Consistency of the adult personality.

Data "… concerning consistency of selected personality variables in the adult personality" were studied in a sample originally composed of 300 engaged couples. "Each of these 600 individuals was assessed with an elaborate battery of techniques including anthropometric measures, blood groupings, a battery of psychological tests, and a 36-variable personality rating scale." Retesting occurred after a lapse of 16 to 18 years. "Our findings indicate that significant changes in the human personality may continue to occur during the years of adulthood. Such changes… are potentially of sufficient magnitude to offer a basis of fact for those who hope for continued psychological growth during the adult years." 20 references.

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.

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.

Age differences in big five behavior averages and variabilities across the adult life span: Moving beyond retrospective, global summary accounts of personality.

In 3 intensive cross-sectional studies, age differences in behavior averages and variabilities were examined. Three questions were posed: Does variability differ among age groups? Does the sizable variability in young adulthood persist throughout the life span? Do past conclusions about trait development, based on trait questionnaires, hold up when actual behavior is examined? Three groups participated: young adults (18–23 years), middle-aged adults (35–55 years), and older adults (65–81 years). In 2 experience-sampling studies, participants reported their current behavior multiple times per day for 1- or 2-week spans. In a 3rd study, participants interacted in standardized laboratory activities on 8 occasions. First, results revealed a sizable amount of intraindividual variability in behavior for all adult groups, with average within-person standard deviations ranging from about half a point to well over 1 point on 6-point scales. Second, older adults were most variable in Openness, whereas young adults were most variable in Agreeableness and Emotional Stability. Third, most specific patterns of maturation-related age differences in actual behavior were more greatly pronounced and differently patterned than those revealed by the trait questionnaire method. When participants interacted in standardized situations, personality differences between young adults and middle-aged adults were larger, and older adults exhibited a more positive personality profile than they exhibited in their everyday lives.

Mechanisms by which childhood personality traits influence adult health status: Educational attainment and healthy behaviors.

Objective: The purpose of this study was to test a life span health behavior model in which educational attainment and health behaviors (eating habits, smoking, and physical activity) were hypothesized as mechanisms to account for relations between teacher ratings of childhood personality traits and self-reported health status at midlife. Design: The model was tested on 1,054 members of the Hawaii Personality and Health cohort, which is a population-based cohort participating in a longitudinal study of personality and health spanning 40 years from childhood to midlife. Outcome: Childhood Agreeableness, Conscientiousness, and Intellect-Imagination influenced adult health status indirectly through educational attainment, healthy eating habits, and smoking. Several direct effects of childhood traits on health behaviors and health status were also observed. Conclusion: The model extends past associations found between personality traits and health behaviors or health status by identifying a life-course pathway based on the health behavior model through which early childhood traits influence adult health status. The additional direct effects of personality traits indicate that health behavior mechanisms may not provide a complete account of relations between personality and health.

Early temperamental and psychophysiological precursors of adult psychopathic personality.

Emerging research on psychopathy in children and adolescents raises the question of whether indicators, such as temperament or psychophysiology, exist very early in life in those with a psychopathic-like personality in adulthood. This study tests the hypothesis that individuals who are more psychopathic in adulthood would be less fearful and inhibited and more stimulation seeking/sociable at age 3 and that they would also show reduced age 3 skin-conductance (SC) responsivity. In a community sample of 335 3-year-olds, behavioral measures of temperament were taken and electrodermal activity was recorded in response to both orienting and aversive tones. R. D. Hare's (1985) Self-Report Psychopathy scale (SRP-II) was administered at follow-up at age 28. Individuals scoring higher on the measure were significantly less fearful and inhibited, were more sociable, and displayed longer SC half-recovery times to aversive stimuli compared with controls at age 3. Contrary to predictions, they also showed increased autonomic arousal and SC orienting. Findings appear to be the first to suggest that a prospective link may exist between temperament and psychophysiology in very young children and psychopathic personality in adulthood.

Determinants of health knowledge: An investigation of age, gender, abilities, personality, and interests.

Ten areas of health knowledge were investigated in 2 studies, 1 of college students (N=169) and 1 of adults from the community (ages 19-70; N=176). Measures assessed knowledge of aging, orthopedic/ dermatological concerns, common illnesses, childhood/early life, serious illnesses, mental health, nutrition, reproduction, safety, and treatment of illness/disease. Significant gender differences favoring women were found for most areas of health knowledge, especially reproduction and early life. Results showed that cognitive ability accounted for the most variance in health knowledge with nonability (personality and interest traits) and demographic variables accounting for smaller but significant amounts of variance across most knowledge domains.

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.

Patterns and sources of adult personality development: Growth curve analyses of the NEO PI-R scales in a longitudinal twin study.

The present study examined the patterns and sources of 10-year stability and change of adult personality assessed by the 5 domains and 30 facets of the Revised NEO Personality Inventory. Phenotypic and biometric analyses were performed on data from 126 identical and 61 fraternal twins from the Bielefeld Longitudinal Study of Adult Twins (BiLSAT). Consistent with previous research, LGM analyses revealed significant mean-level changes in domains and facets suggesting maturation of personality. There were also substantial individual differences in the change trajectories of both domain and facet scales. Correlations between age and trait changes were modest and there were no significant associations between change and gender. Biometric extensions of growth curve models showed that 10-year stability and change of personality were influenced by both genetic as well as environmental factors. Regarding the etiology of change, the analyses uncovered a more complex picture than originally stated, as findings suggest noticeable differences between traits with respect to the magnitude of genetic and environmental effects.

A meta-analysis of normal and disordered personality across the life span.

Debate continues about whether personality, both normal and disordered, can change significantly or is mainly stable across the life span. One issue that receives little attention is the degree to which personality stability coefficients may be influenced by attenuation due to measurement error. The current meta-analysis examines the data from recent research on personality stability, reporting both uncorrected and corrected stability coefficients. Attenuation due to measurement error was found to cause a significant reduction in personality stability coefficients, raising the possibility that some studies may conflate personality change with measurement error. Overall, corrected stability coefficients suggested that the stability of personality across adulthood is high, with only modest change. By contrast, personality during childhood is significantly more changeable. Both normal personality and personality disorders were highly stable across the life span, and patients in therapy experienced no more personality change than did nonpatients. Cross-cultural comparisons suggested relatively similar levels of personality stability cross-culturally, although personality stability among people in South Pacific nations is slightly lower than among those in the United States, Canada, or European nations.

Borderline personality disorder from the perspective of general personality functioning.

The authors extended previous work on the hypothesis that borderline personality disorder (BPD) can be understood as a maladaptive variant of personality traits included within the 5-factor model (FFM) of personality. In each of 3 samples, an empirically derived prototypic FFM borderline profile was correlated with individuals' FFM profiles to yield a similarity score, an FFM borderline index. Results across all samples indicated that the FFM borderline index correlated as highly with existing borderline measures as they correlated with one another, and the FFM borderline index correlated as highly with measures of dysfunction, history of childhood abuse, and parental psychopathology as did traditional measures of BPD. Findings support the hypothesis that BPD is a maladaptive variant of FFM personality traits. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Recalled dream themes and personality.

The manifest content of the dreams of elementary school children were studied in regard to relationship to objective measures of personality. The results suggest that certain kinds of dreams are associated with certain kinds of personality, e.g., dreams involving pleasure gleaned through interpersonal relations seemed to be characteristic of Ss who were described as passive-conformists, inhibited, preferring close interpersonal relations. Characteristic personality traits were found to be associated with dreams that involve pleasure (but not in terms of interpersonal contact) and tension dreams.

The structure of maladaptive personality traits in childhood: A step toward an integrative developmental perspective for DSM-V.

The present study describes the construction of a taxonomy of trait-related symptoms in childhood, the Dimensional Personality Symptom Item Pool (DIPSI), and examines the replicability of the taxonomy's higher order structure across maternal ratings of referred (N = 205) and nonreferred (N = 242) children and self-ratings of adolescents (N = 453). The DIPSI's 4 higher order factors--that is, Emotional Instability, Disagreeableness, Introversion, and Compulsivity--showed clear correspondence with the dimensions of personality pathology found in adulthood (Dimensional Assessment of Personality Pathology-Basic Questionnaire; W. J. Livesley, 1990; Schedule for Nonadaptive and Adaptive Personality; L. A. Clark, 1993). These 4 factors can be further organized into 2 superfactors, representing Internalizing and Externalizing Traits, demonstrating empirical and conceptual relationships with psychopathology models in childhood and adulthood. The implications for the assessment and conceptualization of early trait pathology are discussed in the context of an integrative developmental perspective on the construction of the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition.

Personality and obesity across the adult life span.

Personality traits contribute to health outcomes, in part through their association with major controllable risk factors, such as obesity. Body weight, in turn, reflects our behaviors and lifestyle and contributes to the way we perceive ourselves and others. In this study, the authors use data from a large (N = 1,988) longitudinal study that spanned more than 50 years to examine how personality traits are associated with multiple measures of adiposity and with fluctuations in body mass index (BMI). Using 14,531 anthropometric assessments, the authors modeled the trajectory of BMI across adulthood and tested whether personality predicted its rate of change. Measured concurrently, participants higher on Neuroticism or Extraversion or lower on Conscientiousness had higher BMI; these associations replicated across body fat, waist, and hip circumference. The strongest association was found for the impulsivity facet: Participants who scored in the top 10% of impulsivity weighed, on average, 11Kg more than those in the bottom 10%. Longitudinally, high Neuroticism and low Conscientiousness, and the facets of these traits related to difficulty with impulse control, were associated with weight fluctuations, measured as the variability in weight over time. Finally, low Agreeableness and impulsivity-related traits predicted a greater increase in BMI across the adult life span. BMI was mostly unrelated to change in personality traits. Personality traits are defined by cognitive, emotional, and behavioral patterns that likely contribute to unhealthy weight and difficulties with weight management. Such associations may elucidate the role of personality traits in disease progression and may help to design more effective interventions.

Audience stress, personality, and speech.

"Forty-eight children, aged 10 to 12 years, told two stories to the experimenter alone and two to an audience of six adults… . Almost every subject told a longer story in the private compared to the audience situation. Highly exhibitionistic children were least influenced in this respect whereas self-conscious children reduced the length of their stories drastically before the six observers. Children who were both highly exhibitionistic and self-conscious made the most speech errors." From Psyc Abstracts 36:02:2FC69L. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Five-factor personality traits and subjective health among caregivers: The role of caregiver strain and self-efficacy.

This study examined the association among caregivers' five-factor personality traits and subjective health with particular emphasis on the role of two theoretically implicated mediators: multi-domain self-efficacy and caregiver strain. The sample comprised 536 informal caregivers (mean age = 62.9 years, SD = 19.9, 72% female, 98% White) of community-dwelling older adults with multiple functional impairments. Both physical health and mental health were negatively associated with neuroticism and positively associated with extraversion and conscientiousness. Agreeableness and openness were associated with better subjective mental health and physical health, respectively. Multiple mediation analyses indicated that self-efficacy mediated all observed associations between personality and subjective health, whereas caregiver strain selectively mediated the associations of neuroticism and agreeableness with mental health.

Middle childhood and adolescent contextual and personal predictors of adult educational and occupational outcomes: A mediational model in two countries.

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 Jyv?skyl? Longitudinal Study of Personality and Social Development, a study of 369 eight-year-olds in Jyv?skyl?, Finland, that began in 1968. Both samples were followed up during adolescence and early and middle adulthood. Structural modeling analyses revealed that in both countries, for both genders, children's age 8 cognitive-academic functioning and their parents' occupational status had independent positive long-term effects on the children's adult occupational attainment, even after other childhood and adolescent personal variables were controlled for. Further, childhood and adolescent aggressive behavior negatively affected educational status in early adulthood, which in turn predicted lower occupational status in middle adulthood.

Early mothering experience and personality change.

This study examined the context of the early mothering experience and how that experience was related to personality change in 48 members of a longitudinal sample of women from age 21 (in 1958 or 1960), before any of them were married, to age 27 (in 1963 or 1964). Early motherhood was analyzed in terms of (a) how positively the woman described her experience and (b) how willing and able she was to maintain the full-time commitment considered necessary in the early 1960s. Path analyses showed that these two dimensions had somewhat different interrelations with mother's personality, the marriage, and husband's personality and participation as a father. However, both dimensions were related to relative increase in ego-resiliency and to relative decrease in feelings of vulnerability between ages 21 and 27, even when family and work variables were taken into account.

Using theory to evaluate personality and job-performance relations: A socioanalytic perspective.

The authors used socioanalytic theory to understand individual differences in people's performance at work. Specifically, if predictors and criteria are aligned by using theory, then the meta-analytic validity of personality measures exceeds that of atheoretical approaches. As performance assessment moved from general to specific job criteria, all Big Five personality dimensions more precisely predicted relevant criterion variables, with estimated true validities of .43 (Emotional Stability), .35 (Extraversion-Ambition), .34 (Agreeableness), .36 (Conscientiousness), and .34 (Intellect-Openness to Experience).

Long-term outcome from childhood traumatic brain injury: Intellectual ability, personality, and quality of life.

Objective: Only a handful of studies have attempted to explore very long-term outcomes from childhood traumatic brain injury (TBI). These studies have generally failed to fully consider the impact of injury severity or employ measures sensitive to the survivor's day-to-day function. This study examined outcomes in adulthood, with a focus on functional abilities including education, employment, and quality of life (QOL), and employed predictors including injury severity, age at injury, socioeconomic factors, intelligence, and personality. Method: The study was retrospective and cross-sectional and included 50 adult survivors of child TBI (31 males), aged 19–30 years at evaluation (M = 24.2, SD = 3.6), with injury on average 13.3 years prior to evaluation. Participants were divided according to injury severity—mild (n = 20), moderate (n = 12), and severe (n = 18)—completed an intellectual evaluation and questionnaires regarding educational and employment status, personality, and quality of life. Results: Intellectual and personality measures indicated good outcomes, with mean scores for all groups in the average range and few severity-based findings. In contrast, those with more severe TBI were more likely to have educational and employment problems. QOL was significantly reduced in the context of severe insult, with lower IQ and personality factors most predictive of outcome in this domain. Mild and moderate TBI were generally more benign. Conclusions: Findings suggest that, while TBI is a lifelong problem, its impact is most dramatic in the domain of QOL, where a complex interaction occurs between injury factors, cognition, and personality.
