Correspondence between personality trait ratings and behavioral events

To investigate the validity of the trait, Energetic, two studies were conducted in which trait ratings of Energetic and objective measures of performance were recorded. The first study used naive raters (N= 55) who observed pairs of subjects perform in a laboratory setting. There was 84% agreement (p < .001) among the raters as to which person was more Energetic, and people rated as more Energetic performed more energetically on the objectively measured tasks (p < .001). The second study used peer ratings of Energetic and objective measures of energetic behavior in a laboratory setting. There was high agreement among the peers in ratings of Energetic, r = .95 (N = 30) and r = .93 (N = 31) for two groups. Nine men from the upper-quartile and nine men from the lower-quartile of the Energetic scores were tested in the laboratory and were given a structured interview regarding their physical activities. The correlation between peer ratings and laboratory performance was .56 and between peer ratings and the interview data, .64. The results support the position that trait ratings can be valid indicators of regularities in behavior. The procedures used in these studies could be a generally useful model for investigations of the validity of trait ratings.     

Temporal course and structural relationships among dimensions of temperament and DSM-IV anxiety and mood disorder constructs

The temporal stability and directional relations among dimensions of temperament (e.g., neuroticism) and selected Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) disorder constructs (depression, generalized anxiety disorder, social phobia) were examined in 606 outpatients with anxiety and mood disorders, assessed on 3 occasions over a 2-year period. Neuroticism/behavioral inhibition (N/BI) and behavioral activation/positive affect (BA/P) accounted for the cross-sectional covariance of the DSM-IV constructs. Although N/BI evidenced the most change of the constructs examined, initial levels of N/BI predicted less improvement in 2 of the 3 disorder constructs. Unlike the DSM-IV disorder constructs, the temporal stability of N/BI increased as a function of initial severity. Moreover, N/BI explained all the temporal covariation of the DSM-IV disorder constructs. The results are discussed in regard to conceptual models of temperament that define N/BI and BA/P as higher order dimensions accounting for the course and covariation of emotional disorder psychopathology.     

Psychopathy and the DSM-IV criteria for antisocial personality disorder

The Axis II Work Group of the Task Force on DSM-IV has expressed concern that antisocial personality disorder (APD) criteria are too long and cumbersome and that they focus on antisocial behaviors rather than personality traits central to traditional conceptions of psychopathy and to international criteria. We describe an alternative to the approach taken in the rev. 3rd ed. of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R; American Psychiatric Association, 1987), namely, the revised Psychopathy Checklist. We also discuss the multisite APD field trials designed to evaluate and compare four criteria sets: the DSM-III-R criteria, a shortened list of these criteria, the criteria for dyssocial personality disorder from the 10th ed. of the International Classification of Diseases (World Health Organization, 1990), and a 10-item criteria set for psychopathic personality disorder derived from the revised Psychopathy Checklist.     

Perceived dysfunction of male-typed and female-typed DSM-IV personality disorder criteria

To determine whether female-typed personality disorders are associated with a different pattern of dysfunction than male-typed disorders, lay judges (N = 216) estimated the amount of social impairment, occupational impairment, and personal distress related to symptoms of personality disorders. Results for both the subset of six disorders originally rated by clinician judges in the research of Funtowicz and Widiger (1999) and for a larger set of nine disorders revealed a pattern originally reported by Funtowicz and Widiger where female-typed disorders were associated with relatively higher ratings of personal distress, whereas male-typed disorders were associated with relatively higher ratings of social (and sometimes occupational) impairment. Findings are discussed with respect to the emphasis of different forms of dysfunction for male- and female-typed disorders, lay versus clinician judgments, and directions for future research.     

Opinions of personality disorder experts regarding the DSM-IV personality disorders classification system

OBJECTIVE: To survey the opinions of personality disorder (PD) experts on possible revisions in the classification system for PDs in the DSM-V. METHOD: Four hundred members of two international associations, the Association for Research on Personality Disorders, and the International Society for the Study of Personality Disorders, were asked to take a 78-item web survey. RESULTS: Of the experts who completed the survey (N = 96), 74% felt that the DSM-IV's categorical system of PD diagnosis should be replaced. Eighty percent felt that PDs are better conceived of as personality dimensions or illness spectra, than as categories. The most frequently endorsed alternative system for PDs was a mixed system of categories and dimensions. Most experts preferred the PDs to remain on Axis II. Only 31.3% wanted the term, "Borderline Personality Disorder," retained in the DSM-V. CONCLUSIONS: A clear majority of the PD experts were dissatisfied with the current diagnostic system for PDs.     

Mindfulness, Big Five personality, and affect: A meta-analysis

Mindfulness is purposefully and nonjudgmentally paying attention to the present moment. The primary purpose of this study is to provide a more precise empirical estimate of the relationship between mindfulness and the Big Five personality traits as well as trait affect. Current research results present inconsistent or highly variable estimates of these relationships. Meta-analysis was used to synthesize findings from 32 samples in 29 studies. Results indicate that, although all of the traits display appreciable relationships with mindfulness, the strongest relationships are found with neuroticism, negative affect, and conscientiousness. Conscientiousness, in particular, is often ignored by mindfulness researchers; results here indicate it deserves stronger consideration. Although the results provide a clearer picture of how mindfulness relates to these traits, they also highlight the need to ensure an appropriate conceptualization and measurement of mindfulness.     

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.

Genetic and environmental contributions to the co-occurrence of depressive personality disorder and DSM-IV personality disorders

One of the main controversies with regard to depressive personality disorder (DPD) concerns the co-occurrence with the established DSM-IV personality disorders (PDs). The main aim of this study was to examine to what extent DPD and the DSM-IV PDs share genetic and environmental risk factors, using multivariate twin modeling. The DSM-IV Structured Interview for Personality was applied to 2,794 young adult twins. Paranoid PD from Cluster A, borderline PD from Cluster B, and all three PDs from Cluster C were independently and significantly associated with DPD in multiple regression analysis. The genetic correlations between DPD and the other PDs were strong (.53-.83), while the environmental correlations were moderate (.36-.40). Close to 50% of the total variance in DPD was disorder specific. However, only 5% was due to disorder-specific genetic factors, indicating that a substantial part of the genetic vulnerability to DPD also increases the vulnerability to other PDs.     

The Big Five personality traits, learning styles, and academic achievement

Personality and learning styles are both likely to play significant roles in influencing academic achievement. College students (308 undergraduates) completed the Five Factor Inventory and the Inventory of Learning Processes and reported their grade point average. Two of the Big Five traits, conscientiousness and agreeableness, were positively related with all four learning styles (synthesis analysis, methodical study, fact retention, and elaborative processing), whereas neuroticism was negatively related with all four learning styles. In addition, extraversion and openness were positively related with elaborative processing. The Big Five together explained 14% of the variance in grade point average (GPA), and learning styles explained an additional 3%, suggesting that both personality traits and learning styles contribute to academic performance. Further, the relationship between openness and GPA was mediated by reflective learning styles (synthesis-analysis and elaborative processing). These latter results suggest that being intellectually curious fully enhances academic performance when students combine this scholarly interest with thoughtful information processing. Implications of these results are discussed in the context of teaching techniques and curriculum design.     

Confirmatory factor analyses of DSM-IV Cluster C personality disorder criteria

Notwithstanding its research and clinical relevance, the dimensionality and validity of the DSM-IV avoidant, dependent, and obsessive-compulsive personality disorders (PDs) criteria is still a largely unexplored topic. The aim of this study was to test the factor structure for DSM-IV Cluster C PD criteria in a sample of 641 consecutively admitted outpatients. Factor analysis results suggested that avoidant, dependent, and obsessive-compulsive PDs share a common latent dimension, and supported the three-factor structure of both observer and self-report ratings of DSM-IV Cluster C PD criteria. The pattern of factor loadings, however, was different from the one expected according to the DSM-IV classification.     

The validity of DSM-IV passive-aggressive (negativistic) personality disorder

Passive-Aggressive (Negativistic) Personality Disorder (NEGPD), listed in Appendix B of the DSM-IV, is not an officially recognized personality disorder. Its future as a discrete disorder is uncertain (Widiger, 2003). Yet, NEGPD occupies a role in some theoretical formulations of personality pathology (Millon & Davis, 1996), and many clinicians believe that passive-aggressive traits are not adequately represented by other PDs (Westen, 1997). In this study, 1158 psychiatric outpatients were assessed for Axis I and Axis II disorders. Thirty-five (3.02%) met criteria for NEGPD. Participants with NEGPD did not differ significantly from those without NEGPD on demographic variables. The internal consistency of the DSM-IV's seven NEGPD items was 0.50. Corrected item- total correlations for the 7 criteria averaged 0.27. Participants with NEGPD had higher rates of lifetime anxiety disorders, and almost 90% had an additional PD. An exploratory factor analysis suggested a two- factor solution that accounted for 43.4% of the variance. The first factor reflected the belief that life is unfair, while the second factor seemed to reflect modes of anger expression. A confirmatory factor analysis showed that the two-factor model fit the data better than a unidimensional model. We discuss implications of these results for the future of the NEGPD diagnosis.     

Body image and personality among British men: Associations between the Big Five personality domains,drive for muscularity,and body appreciation

The present study examined associations between the Big Five personality domains and measures of men's body image. A total of 509 men from the community in London, UK, completed measures of drive for muscularity, body appreciation, the Big Five domains, and subjective social status, and provided their demographic details. The results of a hierarchical regression showed that, once the effects of participant body mass index (BMI) and subjective social status had been accounted for, men's drive for muscularity was significantly predicted by Neuroticism (β = .29). In addition, taking into account the effects of BMI and subjective social status, men's body appreciation was significantly predicted by Neuroticism (β = −.35) and Extraversion (β = .12). These findings highlight potential avenues for the development of intervention approaches based on the relationship between the Big Five personality traits and body image.     

Nonverbal assessment of the Big Five personality factors

The Nonverbal Personality Questionnaire (NPQ) is an experimental, structured, nonverbal measure of 16 personality traits. Its items lack verbal content and, therefore, the inventory is useful for cross‐cultural research. Our goal is this research was to select a subset of the NPQ items to form a new nonverbal questionnaire based on the Five‐Factor Model of personality. We describe the construction of the Five‐Factor Nonverbal Personality Questionnaire (FF‐NPQ), and present data on its psychometric properties. These data include scale internal consistencies, intercorrelations, convergences with verbal measures of the Big Five factors, discriminant validity correlations, correlations with peer ratings, and ability to predict socially important behaviour criteria such as smoking and alcohol consumption. In a second study, we report on the psychometric properties of the FF‐NPQ in an independent sample of respondents from seven different countries. The utility of the new nonverbal inventory for cross‐cultural research is discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

The Big Five personality traits,Big Two metatraits and social media: A meta-analysis

This article reported a meta-analysis of the relationships between social network site use and the Big Five (neuroticism, extraversion, openness, agreeableness, and conscientiousness) as well as the Big Two (plasticity and stability) personality meta-traits. A random effect meta-analysis model was used to calculate the meta-results of Big Five. Extraversion and openness were the strongest predictor of SNS activities (e.g. gaming, SNS interaction, etc.), while conscientiousness, neuroticism, and agreeableness only correlated with a few of the SNS activities. A meta-analytical structural equation model further demonstrated that plasticity was positively correlated with SNS activities, whereas stability was a negative predictor. Practical implications for social media industry and users were discussed.     

The relationship between the entrepreneurial personality and the Big Five personality traits

Although meta-analyses show that the Big Five personality traits predict business intention, creation, and success (Brandstätter, 2011), they also indicate that narrow personality traits, such as innovativeness, predict these outcomes better than broad traits, such as Conscientiousness and Extraversion (Rauch & Frese, 2007). The current study extends previous research to examine the relationship between the Big Five and a wider range of entrepreneurial outcomes (e.g. founding charitable organisations, organising events, and changing organisational practices). Additionally, it establishes the incremental validity of a narrow measure of entrepreneurial personality over the Big Five (META, Ahmetoglu, Leutner, & Chamorro-Premuic, 2011). Both the Big Five and META significantly predict various forms of entrepreneurial success, though META does so more consistently. This suggests that narrow personality traits have incremental validity in predicting entrepreneurial success vis-à-vis the Big Five. Theoretical and applied implications are discussed.     

On friendship development and the Big Five personality traits

In this paper, we argue that friendship should receive more attention in social/personality research. Here, we focus on our area of expertise, personality traits, and review the literature on how personality traits influence friendship formation, maintenance, and dissolution. Specifically, we examine how personality traits of the actor and partner influence friendship development (i.e., who is more likely to initiate and end friendships, and who is more likely to be the target of friendship initiation and termination). We also discuss dyadic effects, such as personality similarity, on friendship development. Throughout this review, we draw on the literature on personality and romantic relationships to identify the most important gaps in the literature on personality and friendships. Our review suggests that agreeableness has the most consistent effects on both romantic relationships and friendships, followed by neuroticism. Extraversion, conscientiousness, and openness to experience have all been shown to influence relationship development, but their effects are inconsistent. We end with a call for more research on friendship beyond the role of personality traits and suggestions for specific future directions.     

Big Five personality traits and allostatic load in midlife

Objective: To examine the cross-sectional associations of Big Five personality traits with midlife allostatic load, including the role of sex, socio-demographic factors and health-related behaviours.

Design: Cross-sectional analyses of 5512 members of the Copenhagen Aging and Midlife Biobank, aged 49–63 years, 69% men.

Main outcome measure: Allostatic load (AL) based on 14 biomarkers representing the inflammatory, cardiovascular and metabolic system.

Results: Due to significant sex?×?trait interactions, analyses were stratified by sex. Openness and Conscientiousness were inversely associated with AL in both sexes, and Extraversion was positively associated with AL in men. Adjusting for socio-demographic factors significantly attenuated the association of Openness in both sexes and of Extraversion in men, for whom the inverse association of Agreeableness with AL was strengthened. Further adjusting for health-related behaviours, the Conscientiousness-AL association was attenuated but remained significant, and Agreeableness remained significantly associated with AL in men.

Conclusion: Results imply that higher levels of Agreeableness (in men) and Conscientiousness are associated with lower levels of AL above and beyond socio-demographic factors and health-related behaviours. The study further contributes by demonstrating the relevance of sex?×?trait and trait?×?trait interactions in the personality-health literature.
