Traits in Transition: The Structure of Parent‐Reported Personality Traits from Early Childhood to Early Adulthood

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. We addressed these issues by analyzing personality parent reports describing a cross‐sectional sample of 16,000 children, adolescents, and young adults (ages 3 to 20). These parent reports were made using a broadband measure of youths' personal characteristics, the common‐language California Child Q‐Set. Analyses of the full sample and comparisons of 16 age groups supported three main conclusions. First, the hierarchical structure of youths' personality traits both resembles and differs from the adult personality hierarchy in important ways. Second, a set of six dimensions—Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness to Experience, and Activity—may constitute the foundational level of the youth personality hierarchy from middle childhood through adolescence. This “Little Six” structure represents a union of the most prominent personality and temperament dimensions. Third, the meanings of some youth personality dimensions (e.g., Activity, Conscientiousness) shift systematically with age. These findings advance our understanding of when and how personality structure develops during the first two decades of life.     

Long-term stability in the Big Five personality traits in adulthood

This study investigated the stability of the Big Five personality traits in adulthood from age 33 to 42. Participants (89 men, 103 women) were drawn from the ongoing Jyväskylä Longitudinal Study of Personality and Social Development. The results showed that the mean‐level of Neuroticism decreased whereas the mean‐level of Extraversion, Openness to Experience, Agreeableness, and Conscientiousness increased from age 33 to 42. The Structural Equation Modeling analyses revealed both gender differences and similarities in the rank‐order stability of the Big Five: Neuroticism and Extraversion were more stable in men than in women, whereas Openness to Experience, Agreeableness, and Conscientiousness were as stable in men as in women. Stability coefficients for the Big Five personality traits across 9 years were moderate to high, ranging from 0.73 to 0.97 in men and from 0.65 to 0.95 in women. The highest gender‐equal stability was found for Openness to Experience and the lowest for Conscientiousness.     

Big Five personality development in adolescence and adulthood

The present article examines Big Five personality development across adolescence and middle adulthood. Two adolescents and their fathers and mothers from 285 Dutch families rated their own and their family members' personality. Using accelerated longitudinal growth curve analyses, mean level change in Big Five factors was estimated. For boys, Extraversion and Openness decreased and for girls, Extraversion, Agreeableness, Conscientiousness, and Openness increased. Whereas mothers' Emotional Stability and Conscientiousness increased, fathers' Extraversion, Agreeableness, and Emotional Stability decreased. Differences in self‐ and other‐reported personality change were found, as well as interindividual differences in personality change. Results confirm that personality change is possible across the life course but these changes are not similar for all individuals and depend on the type of observer.

Personality trait development from age 12 to age 18: longitudinal,cross-sectional,and cross-cultural analyses

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.

Cross-sectional age differences in personality: Evidence from nationally representative samples from Switzerland and the United States

Identifying reliable patterns of age differences in personality can help clarify the nature of adult personality development. Previous studies have been limited because many have relied on convenience samples. In this study, we examined age differences in personality in two nationally representative samples, one from Switzerland and one from the United States. The results indicated that Agreeableness and Conscientiousness were positively associated with age, whereas Extraversion was negatively associated with age. However, the magnitude of age differences for Extraversion was much smaller than for Agreeableness and Conscientiousness. Openness showed a more complex trend such that 30- to 34-year-olds scored lower on Openness than younger age groups, whereas older groups scored somewhere in between. Inconsistent age differences were observed for Neuroticism.     

Big Five Personality Traits as the Predictors of Creative Self‐Efficacy and Creative Personal Identity: Does Gender Matter?

The aim of this study was to examine the relation of the Big Five personality factors to two self‐concept variables of growing importance in creativity literature: creative self‐efficacy (CSE) and creative personal identity (CPI). The analysis, conducted on a large (N = 2674, 49.6% women) and varied‐in‐age (15–59 years old) nationwide sample of Poles, using the structural equation model, demonstrated that personality factors are responsible for 23% of CSE and 21% of CPI variances. CSE and CPI were associated with all five personality dimensions: positively with Openness to Experience, Extraversion and Conscientiousness, negatively with Neuroticism and Agreeableness. The separate analyses conducted on men and women showed the differences among the predictors of CSE and CPI. Although Openness to Experience, Conscientiousness, and Neuroticism predicted CSE among both men and women, Extraversion was positively and Agreeableness negatively related to women's CSE. Conscientiousness was positively related to CPI only among men, and Agreeableness was negatively related to it only among women. Extraversion, Neuroticism, and Openness predicted CPI in the same manner among men and women.     

Personality Dimensions in Nonhuman Animals: A Cross-Species Review

The evolutionary continuity between humans and other animals suggests that some dimensions of personality may be common across a wide range of species. Unfortunately, there is no unified body of research on animal personality; studies are dispersed across multiple disciplines and diverse journals. To review 19 studies of personality factors in 12 nonhuman species, we used the human Five-Factor Model plus Dominance and Activity as a preliminary framework. Extraversion, Neuroticism, and Agreeableness showed the strongest cross-speciesgenerality, followed by Openness; a separate Conscientiousness dimension appeared only in chimpanzees, humans? closest relatives. Cross-species evidence was modest for a separate Dominance dimension but scant for Activity. The comparative approach taken here offers a fresh perspective on human personality and should facilitate hypothesis-driven research on the social and biological bases of personality.     

Personality profiles and health: Longitudinal evidence among Finnish adults

Kinnunen, M.‐L., Metsäpelto, R. L., Feldt, T., Kokko, K., Tolvanen, A., Kinnunen, U., Leppänen, E. & Pulkkinen, L. (2012). Personality profiles and health: Longitudinal evidence among Finnish adults. Scandinavian Journal of Psychology 53, 512–522. This study investigates the associations of longitudinal Big Five personality profiles with long‐term health in 304 adults (53% males). Personality traits (Neuroticism, Extraversion, Openness, Conscientiousness, Agreeableness) were assessed at ages 33, 42, and 50. Subjective (self‐rated health, symptoms, psychological distress) and objective (body mass index, waist‐to‐hip ratio, blood pressure, cholesterol, triglycerides) indicators of health were measured at ages 42 and 50. Five longitudinally stable personality profiles were extracted over 17 years by latent profile analysis. The levels of traits were the same in each profile at each age. Resilient individuals (N = 65; Neuroticism low, other traits high) had the best subjective health and Overcontrolled individuals (N = 40; Neuroticism high, other traits low) the poorest health over eight years. Reserved individuals (N = 25; high Conscientiousness, other traits low), Undercontrolled (N = 41; high Openness and Extraversion, low Conscientiousness), and Ordinary (N = 133; all traits scored medium) individuals were in the middle of these extremes in subjective health. No differences between the profiles were found in the objective indicators of health. Thus, overcontrol and resilience were most discriminative in terms of good health. Moreover, personality profiles revealed associations with health to be more nuanced than simply being composed of single traits. High Extraversion needed to be combined with high Conscientiousness (Resilients) in order to be associated with the best health; high Extraversion with low Conscientiousness (Undercontrolled) was associated with average health; and low Extraversion with high Neuroticism (Overcontrolled) was associated with the poorest health.     

Personality at midlife: stability, intrinsic maturation, and response to life events

Although developmental theories and popular accounts suggest that midlife is a time of turmoil and change, longitudinal studies of personality traits have generally found stability of rank order and little or no change in mean levels. Using data from 2,274 men and women in their 40s retested after 6 to 9 years, the present study examined two hypotheses: (a) that retest correlations should be no higher than about .60 and (b) that there should be small decreases in Neuroticism, Extraversion, and Openness, and small increases in Agreeableness and Conscientiousness. The study also explored the effects of recalled life events on subsequent personality scores. Results did not support the first hypothesis; uncorrected retest correlations uniformly exceeded .60. This was true for all personality traits, including facets of Agreeableness and Conscientiousness not previously included in longitudinal studies. The hypothesized decreases in Neuroticism, Extraversion, and Openness were found, but Conscientiousness showed a small decrease instead of the predicted increase. Life events in general showed very little influence on the levels of personality traits, although some effects were seen for changes in job and marital status that warrant further research.     

Whose “Storm and Stress” Is It? Parent and Child Reports of Personality Development in the Transition to Early Adolescence

The present study investigated Big Five personality trait development in the transition to early adolescence (from the fifth to eighth grade). Personality traits were assessed in 2,761 (47% female) students over a 3‐year period of time. Youths’ self‐reports and parent ratings were used to test for cross‐informant agreement. Acquiescent responding and measurement invariance were established with latent variable modeling. Growth curve models revealed three main findings: (a) Normative mean‐level changes occurred for youths’ self‐report data and parent ratings with modest effects in both cases. (b) Agreeableness and Openness decreased for self‐reports and parent ratings, whereas data source differences were found for Conscientiousness (decreased for self‐reports and remained stable for parent ratings), Extraversion (increased for self‐reports and decreased for parent ratings), and Neuroticism (remained stable for self‐reports and decreased for parent ratings). (c) Girls showed a more mature personality overall (self‐reports and parent ratings revealed higher levels of Agreeableness, Conscientiousness, and Openness) and became more extraverted in the middle of adolescence (self‐reports). Personality changes modestly during early adolescence whereby change does not occur in the direction of maturation, and substantial differences exist between parent ratings and self‐reports.     

Five-factor model of personality and transformational leadership

This study linked traits from the 5-factor model of personality (the Big 5) to transformational leadership behavior. Neuroticism, Extraversion, Openness to Experience, and Agreeableness were hypothesized to predict transformational leadership. Results based on 14 samples of leaders from over 200 organizations revealed that Extraversion and Agreeableness positively predicted transformational leadership; Openness to Experience was positively correlated with transformational leadership, but its effect disappeared once the influence of the other traits was controlled. Neuroticism and Conscientiousness were unrelated to transformational leadership. Results further indicated that specific facets of the Big 5 traits predicted transformational leadership less well than the general constructs. Finally, transformational leadership behavior predicted a number of outcomes reflecting leader effectiveness, controlling for the effect of transactional leadership.     

Personality and the prediction of team performance

Although much is known about personality and individuals' job performance, only a few studies have considered the effects of team‐level personality on team performance. Existing research examining the effects of personality on team performance has found that, of the Big Five factors of personality, Conscientiousness is often the most important predictor. Accordingly, we investigated the criterion validity of lower‐level Conscientiousness traits to determine whether any one trait is particularly predictive of team performance. In addition to Conscientiousness, we examined the criterion validity of the other Big Five personality factors. We found that Conscientiousness and its facets predicted team performance. Agreeableness, Extraversion and Neuroticism were not predictive of team performance, whereas Openness had a modest negative relation with team performance.

Gender differences in implicit and explicit personality traits

This article investigates gender differences in implicit and explicit measures of the Big Five traits of personality. In a high-powered study (N = 14,348), we replicated previous research showing that women report higher levels of Agreeableness, Conscientiousness, Extraversion and Neuroticism. For implicit measures, gender differences were much smaller for all, and opposite in sign for Extraversion. Somewhat higher levels of implicit Neuroticism and Agreeableness were observed in women, and somewhat higher levels of implicit Extraversion and Openness were observed in men. There was no gender difference in implicit Conscientiousness. A possible explanation is that explicit self-concepts partly reflect social norms and self-expectations about gender roles, while implicit self-concepts may mostly reflect self-related experiences.     

A psychometric evaluation of the new NEO-PIR facet scales for agreeableness and conscientiousness

The five-factor model of personality represents one of the more important developments in the area of personality theory and assessment. This empirically derived model consists of the major factors of Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness. Currently there is only one commercially available measure of these dimensions: The NEO Personality Inventory (NEO-PI). The NEO-PI measures each of these global domains as well as more specific facets of Neuroticism, Extraversion, and Openness to Experience. The new revision of the NEO-PI (NEO-PIR) now includes facet scales for Agreeableness and Conscientiousness. The purpose of this article is to provide a psychometric evaluation of these new scales using a sample of working adults and relying on both self-report and observer ratings. The results provide strong support for the reliability and construct validity of these new scales.

Cohort differences in Big Five personality factors over a period of 25 years

The notion of personality traits implies a certain degree of stability in the life span of an individual. But what about generational effects? Are there generational changes in the distribution or structure of personality traits? This article examines cohort changes on the Big Five personality factors Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience, among first-year psychology students in The Netherlands, ages 18 to 25 years, between 1982 and 2007. Because measurement invariance of a personality test is essential for a sound interpretation of cohort differences in personality, we first assessed measurement invariance with respect to cohort for males and females separately on the Big Five personality factors, as measured by the Dutch instrument Five Personality Factors Test. Results identified 11 (females) and 2 (males) biased items with respect to cohort, out of a total of 70 items. Analyzing the unbiased items, results indicated small linear increases over time in Extraversion, Agreeableness, and Conscientiousness and small linear decreases over time in Neuroticism. No clear patterns were found on the Openness to Experience factor. Secondary analyses on students from 1971 to 2007 of females and males of different ages together revealed linear trends comparable to those in the main analyses among young adults between 1982 onward. The results imply that the broad sociocultural context may affect personality factors.     

The developmental psychometrics of big five self-reports: acquiescence, factor structure, coherence, and differentiation from ages 10 to 20

How do youths' personality reports differ from those of adults? To identify the year-by-year timing of developmental trends from late childhood (age 10) to early adulthood (age 20), the authors examined Big Five self-report data from a large and diverse Internet sample. At younger ages within this range, there were large individual differences in acquiescent responding, and acquiescence variability had pronounced effects on psychometric characteristics. Beyond the effects of acquiescence, self-reports generally became more coherent within domains, and better differentiated across domains, at older ages. Importantly, however, different Big Five domains showed different developmental trends. Extraversion showed especially pronounced age gains in coherence but no gains in differentiation. In contrast, Agreeableness and Conscientiousness showed large age gains in differentiation but only trivial gains in coherence. Neuroticism and Openness showed moderate gains in both coherence and differentiation. Comparisons of items that were relatively easy versus difficult to comprehend indicated that these patterns were not simply due to verbal comprehension. These findings have important implications for the study of personality characteristics and other psychological attributes in childhood and adolescence.     

Sensory Processing Sensitivity and its association with personality traits and affect: A meta-analysis

In two Bayesian meta-analyses, we investigated associations between Sensory Processing Sensitivity (SPS) and the Big Five personality traits (MA1) as well as both Positive and Negative Affect (MA2). Moderators were age and the three SPS subscales. In MA1 (8 papers, 6790 subjects), SPS in children correlated with Neuroticism (r = 0.42) but did not with Extraversion, Openness, Agreeableness or Conscientiousness. In adults, SPS correlated with Openness (r = 0.14) and Neuroticism (r = 0.40) but did not with Extraversion, Agreeableness or Conscientiousness. In MA2 (19 papers, 5326 subjects), SPS in children correlated with Negative (r = 0.29) and Positive Affect (r = 0.21), but only with Negative Affect (r = 0.34) in adults. Developmental and measurement aspects are discussed.     

Happiness is a personal(ity) thing: the genetics of personality and well-being in a representative sample.

Subjective well-being is known to be related to personality traits. However, to date, nobody has examined whether personality and subjective well-being share a common genetic structure. We used a representative sample of 973 twin pairs to test the hypothesis that heritable differences in subjective well-being are entirely accounted for by the genetic architecture of the Five-Factor Model's personality domains. Results supported this model. Subjective well-being was accounted for by unique genetic influences from Neuroticism, Extraversion, and Conscientiousness, and by a common genetic factor that influenced all five personality domains in the directions of low Neuroticism and high Extraversion, Openness, Agreeableness, and Conscientiousness. These findings indicate that subjective well-being is linked to personality by common genes and that personality may form an "affective reserve" relevant to set-point maintenance and changes in set point over time.
