Forty years on: Teachers' assessments of children's personality traits predict self-reported health behaviors and outcomes at midlife.

A life span health-behavior model was investigated in this longitudinal study of personality influences on health. Teachers assessed 963 elementary schoolchildren on traits that formed scales assessing the dimensions of the five-factor (Big Five) model of personality. Smoking, alcohol use, body mass index (BMI), and self-rated health were assessed 40 years later in midlife. Childhood personality traits were significantly associated with all 4 outcomes, and the effects were consistently larger for women than men. For men and women, childhood Conscientiousness was associated with less adult smoking and better adult self-rated health and, for women only, with lower adult BMI. Mediation analyses suggested that the effects of Conscientiousness on self-rated health were partially mediated by smoking and BMI. These findings add to the growing evidence that childhood personality traits predict adult health outcomes and are discussed in terms of future testing of the life span health-behavior model.

What is being assessed and why it matters: The impact of transient error on trait research.

Temporal instability can reflect either true psychological change or transient measurement error, and it is important that trait psychologists be able to distinguish one from the other. The authors report results from large retest studies of Big Five, trait affectivity, and personality disorder measures across time frames (2 months and 2 weeks) over which these constructs should show little or no true change. On average, nearly 25% of the variance in the measures was a product of transient error rather than true change; however, the proportion of error varied widely—but consistently—across measures. In addition, a reexamination of long-term longitudinal data demonstrated that ignoring transient error can lead to inaccurate conclusions. Most notably, a substantial portion of the observed instability in the Big Five and trait affectivity is due to transient error; thus, these traits are even more stable than commonly thought. The present data further suggest that previous reports of differential stability between the Big Five and trait affectivity are due, in part, to differential levels of transient error in measures of these constructs.

A first large cohort study of personality trait stability over the 40 years between elementary school and midlife.

This report provides some initial findings from an investigation of the relations between childhood Big Five personality traits assessed by elementary school teachers and similar traits assessed 40 years later by self-reports at midlife (N = 799). Short-term (1-3 years) test-retest reliabilities were lower (.22-.53) in childhood when personality was developing than they were in adulthood (.70-.79) when personality stability should be at its peak. Stability coefficients across the 40-year interval between the childhood assessment and the 2 measures of adulthood personality were higher for Extraversion (e.g., .29) and Conscientiousness (e.g., .25) than for Openness (e.g., .16), Agreeableness (e.g., .08), and Neuroticism (e.g., .00). Construct continuity between childhood and adulthood was evaluated by canonical analysis and by structural equation modeling and indicated continuity at both a broad, two-dimensional level and at the level of the Big Five. The findings are discussed in relation to A. Caspi, B. W. Roberts, and R. L. Shiner's (2005) principles of rank-order personality stability.

Predicting adult occupational environments from gender and childhood personality traits.

To test aspects of a theory of the role of personality and gender on the development of vocational interests and their subsequent effects on adult occupational choices, the authors of this study examined associations among childhood personality traits, gender, and occupational environments more than 40 years later. Participants (N = 587) were assessed on the Big Five by their teachers when the participants were between 6 and 12 years old. In middle-age (late 40s), the participants reported their occupation. Holland's (1997) RIASEC vocational types (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) were used to characterize the job environments of reported occupations. Childhood Openness/Intellect and Conscientiousness, but no other Big Five traits, were associated with occupational environments. For the most strongly sex-typed work environments, associations with Openness/Intellect were moderated by gender. These findings suggest that the roots of the strongest gender-stereotyping effects in occupations may be found not only in the social factors associated with gender but also in the individual differences of children related to Openness/Intellect.

Can Children Provide Coherent, Stable, and Valid Self-Reports on the Big Five Dimensions? A Longitudinal Study From Ages 5 to 7.

Research on early childhood personality has been scarce. Self-reports of Big Five personality traits were measured longitudinally with the Berkeley Puppet Interview when children were 5, 6, and 7 years of age. For comparative purposes, Big Five self-reports were collected in a sample of college students. The children's self-reports showed levels of consistency and differentiation that approached those of the college age sample. Children's personality self-reports demonstrated significant correlations across the 1- and 2-year longitudinal intervals. Substantial and increasing convergence was found between children's self-reports of Extraversion, Agreeableness, and Conscientiousness and conceptually relevant behavior ratings provided by mothers, fathers, and teachers. Children's self-reports of Neuroticism were unrelated to adults' reports but did predict sadness and anxious behavior observed in the laboratory. The results provide the beginnings of an account of how the Big Five dimensions begin to be salient and emerge as coherent, stable, and valid self-perceptions in childhood.

The relations between parents’ Big Five personality factors and parenting: A meta-analytic review.

To investigate the association between Big Five personality factors and three dimensions of parenting—warmth, behavioral control, and autonomy support—the authors conducted meta-analyses using 5,853 parent–child dyads that were included in 30 studies. Effect sizes were significant and robust across mother and father reports and across assessment methods of parenting (self-report versus observations) but were generally small in magnitude. Higher levels of Extraversion, Agreeableness, Conscientiousness, and Openness and lower levels of Neuroticism were related to more warmth and behavioral control, whereas higher levels of Agreeableness and lower levels of Neuroticism were related to more autonomy support. Several factors moderated the relationship between specific personality dimensions and parenting: child and parental age, reliability of observational assessment of parenting behavior, and study design. Taken together, these results indicate that personality can be seen as an inner resource that affects parenting. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Big Five dimensions and ADHD symptoms: Links between personality traits and clinical symptoms.

Attention-deficit/hyperactivity disorder (ADHD) in adulthood is conceptualized as originating in childhood. Despite considerable theoretical interest, little is known about how ADHD symptoms relate to normal personality traits in adults. In 6 studies, the Big Five personality dimensions were related to ADHD symptoms that adults both recalled from childhood and reported concurrently (total N=1,620). Substantial effects emerged that were replicated across samples. First, the ADHD symptom cluster of inattention-disorganization was substantially related to low Conscientiousness and, to a lesser extent, Neuroticism. Second, ADHD symptom clusters of hyperactivity-impulsivity and oppositional childhood and adult behaviors were associated with low Agreeableness. Results were replicated with self-reports and observer reports of personality in community and clinical samples. Findings support theoretical connections between personality traits and ADHD symptoms.

The nature and structure of correlations among Big Five ratings: The halo-alpha-beta model.

In light of consistently observed correlations among Big Five ratings, the authors developed and tested a model that combined E. L. Thorndike’s (1920) general evaluative bias (halo) model and J. M. Digman’s (1997) higher order personality factors (alpha and beta) model. With 4 multitrait–multimethod analyses, Study 1 revealed moderate convergent validity for alpha and beta across raters, whereas halo was mainly a unique factor for each rater. In Study 2, the authors showed that the halo factor was highly correlated with a validated measure of evaluative biases in self-ratings. Study 3 showed that halo is more strongly correlated with self-ratings of self-esteem than self-ratings of the Big Five, which suggests that halo is not a mere rating bias but actually reflects overly positive self-evaluations. Finally, Study 4 demonstrated that the halo bias in Big Five ratings is stable over short retest intervals. Taken together, the results suggest that the halo-alpa-beta model integrates the main findings in structural analyses of Big Five correlations. Accordingly, halo bias in self-ratings is a reliable and stable bias in individuals’ perceptions of their own attributes. Implications of the present findings for the assessment of Big Five personality traits in monomethod studies are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Linking proactive personality and the Big Five to motivation to learn and development activity.

The authors investigated links between the Big Five, proactive personality, and motivation to learn. Web-based survey data were collected at 2 points in time from 183 employees of a financial services firm. Results showed that proactive personality was, only in part, a composite of Big Five facets, which accounted for 26% of its variance. Structural equation modeling results demonstrated that proactive personality, openness, extraversion, and conscientiousness predicted motivation to learn. In addition, motivation to learn was positively related to objectively assessed development activity. Proactive personality, extraversion, and openness had significant indirect links to development activity. Hierarchical regression results suggested that proactive personality had significant incremental validity in the prediction of motivation to learn over all relevant Big Five facets.

Patterns of stability in adult attachment: An empirical test of two models of continuity and change.

One of the core assumptions of attachment theory is that attachment representations are stable over time. Unfortunately, the data on attachment stability have been ambiguous, and as a result, alternative theoretical perspectives have evolved to explain them. The objective of the present research was to evaluate alternative models of stability by studying adults in 2 intensive longitudinal investigations. Specifically, we assessed attachment representations in 1 sample (N = 203) daily over a 30-day period and in the other sample (N = 388) weekly over a year. Analyses show that the patterns of stability that exist in adult attachment are most consistent with a prototype model—a model assuming that there is a stable factor underlying temporary variations in attachment. Moreover, although the Big Five personality traits exhibited a pattern of stability that was similar to that of attachment, they did not account for the stability observed in attachment.

Dissociations of the night: Individual differences in sleep-related experiences and their relation to dissociation and schizotypy.

The author examined the associations among sleep-related experiences (e.g., hypnagogic hallucinations, nightmares, waking dreams, and lucid-dreams), dissociation, schizotypy, and the Big Five personality traits in 2 large student samples. Confirmatory factor analyses indicated that (a) dissociation and schizotypy are strongly correlated—yet distinguishable—constructs, and (b) the differentiation between them can be enhanced by eliminating detachment/depersonalization items from the dissociation scales. A general measure of sleep experiences was substantially correlated with both schizotypy and dissociation (especially the latter) and more weakly related to the Big Five. In contrast, an index of lucid dreaming was weakly related to all of these other scales. These results suggest that measures of dissociation, schizotypy, and sleep-related experiences all define a common domain characterized by unusual cognitions and perceptions.

How people see others is different from how people see themselves: A replicable pattern across cultures.

Consensus studies from 4 cultures—in Belgium, the Czech Republic, Estonia, and Germany—as well as secondary analyses of self- and observer-reported Revised NEO Personality Inventory (NEO PI-R) data from 29 cultures suggest that there is a cross-culturally replicable pattern of difference between internal and external perspectives for the Big Five personality traits. People see themselves as more neurotic and open to experience compared to how they are seen by other people. External observers generally hold a higher opinion of an individual's conscientiousness than he or she does about him- or herself. As a rule, people think that they have more positive emotions and excitement seeking but much less assertiveness than it seems from the vantage point of an external observer. This cross-culturally replicable disparity between internal and external perspectives was not consistent with predictions based on the actor–observer hypothesis because the size of the disparity was unrelated to the visibility of personality traits. A relatively strong negative correlation (r = ?.53) between the average self-minus-observer profile and social desirability ratings suggests that people in most studied cultures view themselves less favorably than they are perceived by others.

On the temporal stability of personality: Evidence for differential stability and the role of life experiences.

The authors investigated the stability of personality and trait affect in young adults. In Studies 1 and 2, young adults were retested on a Big Five personality measure and a trait affect inventory over a 2.5-year and a 2-month period, respectively. Results from Study 1 point to positive mean-level changes; participants scored higher on Extraversion, Openness, Agreeableness, and Conscientiousness at Time 2. Affectively, participants experienced less negative affect and more positive affect at Time 2. Results from both retests provide clear evidence of differential stability. Affective traits were consistently less stable than the Big Five. Other analyses suggest that life events influence the stability of affective traits more than the Big Five.

A random walk down university avenue: Life paths, life events, and personality trait change at the transition to university life.

This longitudinal study examined the relation between continuity and change in the Big Five personality traits and life events. Approximately 2,000 German students were tracked from high school to university or to vocational training or work, with 3 assessments over 4 years. Life events were reported retrospectively at the 2nd and 3rd assessment. Latent curve analyses were used to assess change in personality traits, revealing 3 main findings. First, mean-level changes in the Big Five factors over the 4 years were in line with the maturity principle, indicating increasing psychological maturity from adolescence to young adulthood. Second, personality development was characterized by substantive individual differences relating to the life path followed; participants on a more vocationally oriented path showed higher increases in conscientiousness and lower increases in agreeableness than their peers at university. Third, initial level and change in the Big Five factors (especially Neuroticism and Extraversion) were linked to the occurrence of aggregated as well as single positive and negative life events. The analyses suggest that individual differences in personality development are associated with life transitions and individual life experiences.

Temperament and personality: Origins and outcomes.

This article reviews how a temperament approach emphasizing biological and developmental processes can integrate constructs from subdisciplines of psychology to further the study of personality. Basic measurement strategies and findings in the investigation of temperament in infancy and childhood are reviewed. These include linkage of temperament dimensions with basic affective–motivational and attentional systems, including positive affect/approach, fear, frustration/anger, and effortful control. Contributions of biological models that may support these processes are then reviewed. Research indicating how a temperament approach can lead researchers of social and personality development to investigate important person–environment interactions is also discussed. Lastly, adult research suggesting links between temperament dispositions and the Big Five personality factors is described. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Big Five factors of personality and replicated predictions of behavior.

Measures of the Big Five factors of personality were used to predict a variety of criterion variables thought to represent behaviors of some social and cultural significance (e.g., alcohol consumption, grade point average). Analyses focused on replicated predictions across 2 independent samples of participants (Ns=276 and 142) with 3 different measures of the Big Five (the NEO Five-Factor Inventory, the Revised NEO Personality Inventory, and the Five-Factor Nonverbal Personality Questionnaire, the latter an experimental nonverbal personality inventory). The results indicated substantial consistency in behavior predictions across the different Big Five assessments. The data are interpreted as supporting both the construct validity of the personality measures used and the role of the Big Five factors as determinants of certain complex behaviors.

Developing a Biodata Measure and Situational Judgment Inventory as Predictors of College Student Performance.

This article describes the development and validation of a biographical data (biodata) measure and situational judgment inventory (SJI) as useful predictors of broadly defined college student performance outcomes. These measures provided incremental validity when considered in combination with standardized college-entrance tests (i.e., SAT/ACT) and a measure of Big Five personality constructs. Racial subgroup mean differences were much smaller on the biodata and SJI measures than on the standardized tests and college grade point average. Female students tended to outperform male students on most predictors and outcomes with the exception of the SAT/ACT. The biodata and SJI measures show promise for student development contexts and for selecting students on a wide range of outcomes with reduced adverse impact.

Birds of a feather don't always fly farthest: Similarity in Big Five personality predicts more negative marital satisfaction trajectories in long-term marriages.

Decades of research suggest that similarity in demographics, values, activities, and attitudes predicts higher marital satisfaction. The present study examined the relationship between similarity in Big Five personality factors and initial levels and 12-year trajectories of marital satisfaction in long-term couples, who were in their 40s and 60s at the beginning of the study. Across the entire sample, greater overall personality similarity predicted more negative slopes in marital satisfaction trajectories. In addition, spousal similarity on Conscientiousness and Extraversion more strongly predicted negative marital satisfaction outcomes among the midlife sample than among the older sample. Results are discussed in terms of the different life tasks faced by young, midlife, and older adults, and the implications of these tasks for the "ingredients" of marital satisfaction.

Personality scale validities increase throughout medical school.

Admissions and personnel decisions rely on stable predictor–criterion relationships. The authors studied the validity of Big Five personality factors and their facets for predicting academic performance in medical school across multiple years, investigating whether criterion-related validities change over time. In this longitudinal investigation, an entire European country’s 1997 cohort of medical students was studied throughout their medical school career (Year 1, N = 627; Year 7, N = 306). Over time, extraversion, openness, and conscientiousness factor and facet scale scores showed increases in operational validity for predicting grade point averages. Although there may not be any advantages to being open and extraverted for early academic performance, these traits gain importance for later academic performance when applied practice increasingly plays a part in the curriculum. Conscientiousness, perhaps more than any other personality trait, appears to be an increasing asset for medical students: Operational validities of conscientiousness increased from .18 to .45. In assessing the utility of personality measures, relying on early criteria might underestimate the predictive value of personality variables. Implications for personality measures to predict work performance are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
