Change and stability of needs from middle adolescence to young adulthood in Swedish females

Patterns of mean-level change in personality traits across the life course: a meta-analysis of longitudinal studies

The present study used meta-analytic techniques (number of samples = 92) to determine the patterns of mean-level change in personality traits across the life course. Results showed that people increase in measures of social dominance (a facet of extraversion), conscientiousness, and emotional stability, especially in young adulthood (age 20 to 40). In contrast, people increase on measures of social vitality (a 2nd facet of extraversion) and openness in adolescence but then decrease in both of these domains in old age. Agreeableness changed only in old age. Of the 6 trait categories, 4 demonstrated significant change in middle and old age. Gender and attrition had minimal effects on change, whereas longer studies and studies based on younger cohorts showed greater change.

The Same Old Song?-Stability and Change in Relationship Schemas From Adolescence to Young Adulthood

Relationship schemas are core elements of personality that guide interpersonal functioning. The aim of this study is to examine stability and change in relationship schemas across two developmental epochs-adolescence and young adulthood-in the stories that people tell about their interactions with others. Using the Core Conflictual Relationship Theme Method, relationship themes were coded from semistructured interviews conducted in adolescence and again at age 25. The sample consisted of 40 participants in a longitudinal study of adolescent and young adult psychological development. There was considerable stability in the frequency with which particular themes were expressed in the narratives of adolescents and young adults. Significant changes from adolescence to young adulthood included a decrease in the perception of others as rejecting and of the self as opposing others. Young adults saw themselves and others more positively, and used a broader repertoire of themes in their relationship narratives than they had as adolescents. The basic continuity and particular changes in relationship schemas found in this study are consistent with knowledge about the adolescent-to-young-adult transition derived from other empirical and clinical findings. Relationship schemas may be rich units of study for learning about the development of interpersonal functioning.

The rank-order consistency of personality traits from childhood to old age: a quantitative review of longitudinal studies

The present study used meta-analytic techniques to test whether trait consistency maximizes and stabilizes at a specific period in the life course. From 152 longitudinal studies, 3,217 test-retest correlation coefficients were compiled. Meta-analytic estimates of mean population test-retest correlation coefficients showed that trait consistency increased from .31 in childhood to .54 during the college years, to .64 at age 30, and then reached a plateau around .74 between ages 50 and 70 when time interval was held constant at 6.7 years. Analysis of moderators of consistency showed that the longitudinal time interval had a negative relation to trait consistency and that temperament dimensions were less consistent than adult personality traits.

Personality development during nursing education--a Swedish study

The aim of the study was to explore personality development during nursing education. The sample consisted of 122 Swedish nursing students. Ninety-three per cent of the students were female and the mean age at the beginning of the nursing education (which lasts for two years) was 27.6 years. Personality inventories were administered at the beginning and end of the education. The post-education assessment rendered several statistically significant differences of means. Compared with the pre-education assessment, the nursing students reported a more positive profession-oriented self-perception at the end of the education, a stronger ideal, real, and mirror identity, a reduced trait anxiety, stronger needs for achievement, exhibition, autonomy, dominance, and nurturance, and a weaker abasement need. The practical significance of the results was discussed.
