Substance and artifact in the higher-order factors of the Big Five

J. M. Digman (1997) proposed that the Big Five personality traits showed a higher-order structure with 2 factors he labeled alpha and beta. These factors have been alternatively interpreted as heritable components of personality or as artifacts of evaluative bias. Using structural equation modeling, the authors reanalyzed data from a cross-national twin study and from American cross-observer studies and analyzed new multimethod data from a German twin study. In all analyses, artifact models outperformed substance models by root-mean-square error of approximation criteria, but models combining both artifact and substance were slightly better. These findings suggest that the search for the biological basis of personality traits may be more profitably focused on the 5 factors themselves and their specific facets, especially in monomethod studies.     

Personality and mortality risk across the life span: the importance of conscientiousness as a biopsychosocial attribute.

OBJECTIVE: This study addressed whether personality in childhood and personality in adulthood are independent predictors of mortality risk and the extent to which behavioral and other psychosocial factors can explain observed relationships between personality and mortality risk. DESIGN: This was a prospective longitudinal cohort study of 1,253 male and female Californians over 7 decades (1930-2000). Proportional hazards regressions were the principal analyses. MAIN OUTCOME MEASURES: Mortality risk (in the form of relative hazards) was the primary outcome. Additional tests of mediators and moderators ascertained whether associations between personality and mortality risk remained significant when psychosocial and behavioral variables were statistically controlled. RESULTS: The findings, including a new 14-year additional follow-up in old age, revealed that conscientiousness, measured independently in childhood and adulthood, predicted mortality risk across the full life span. The link from childhood remained robust when adult conscientiousness and certain behavioral variables were controlled. Psychosocial and behavioral variables partly explained the adult conscientiousness-longevity association. CONCLUSION: The findings demonstrate the utility and complexity of modern personality concepts in understanding health and point to conscientiousness as a key underexplored area for future biopsychosocial studies.     

Personality out of proportion?

The field of personality assessment has evolved the normative practice of centering scores on their means, evaluating associations among measures with Pearson correlations, and using factor analytic methods to reduce redundancy and provide putative explanatory variables. At least some of these explanatory variables, or factors, have become well-known elements in trait theories of personality structure (e.g., the Five-factor model). Hofstee and Ten Berge (2004/this issue) suggest an alternative set of procedures arising from treating the midpoints of bipolar rating scales as true zero points. These procedures lead to a very different view of personality structure in which one factor provides a nearly sufficient summary of personality judgments. I scrutinize the methodological choices implied by these procedures here. This evaluation leads to the conclusion that Hofstee and Ten Berge provide methods and results that cannot serve to replace normative practice and well-known findings but do provide insight into important questions not typically addressed by personality assessors.     

Validity and Stability of the Youth Psychopathic Traits Inventory in a Nonforensic Sample of Young Adults

Scores were obtained for 103 Subjects on the Sixteen Personality Factor test, Form C; the Edwards Personal Preference Schedule; the Otis Quick Scoring Test, Form G; Raven's Progressive Matrices, Sets A-E; and on 47 handwriting variables. First, personality and intelligence variables, then handwriting variables were factored and rotated, after which factor scores were obtained. Through a regression of handwriting from personality and intelligence factor scores, it was found that 6 of 16 handwriting factors could be predicted by 5 of 10 personality and intelligence factors. These results and their relation to graphology are discussed.

Intention to Migrate: A Psychological Analysis1

A sample of 102 male East Indians intending to immigrate to Canada was compared on several personality and nonpersonality variables with a matched sample of 114 Indians who planned to remain in India. A mail questionnaire procedure was used. Discriminant analyses indicated that personality factors alone accounted for 27% of the variance and that inclusion of nonpersonality factors raised this to 38%. The most important variables separating the groups are occupational satisfaction, sensation seeking, interest in world news, and a locus-of-control component. The findings indicate the sizeable role of personality factors in the decision to migrate and illustrate the utility of a multifaceted approach in understanding complex phenomena such as migration.     

Empirical, theoretical, and practical advantages of the HEXACO model of personality structure.

The authors argue that a new six-dimensional framework for personality structure--the HEXACO model--constitutes a viable alternative to the well-known Big Five or five-factor model. The new model is consistent with the cross-culturally replicated finding of a common six-dimensional structure containing the factors Honesty-Humility (H), Emotionality (E), eExtraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to Experience (O). Also, the HEXACO model predicts several personality phenomena that are not explained within the B5/FFM, including the relations of personality factors with theoretical biologists' constructs of reciprocal and kin altruism and the patterns of sex differences in personality traits. In addition, the HEXACO model accommodates several personality variables that are poorly assimilated within the B5/FFM.     

Toward a Model-Based Approach to the Clinical Assessment of Personality Psychopathology

Recent years have witnessed tremendous growth in the scope and sophistication of statistical methods available to explore the latent structure of psychopathology, involving continuous, discrete, and hybrid latent variables. The availability of such methods has fostered optimism that they can facilitate movement from classification primarily crafted through expert consensus to classification derived from empirically based models of psychopathological variation. The explication of diagnostic constructs with empirically supported structures can then facilitate the development of assessment tools that appropriately characterize these constructs. Our goal in this article is to illustrate how new statistical methods can inform conceptualization of personality psychopathology and therefore its assessment. We use magical thinking as an example, because both theory and earlier empirical work suggested the possibility of discrete aspects to the latent structure of personality psychopathology, particularly forms of psychopathology involving distortions of reality testing, yet other data suggest that personality psychopathology is generally continuous in nature. We directly compared the fit of a variety of latent variable models to magical thinking data from a sample enriched with clinically significant variation in psychotic symptomatology for explanatory purposes. Findings generally suggested a continuous latent variable model best represented magical thinking, but results varied somewhat depending on different indexes of model fit. We discuss the implications of the findings for classification and applied personality assessment. We also highlight some limitations of this type of approach that are illustrated by these data, including the importance of substantive interpretation, in addition to use of model fit indexes, when evaluating competing structural models.     

Personality as modifier of the life event-distress relationship: A longitudinal structural equation model

A structural equation model is presented of the way in which personalityfactors may modify responsiveness to life events and examines this model using data collected in the Groningen Study on a sample of 296 Dutch adults. Three definitions of vulnerability were studied: neuroticism, self-esteem and locus of control. Unlike the Brown/Harris model our model does not assume ‘all or none’ variables but considers exposure to provoking factors, vulnerability and symptom levels as continuous variables. The analysis suggested the following major conclusions. Firstly, previous symptom level was strongly related to current symptom level. The strenght of the relationship was independent from vulnerability. Secondly, the three personality factors did not modify the response to exposure to adversity. Thirdly, locus of control and self-esteem somewhat modified the impact of desirable events. Among high vulnerability Ss (external, low self-esteem) desirable events appeared to reduce symptom level. The implications of these findings for the role of personality in influencing symptom level of Brown/Harris vulnerability model are discussed.     

Taking a person-centered approach to personality: A latent-profile analysis of the HEXACO model of personality

Our study applies a person-centered approach to the HEXACO model of personality using latent profile analysis (LPA). While the traditional variable-centered approach assumes that the relations among variables within a population are homogenous, the person-centered approach identifies subgroups within samples that have similar scores on several variables of interest, in this case, the six factors of personality. Data from two independent samples were collected at a large North American university. The results of LPA revealed five distinct and interpretable profiles that replicated and were found to be consistent across both samples. We discuss how our findings attest to the meaningfulness of personality profiles, and suggest additional ways in which a person-centered approach might be applied in personality research.     

中国人人格结构探索——人格特质六因素假说

研究人格特质背后潜在的结构一直是人格心理学家们工作的一项重要内容,因而存在着人格结构因素（维度）之争;而论证某一人格特质结构的文化普适性（etic）或者文化特殊性（emic）,则成为当今人格特质研究者们工作的一个重要方向,因而存在着彼一人格结构与此一人格结构能否相容之争。文章回顾总结了20多年来有关《中国人个性测量表CPAI》的实证研究结果,提出了一个人格特质“六因素”假说（SFM）,并通过比较中国人和美国人样本在“六因素”结构中的“人际关系性（IR）”和“开放性（O）”因素上的显性/隐性表现,指出人格因素数量及其理论定性之争很可能仅具有方法学意义,对于真正了解人格的本质并非关键。真正找到人类共有的和某一人群特有的人格特质结构的唯一途径,只能是各种文化背景下的人格心理学家超越各自理论、彼此平等接纳、从文化的、乃至遗传的角度共同探索     

On the Construct Validity of Integrity Tests: Individual and Situational Factors as Predictors of Test Performance

Although integrity tests are widely applied in screening job applicants, there is a need for research for examining the construct validity of these tests. In the present study, a theoretical model examining the causes of destructive behavior in organizational settings was used to develop background data measures of individual and situational variables that might be related to integrity test scores. Subsequently, 692 undergraduates were asked to complete these background data scales along with (a) two overt integrity tests – the Reid Report and the Personnel Selection Inventory, and (b) two personality‐based measures – the delinquency and socialization scales of the California Psychological Inventory. When scores of these measures were correlated with and regressed on the background data scales, it was found that relevant individual variables, such as narcissism and power motives, and relevant situational variables, such as alienation and exposure to negative peer groups, were related to scores on both types of integrity tests. However, a stronger pattern of validity evidence was obtained for the personality‐based measures and, in all cases, situational variables were found to be better predictors than individual variables. The implications of these findings for the validity of inferences drawn from overt and personality‐based integrity tests are discussed.     

Five-Factor Model and alcohol outcomes: Mediating and moderating role of alcohol expectancies

The aim of the present study was to examine the relationship between the Five-Factor Model of personality and alcohol expectancies (AEs) with different alcohol outcomes. The sample was composed of 738 participants (63.7% females). Path and regression analyses were performed to test the mediation and moderation effects. The results indicated that Neuroticism was related to alcohol consumption through Positive Alcohol Expectancies, and that Negative Alcohol Expectancies, but also Positive Alcohol Expectancies, partially mediated the relationship of Neuroticism to alcohol-related problems. In addition, Positive Alcohol Expectancies partially mediated the associations of extraversion and low conscientiousness with weekend Standard Drink Units (SDUs), and they completely mediated the associations of these personality variables with alcohol-related problems. Additional direct paths were found from low agreeableness to weekly SDUs and alcohol-related problems; and from low openness to weekend SDUs. Moderation effects of alcohol expectancies on personality and both alcohol use and alcohol-related problems were also found. The present research contributes new evidence on the influence of the five factors of personality on alcohol outcomes, and the mediation/moderation role of alcohol expectancies. These findings can be useful to develop prevention/intervention programmes.     

Psychometric Properties of the HEXACO Personality Inventory

We introduce a personality inventory designed to measure six major dimensions of personality derived from lexical studies of personality structure. The HEXACO Personality Inventory (HEXACO-PI) consists of 24 facet-level personality trait scales that define the six personality factors named Honesty-Humility (H), Emotionality (E), Extraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to Experience (O). In this validation study involving a sample of over 400 respondents, all HEXACO-PI scales showed high internal consistency reliabilities, conformed to the hypothesized six-factor structure, and showed adequate convergent validities with external variables. The HEXACO factor space, and the rotations of factors within that space, are discussed with reference to J. S. Wiggins' work on the circumplex.     

Personality influences in the stability of early (teen-age) marriage in the United States

Previous research indicated that similarities and differences in specific personality factors are associated with differences in marital stability. Most findings were based on assessments of personality after marriage, thus confounding the effects of marriage on personality. The findings reported here relate congruence between spouses’ personality assessed prior to marriage with the status of the marriage three to five years after marriage. Each partner in a group of 72 teenage couples completed the 16PF prior to obtaining approval to marry. These data were examined using intraclass and multivariate analyses. The findings indicate that hypothesized patterns of personality factors differentiated stable from unstable marriages.     

THE STRUCTURE OF CONSCIENTIOUSNESS: AN EMPIRICAL INVESTIGATION BASED ON SEVEN MAJOR PERSONALITY QUESTIONNAIRES

The purpose of this study was to identify the underlying structure of the trait domain of Conscientiousness using scales drawn from 7 major personality inventories. Thirty-six scales conceptually related to Conscientiousness were administered to a large community sample ( N = 737); analyses of those scales revealed a hierarchical structure with 6 factors: industriousness, order, self-control, responsibility, traditionalism, and virtue. All 6 factors demonstrated excellent convergent validity. Three of the 6 factors, industriousness, order, and self-control, showed good discriminant validity. The remaining 3 factors—responsibility, traditionalism and virtue—appear to be interstitial constructs located equally between Conscientiousness and the remaining Big Five dimensions. In addition, the 6 underlying factors had both differential predictive validity and provided incremental validity beyond the general factor of Conscientiousness when used to predict a variety of criterion variables, including work dedication, drug use, and health behaviors.     

Personality and job stress: a comparison of direct effects on parenting

The impact of personality and job characteristics on parental rearing styles was compared in 353 employees. Hypotheses concerning the relationships between personality and job variables were formulated in accordance with findings in past research and the Belsky's model (1984). Structural equation nested models showed that Aggression-hostility, Sociability and job Demand were predictive of Rejection and Emotional Warmth parenting styles, providing support for some of the hypothesized relationships. The findings suggest a well-balanced association of personality variables with both parenting styles: Aggression-Hostility was positively related to Rejection and negatively to Emotional Warmth, whereas Sociability was positively related to Emotional Warmth and negatively related to Rejection. Personality dimensions explained a higher amount of variance in observed parenting styles. However, a model that considered both, personality and job dimensions as antecedent variables of parenting was the best representation of observed data, as both systems play a role in the prediction of parenting behavior.     

The HEXACO model of personality structure and indigenous lexical personality dimensions in Italian,Dutch, and English

We correlated the scales of the HEXACO Personality Inventory (HEXACO-PI) with adjective scale markers of personality factors previously obtained in indigenous lexical studies of personality structure in the Italian, Dutch, and English languages. Self-ratings were obtained from samples of 327 Italian, 161 Dutch, and 214 English-speaking Canadian participants. Results showed that each of the six HEXACO variables—including Honesty–Humility—correlated strongly with its hypothesized six-factor adjective scale counterpart in all three languages. In each case, convergent correlations were substantially stronger than discriminant correlations. Because the HEXACO model was developed without prior knowledge of the indigenous Dutch and English lexical factors, the results suggest that the HEXACO model of personality structure can be extended to the personality lexicons of those languages.     

Personality and Health in the 1980s: Psychosomatic Medicine Revisited?

This special issue is a sign of a resurgence of interest in the role of personality in health not seen since the 1940s and early 1950s when the promises of the psychosomatic approach to health and illness appeared to be the greatest. This new look at personality and health represented by contributions to this special issue attempts to address the limitations of earlier work in psychosomatic medicine by making more explicit efforts to define personality variables precisely, to distinguish these variables from conceptually related psychological constructs, and to embed them in a body of theory and empirical research. This new work also attempts to remedy methodological limitations of earlier work by placing greater emphasis on prospective research and highlighting distinctions between symptom reports, illness behavior, and actual illness. However, the new work and earlier work in psychosomatic medicine share certain working assumptions, for example, a primary emphasis on the relatively direct impact of personality on disease onset, an assumption that personality variables operate in interaction with stressful events, and a frequent emphasis on general susceptibility to disease. Moreover, this new work frequently risks the same methodological pitfalls that limited scientific progress in psychosomatic medicine. We argue that the rapid rise and decline of psychosomatic medicine is most likely to be repeated in research on personality and health in the 1980s if reasonable criteria for considering personality variables a risk factor for disease are not precisely defined, disease endpoints (the dependent variable) are not assessed precisely, personality variables of interest (the independent variable) are not empirically distinguished from other related psychological variables, and complex relationships among risk factors are not taken into account. It is emphasized that models drawn from personality research cannot be transferred unchanged to the health arena without risking false inferences about the role of personality in health.
