Universal features of personality traits from the observer's perspective: Data from 50 Cultures

Abstract: To test hypotheses about the universality of personality traits, college students in 50 cultures identified an adult or college-aged man or woman whom they knew well and rated the 11,985 targets using the 3rd-person version of the Revised NEO Personality Inventory. Factor analyses within cultures showed that the normative American self-report structure was clearly replicated in most cultures and was recognizable in all. Sex differences replicated earlier self-report results, with the most pronounced differences in Western cultures. Cross-sectional age differences for 3 factors followed the pattern identified in self-reports, with moderate rates of change during college age and slower changes after age 40. With a few exceptions, these data support the hypothesis that features of personality traits are common to all human groups.

Personality profiles of cultures: aggregate personality traits.

Abstract: Personality profiles of cultures can be operationalized as the mean trait levels of culture members. College students from 51 cultures rated an individual from their country whom they knew well (N=12,156). Aggregate scores on Revised NEO Personality Inventory (NEO-PI-R) scales generalized across age and sex groups, approximated the individual-level 5-factor model, and correlated with aggregate self-report personality scores and other culture-level variables. Results were not attributable to national differences in economic development or to acquiescence. Geographical differences in scale variances and mean levels were replicated, with Europeans and Americans generally scoring higher in Extraversion than Asians and Africans. Findings support the rough scalar equivalence of NEO-PI-R factors and facets across cultures and suggest that aggregate personality profiles provide insight into cultural differences.

The NEO-PI-3: a more readable revised NEO Personality Inventory.

Abstract: Use of the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992) in adolescent samples has shown that a few respondents have difficulty with a subset of items. We identified 30 items that were not understood by at least 2% of adolescent respondents and 18 additional items with low item-total correlations, and we wrote 2 trial replacement items for each. We used self-report and observer rating data from 500 respondents aged 14 to 20 to select replacement items. The modified instrument retained the intended factor structure and showed slightly better internal consistency, cross-observer agreement, and readability (Flesch-Kincaid grade level = 5.3). The NEO-PI-3 appears to be useful in high school and college samples and may have wider applicability to adults as well.

Domain and facet personality predictors of all-cause mortality among Medicare patients aged 65 to 100.

Abstract: Objectives: Our objectives were to test whether Conscientiousness, the other 4 domains of the Five-Factor Model, and their facets predicted mortality in older, frail individuals. Methods: Controlling for demographic and health measures, we used Cox regression to test whether the NEO Five-Factor Inventory (NEO-FFI) Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness domains predicted all-cause mortality over 5 years in 1076 65- to 100-year-old participants who took part in a Medicare Demonstration study. Supplementary analyses on 597 participants aged 66 to 102 who were reassessed 2 years later were conducted to determine whether any of the Revised NEO Personality Inventory (NEO-PI-R) facets were related to mortality. Results: When personality domains were treated as continuous variables, NEO-FFI Neuroticism and Agreeableness were significant protective factors. When personality domains were trichotomized, NEO-FFI Conscientiousness was a protective factor. In a third analysis, Agreeableness was not a significant predictor in a model that included the continuous Neuroticism and trichotomized Conscientiousness variables. Analysis of the NEO-PI-R Neuroticism, Agreeableness, and Conscientiousness factors showed that Agreeableness and Conscientiousness were protective and that there was a trend for a similar effect of Neuroticism. Facet-level analyses revealed that the Impulsiveness, Straightforwardness, and Self-Discipline facets of Neuroticism, Agreeableness, and Conscientiousness, respectively, were prospectively related to greater survival over a 3-year interval. Conclusion: The effects of Neuroticism and Agreeableness on mortality are inconsistent across previous studies. This study indicates that, in a sample of older, frail participants, high Neuroticism and Agreeableness scores are protective and that more specific effects are primarily the result of the Impulsiveness and Straightforwardness facet scales. The Conscientiousness findings are consistent with those in earlier studies and demonstrate the importance of the Self-Discipline facet.

Age Trends and Age Norms for the NEO Personality Inventory-3 in Adolescents and Adults:

Abstract: The NEO Personality Inventory-3 (NEO-PI-3) is a modification of the Revised NEO Personality Inventory (NEO-PI-R) designed to be more understandable to adolescents. Data from adults aged 21 to 91 showed that the NEO-PI-3 also functions as well or better than the NEO-PI-R in adults. Age trends from combined adolescent (n = 500) and adult (n = 635) samples confirmed previous cross-sectional findings and demonstrated the importance of studying age changes especially at the facet level and during the decade of the 20s. Normative data for self-report and observer rating forms for adolescents, younger and older adults, and all adults are discussed, as well as for a combined-age group. It is argued that combined-age norms may be most appropriate for depicting the personality scores of individuals, but the utility for some purposes of within-age group scores is also acknowledged.

DSM-IV Personality Disorders and the Five-Factor Model of Personality: A Multi-Method Examination of Domain--and Facet-Level Predictions.

Abstract: The personality disorder classification system (Axis II) in the various versions of the Diagnostic and Statistical Manuals of Mental Disorders (DSM) has been the target of repeated criticism, with conceptual analysis and empirical evidence documenting its flaws. In response, many have proposed alternative approaches for the assessment of personality psychopathology, including the application of the Five-Factor Model of personality (FFM). Many remain sceptical, however, as to whether domain and facet traits from a model of general personality functioning can be successfully applied to clinical patients with personality disorders (PDs). In this study, with a sample of psychiatric patients (n ¼115), personality disorder symptoms corresponding to each of the 10 PDs were successfully predicted by the facet and domain traits of the FFM, as measured by a semi-structured interview, the Structured Interview for the Five Factor Model (SIFFM; Trull & Widiger, 1997) and a self-report questionnaire, the Revised NEO Personality Inventory (NEO PI-R; Costa and McCrae, 1992). These results provide support for the perspective that personality psychopathology can be captured by general personality dimensions. The FFM has the potential to provide a valid and scientifically sound framework from which to assess personality psychopathology, in a way that covers most of the domains conceptualized in DSM while transcending the limitations of the current categorical approach to these disorders.

Structural and Mean-Level Analyses of the Five-Factor Model and Locus of Control: Further Evidence From Africa

Abstract: This study examines the Five-Factor Model of personality and locus of control in French-speaking samples in Burkina Faso (N = 470) and Switzerland (Ns = 1,090, 361), using the Revised NEO Personality Inventory (NEO-PI-R) and Levenson’s Internality, Powerful others, and Chance (IPC) scales. Alpha reliabilities were consistently lower in Burkina Faso, but the factor structure of the NEO-PI-R was replicated in both cultures. The intended three-factor structure of the IPC could not be replicated, although a two-factor solution was replicable across the two samples. Although scalar equivalence has not been demonstrated, mean-level comparisons showed the hypothesized effects for most of the five factors and locus of control; Burkinabe scored higher in Neuroticism than anticipated. Findings from this African sample generally replicate earlier results from Asian and Western cultures and are consistent with a biologically based theory of personality.

Socially desirable responding and the factorial stability of the NEO PI-R.

Abstract: The goal of the present investigation is to compare the factor structure of the revised NEO Personality Inventory (NEO PI-R; P. T. Costa & R. R. McCrae, 1992) in samples of respondents differentially motivated to respond in a socially desirable manner. In the French sample, the authors compared the NEO PI-R structure of job applicants (N = 12,631) subgrouped by relative degree of socially desirable responding with that of a normative sample (N = 801), In the Belgian sample, the authors compared the NEO Pl-R structure in naturally occurring groups, including job applicants (N = 3,028), individuals receiving career counseling (N = 221), and a normative sample (N = 549). Results indicate that the NEO Pl-R factor structure remained stable across all samples.

The impact of personality on symptom expression in obsessive-compulsive disorder.

Abstract: Previous research conducted on the five-factor model of personality (FFM) in obsessive-compulsive disorder (OCD) has demonstrated that community and clinical participants score significantly higher than controls on the domains and facets of neuroticism and extraversion and selective facets of agreeableness and conscientiousness. However, studies have yet to examine the extent to which personality traits, as assessed by the FFM, are associated with the specific symptoms of OCD. The purpose of this study was to examine further the personality predictors of obsessive-compulsive symptoms in clinical participants using the facets of the FFM. Patients with a DSM-IV diagnosis of OCD (N = 56) completed the Revised NEO Personality Inventory, the Yale Brown Obsession Compulsion Scale, and the Beck Depression Inventory. Lower scores on openness to ideas were uniquely associated with greater obsession severity, whereas lower openness to actions was uniquely associated with greater compulsive severity. In contrast with past research that has emphasized the association between neuroticism and extraversion and dimensionally rated obsessive-compulsive symptoms, this study demonstrates the specific associations between selective facet traits of openness and clinical obsessions and compulsions. Whereas tendencies toward negative affectivity may confer a nonspecific vulnerability to the development of OCD, facets of openness may impact on the particular expression and severity of obsessive-compulsive symptoms.

Applying the Five-Factor Model of Personality to the Exploration of the Construct of Risk-Taking in Obsessive-Compulsive Disorder

Abstract: Although there has been a long interest in the personality traits associated with obsessive-compulsive disorder (OCD), few studies have examined differences on normal, dimensional personality traits for individuals with OCD compared with other clinical disorders. The purpose of this study was to replicate and extend upon the work of Rector et al. (2002) who found unique associations between OCD and trait domains and facets of the five-factor model of personality (FFM) when compared with a clinical sample of depressed individuals. The current study compared individuals with a current diagnosis of OCD (n = 21) with individuals with a current diagnosis of anxiety or depression but no OCD symptoms (n = 39) on the Revised NEO Personality Inventory (NEO PI-R Form S). Of particular interest was whether individuals with OCD would differ from other clinically anxious/depressed individuals on the actions facet of the FFM, as this facet is known to be related to harm and risk avoidance, and previous research suggests specific relationships between these forms of avoidance and OCD. Individuals with OCD were found to have lower scores on the actions, competence and self-discipline facets. These results add further support to previous research that suggests unique associations between trait domains and facets of the FFM and OCD.

Serotonin 2A receptor gene polymorphism and personality traits: no evidence for significant association.

Abstract: A number of studies have observed associations between the serotonin 2A (5-HT2A) receptor and mental disorders. Here, we investigated correlations between polymorphisms (-1438G/A and 102T/C) of the 5-HT2A gene and personality traits in healthy Japanese volunteers (n = 239). The personality traits were evaluated using the Revised NEO Personality Inventory (NEO PI-R). The -1438G/A and 102T/C were in complete linkage disequilibrium. There was a tendency for associations between the genotype and the scores for Agreeableness, Conscientiousness and Neuroticism of the NEO PI-R (P = 0.028, 0.039 and 0.062, respectively; analysis of variance, uncorrected for multiple testing). Subjects with the A/A of -1438G/A (or T/T of 102T/C) appeared to be lower in Neuroticism and higher in Conscientiousness than the rest of the subjects. However, the results were statistically non-significant after Bonferroni's correction for multiple testing of the five scales of the NEO PI-R. Thus, the present study provided no evidence for statistically significant associations between the 5-HT2A polymorphisms and the personality traits.

A dimensional approach to personality in atypical depression.

Abstract: The current study addresses the relationship of personality and atypical depression using the Five-Factor Model (FFM), a dimensional approach to personality. The aim of the study was to help clarify which personality traits are more characteristic of atypical depression than of other depressive subtypes. Outpatients ( n = 160) with non-psychotic major depression were characterized as having atypical ( n = 26), or non-atypical depression ( n = 134) based on DSM-IV criteria. To limit the effect of state depression, personality was assessed after subjects received a minimum of 14 weeks of antidepressant treatment. The Revised NEO Personality Inventory, which generates data based on the FFM, was the primary assessment measure. Post-treatment, relative to the non-atypical comparison group, the atypical group had significantly higher scores on the dimension of Neuroticism, the facets of Impulsivity and Anger–Hostility, and a significantly lower score on the facet of Deliberation. In sum, the FFM provides a new understanding of which unique personality characteristics may be associated with atypical depression.

Personality characteristics of asthma patients.

Abstract: INTRODUCTION Asthma, similarly to other chronic conditions, is strongly influenced by psychological factors. Previous studies have not established the personality characteristics of adult asthma patients as compared to non-patients. OBJECTIVES To study the psychological characteristics of adult asthma patients in comparison to a pattern drawn up for the Portuguese population. To study the relationships between the personality and the severity and duration of the disease. METHODS Outpatients of the Immunallergology and Pulmonology units of the Sao Joao Hospital suffering from asthma responded to the Revised NEO Personality Inventory (NEO-PI-R). Patients with co-morbidity factors were not excluded. The doctor who attended them classified the severity of the asthma according to the Global Initiative for Asthma (GINA). Relationships between the personality and the severity/duration of the disease were analysed using the ANOVA models. RESULTS 300 asthma patients aged between 17 and 79 were studied. Of these, 75% were female; the great majority had intermittent/light persistent asthma (71%); 17% had moderate persistent asthma and 12% had severe persistent asthma. The duration of the disease was less than 10 years in 34% and over 23 years in 35%. The asthma patients had higher Neuroticism scores (p < 0.001), with the other facets (except impulsiveness) equally high. All the remaining domains--Extroversion, Openness to Experience, Conscientiousness and Agreeableness--had lower scores than the control group (p < 0.001). Both Extroversion and Openness to Experience decrease with growth in the severity (p = 0.003; p = 0.009) and the duration of the disease (p = 0.006; p = 0.013). Neuroticism increases in tandem with the severity of the disease. CONCLUSION This study shows the predominance of Neurotic characteristics and lowered Extroversion, Openness to Experience, Agreeableness and Conscientiousness characteristics in asthmatics as compared to the general Portuguese population. Decreased Extroversion and Openness to Experience are observed as the severity and duration of the disease increase. Further studies are necessary to clarify the relationships between personality and the severity and duration of the disease.

Validity study: Relationship between personality and academy performance.

Abstract: We investigated the relationship between scores on the Revised NEO Personality Inventory (NEO-PIR) and police academy performance for 74 cadets. The results indicated that scores on the values and trust subscales were positively related to academy academic performance and scores on the assertiveness subscale were negatively related to academy academic performance. Sample The sample consisted of 74 cadets enrolled in three consecutive police academy classes in the St. Louis, Missouri area during the year 2001. The mean age of sample participants was 25.13 years (SD = 3.7). The majority of the officers were white (79.0%) or African American (19.6%) with a small percentage of Hispanics/Latinos (1.6%). Men comprised 80.6% of the sample. The academy was 26 weeks long.

An investigation of cognitive functioning and personality traits in obsessive-compulsive disorder, panic disorder, healthy controls and sub-clinical obsessive-compulsives

Abstract: Obsessive-compulsive disorder (OCD) is a common psychiatric illness characterised by recurrent, intrusive thoughts and repetitive, stereotyped behaviours. There is converging evidence that OCD is associated with a specific cognitive deficit related to organising and manipulating information in working memory. There is also evidence that OCD is associated with certain pre-morbid personality traits. However, further research is needed to elucidate whether these cognitive deficits and personality traits are specific to OCD or are present in other anxiety disorders and/or individuals with sub-clinical levels of obsessive-compulsive (OC) symptoms. In this thesis, 20 OCD patients were compared to 20 patients with panic disorder, 20 subjects with sub-clinical OC symptoms and 20 healthy control subjects on tests of working memory and the Five-Factor Model of personality. To measure different aspects of working memory, participants completed three delayed matching-to-sample (DMS) tasks and two continuous performance working memory tasks (n-back tasks). The DMS tasks assessed the ability to actively maintain different types of information in working memory (irregular objects; geometric objects; spatial locations). The n-back tasks assessed the ability to update and temporally order verbal and spatial stimuli in working memory. The OCD patients were less accurate than the healthy control subjects on the memory trials of the spatial DMS task, the 3- back trials of the spatial n-back task, and the 2-back and 3-back trials of the verbal n-back task. The OCD patients were also less accurate than patients with panic disorder and sub-clinical OC subjects on the verbal 3-back task. The results indicated that OCD patients were impaired on cognitive tasks requiring the maintenance of spatial stimuli and the updating and temporal ordering of verbal and spatial stimuli in working memory. The OCD patients were not impaired on tasks requiring the maintenance of object information in working memory. To measure normal personality traits, subjects completed the Revised NEO Personality Inventory (NEO PIR). Compared to healthy controls, OCD patients reported being highly emotional and introverted, less open to new experiences, and lacking confidence in their own abilities. The OCD patients were similar to the panic disorder patients on most of the domains and facets of the NEO PI-R, however, they were distinguished by their lower openness to experiencing new activities, and being less diligent and purposeful. Compared to the sub-clinical OC subjects, OCD patients reported being more prone to feelings of depression, more vulnerable to stress, less likely to experience positive emotions, more humble and sincere and less able to carry tasks through to completion. Overall, the thesis provided further evidence that OCD patients are impaired on cognitive tasks requiring the organisation and manipulation of information in working memory. However, it is still unclear whether this deficit arises due to capacity constraints being exceeded in working…
