

We examined change and stability of the 3 personality types identified by Block and Block (1980) and studied their links with adjustment and relationships. We used data from a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents, thereby covering the ages of 12-20 years. In Study 1, systematic evidence for personality change was…

Describes a nine-year longitudinal study of childhood temperament dimensions and mothers' child rearing attitudes. Discusses the measures studied and the models used for analysis. Suggests that the development of temperament is influenced by the mother's hostile parenting attitudes as well as childhood temperament and that there are sex-related…

Assessment of the relationship between ontogenetic (individual) and generational (historical) change in adolescent personality development was the focus of this study. The total sample included 1000 male and female adolescents (ages 13-18) randomly drawn from 32 public school systems in West Virginia following a design using longitudinal sequences…

Examines whether relationships can be demonstrated between specific infantile comfort habits and later personality development. Results suggest that children with a persistent oral habit at age 4 may later (at age 11 and 16) be less emotionally "well-adjusted" and more difficult for their parents to influence and control.

Examined relationships between adolescent emotional and behavioral problems and late adolescent personality in a longitudinal study. Found that psychological distress and behavioral problems experienced during adolescent years of 7th to 10th grade are significantly related to personality structure during the final year of high school.

The nature of adolescent trait change appears less dictated by are-related components than by the type of social change patterns which are setting the environmental milieu for adolescents of all ages over a given period of time. (Authors)

In a study of eating problems in adolescent girls, researchers saw 193 White adolescent females and their mothers in the girls' middle school years and two years later. Examined was the emergence of eating problems as a function of pubertal growth, body image, personality development, and family relationships. (RH)

The authors examined the prediction of occupational attainment by age 40 from contextual and personal variables assessed during childhood and adolescence in 2 participant samples: (a) the Columbia County Longitudinal Study, a study of 856 third graders in a semirural county in New York State that began in 1960, and (b) the Jyvaskyla Longitudinal…

Describes the results of four longitudinal studies of adolescent development that focus on coping styles, maturity of defenses, adaptation to school environments, and predictors of educational and occupational attainment. Implications are discussed in terms of linking adolescence with other phases of development. (Author/SS)

Personality stability and change in sibling status in the one- and two-child-family are examined in this Study. Q-sort data were analyzed for the same 33 male and 34 female subjects during four periods of their lives-- early and late adolescence and early and middle adulthood. Results indicate that stability of personality was greatest during…

Used a longitudinal sibling research design and a large, nationally representative sample of 15- to 22-year-old siblings to study shared and unshared environmental influences on delinquency. Although no unshared family environmental influences were found for sisters and mixed-sex siblings, they may have existed for brothers. Data suggested…

This paper reports the results of an ongoing study of individuals' ego control and ego resiliency. The study began with 130 subjects in 1969 when the subjects were in nursery school. At the most recent assessment, 104 participants still remained. Ego control is defined as the degree and kind of control individuals exert over their impulses, and…
