Phobic tendency within the Five-Factor and HEXACO models of personality structure

Recent research has indicated that the various specific phobias are only modestly correlated with the personality dimensions of the Big Five or Five-Factor Model (B5/FFM). We tested the hypothesis that the specific phobias would be more strongly associated with the dimensions of an alternative framework, the HEXACO model of personality structure. Self-reports on the Phobic Stimuli Response Scales (PSRS) were obtained along with self- and peer reports on measures of the B5/FFM and HEXACO dimensions from a sample of 248 non-clinical participants. The PSRS variables assessing specific phobias showed stronger correlations with the HEXACO Emotionality factor than with any B5/FFM dimension, and a stronger multiple correlation with the HEXACO factors than with the B5/FFM dimensions. Findings were similar across self- and peer reports of the personality variables. The results suggest that phobic tendency can be understood in terms of normal personality variation as conceptualized in the HEXACO framework.     

Predicting Workplace Delinquency and Integrity with the HEXACO and Five-Factor Models of Personality Structure

Recent lexical studies of personality structure suggest that there are 6, not just 5, basic dimensions of human personality variation. The most distinguishing feature of this new 6-dimensional structure, known as the HEXACO model, is the addition of a new factor named Honesty-Humility. We demonstrate that this new dimension has important implications in personnel psychology. Specifically, the HEXACO model substantially outperformed the Five-factor model (FFM) in predicting workplace delinquency based on samples obtained in 3 different countries, namely, Australia, Canada, and the Netherlands. In addition, the HEXACO model substantially outperformed the FFM in predicting scores on an overt integrity test, due to the inclusion of the Honesty-Humility dimension.     

The prediction of Honesty–Humility-related criteria by the HEXACO and Five-Factor Models of personality

We examined two questions involving the relative validity of the HEXACO and Five-Factor Models of personality structure. First, would the HEXACO model outpredict the Five-Factor Model (FFM) with regard to several diverse criteria that are conceptually relevant to the Honesty–Humility dimension of personality? If so, would the addition of a proxy Honesty–Humility scale—as computed from relevant facets of the FFM Agreeableness domain—allow the FFM to achieve predictive validities matching those of the HEXACO model? Results from self- and observer ratings in three samples (each N > 200) indicated that the HEXACO model showed considerable predictive validity advantages over the FFM. When a measure of Honesty–Humility derived from the FFM was added to the original five domains of that model, the predictive validity reached that of the HEXACO model for some criteria, but remained substantially below for others.     

The Dark Triad,the Big Five,and the HEXACO model

The “Dark Triad” of Machiavellianism, Narcissism, and psychopathy has received much research attention since the seminal article of Paulhus and Williams (2002). The introduction of the Dark Triad came shortly after the discovery of a six-dimensional model of personality characteristics, now called the HEXACO model. One of the HEXACO factors—Honesty–Humility—is essentially equivalent (at its opposite pole) to the common element shared by the Dark Triad variables. We suggest that the emergence and popularity of the Dark Triad reflect the importance of these characteristics and their underrepresentation in five-dimensional models of personality. We note that optimal prediction and understanding of criterion variables is better achieved using the HEXACO factors than using an ad hoc combination of the Big Five and a Dark Triad composite.     

Personality Traits Beyond the Big Five: Are They Within the HEXACO Space?

Paunonen (2002) recently developed the Supernumerary Personality Inventory (SPI), a measure of 10 traits that have low loadings within the space of the Big Five personality factors. If the SPI personality traits are representative of the domain of non-Big Five personality traits, then the major source of the variance in the SPI traits would be expected to correlate strongly with the sixth factor of personality, Honesty-Humility. We tested this hypothesis using self-report measures (N = 200) of the SPI traits, of the Big Five, and of the new six-dimensional ("HEXACO") structure. Results indicated that the first unrotated factor underlying the 10 SPI traits was heavily saturated with variance from Honesty-Humility (r = .65). Nevertheless, the 10 SPI traits contained substantial amounts of unique variance not accounted for by the HEXACO or the Big Five variables, highlighting the importance of the facet-level assessment of personality traits.     

The HEXACO and five-factor models of personality in relation to RIASEC vocational interests

The current study extended the empirical research on the overlap of vocational interests and personality by (a) testing hypothesized relations between RIASEC interests and the personality dimensions of the HEXACO model, and (b) exploring the HEXACO personality model's predictive advantage over the five-factor model (FFM) in capturing RIASEC interests. Results of correlations based on a sample of 437 college students (157 men and 280 women) revealed support for eight of 21 hypothesized HEXACO–RIASEC relations for men and nine of 21 for women. Results of multiple regressions revealed that HEXACO accounted for more variance in RIASEC interests than did the FFM, and that HEXACO accounted for significant incremental variance beyond that explained by the FFM in four of six RIASEC interests for men and in five of six RIASEC interests for women.     

More than the Big Five: Egoism and the HEXACO model of personality

Egoism is a personality trait that is associated with self‐enriching and self‐centred behaviours. Research has suggested that egoism lies beyond the Big Five personality factors. Recently, the HEXACO model of personality has been proposed as an alternative to the Big Five model. In three studies, the relation between the HEXACO Personality Inventory and egoism, conceptualized using three different questionnaires (DPQ Egoism, SPI Egotism and the Egoism Scale), is investigated. In all three studies, the HEXACO Honesty–Humility factor scale was the most important predictor of egoism. Additionally, in two studies in which FFM measures were used, the HEXACO Personality Inventory explained more variance in egoism than did the FFPI (Study 2) and the NEO‐PI‐R (Study 3).

God,the good life,and HEXACO: the relations among religion,subjective well-being and personality

The relations among religiousness, subjective well-being (SWB) and the HEXACO (Honesty–Humility, Emotionality, eXtraversion, Agreeableness, Conscientiousness, Openness) model of personality were studied in a Muslim population. As expected, Extraversion and Honesty-Humility factors were the strongest correlates of SWB and religiosity, respectively. Religiosity also correlated with higher levels of SWB, and explained variance in SWB beyond personality factors, showing that religion is a unique predictor of well-being. Results have been discussed within the religious orientation paradigm, and the HEXACO model of personality structure.     

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.     

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.     

The IPIP–HEXACO scales: An alternative, public-domain measure of the personality constructs in the HEXACO model

Recently, Lee and Ashton (2004) described the HEXACO Personality Inventory (HEXACO-PI), a new instrument designed to assess the six dimensions observed in lexical studies of personality structure of various languages. Here, we describe the development of an alternative measure of the HEXACO factors and their facets, using the items of the International Personality Item Pool (IPIP). The scales of the resulting IPIP–HEXACO inventory showed satisfactory psychometric properties, as assessed by internal-consistency reliability, convergent and discriminant correlations with the original HEXACO-PI scales, and factor structure. We discuss the potential usefulness of the new IPIP–HEXACO inventory and its strengths and limitations.     

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.     

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.     

A sixth personality domain that is independent of the Big Five domains: The psychometric properties of the HEXACO Personality Inventory in a Japanese sample

We investigated the reliability of the HEXACO‐Personality Inventory (HEXACO‐PI) using the NEO Five‐Factor Inventory (NEO‐FFI) and the International Personality Item Pool (IPIP) Big Five scales in a Japanese sample of 492 respondents (mean age = 20.4 years). The psychometric properties of the HEXACO‐PI were examined and found to be satisfactory. The results of the factor analysis showed that the six hypothesized personality domains were found independently. A total of 307 participants responded to the NEO‐FFI and the IPIP Big Five scales. The results showed that the five domains of the HEXACO model corresponded to the Five‐Factor domains and were relative to the Big Five personality domains as a whole, but the sixth domain, Honesty‐Humility, showed weak to moderate correlations with some factors of the NEO‐FFI and the IPIP Big Five scales. These results suggest that the Honesty‐Humility domain is independent of the five fundamental personality factors and that the HEXACO‐PI is a useful and reliable questionnaire for investigating personality structure in cross‐cultural and other context.     

Maladaptive personality functioning within the big five and the five-factor model

The five-factor model (FFM) of general personality functioning was derived originally from lexical studies of trait terms within the English language. Many studies have been conducted on the relationship of the FFM to personality disorder symptomatology but, as yet, no lexical study of the representation of maladaptive personality functioning within a language has been conducted. The current study identified the distribution of socially undesirable trait terms within each of the poles of the Big Five and compared this distribution to findings obtained with FFM personality disorder measures. The implications of the results for a FFM of personality disorders and for the FFM assessment of maladaptive personality functioning are discussed.     

Further assessment of the HEXACO Personality Inventory: two new facet scales and an observer report form

The HEXACO Personality Inventory (HEXACO-PI) operationalizes the six factors obtained from lexical studies of personality structure in several languages. In this study, psychometric properties of the HEXACO-PI were assessed using a community adult sample and also using observer reports, thereby extending the previous investigation relying only on self-reports from a college student sample. In addition to examining the original 24 HEXACO-PI facet scales, the authors also examined two new facet scales--Altruism versus Antagonism and Negative Self-Evaluation--that assess constructs located interstitially among the factors of the HEXACO space. The HEXACO-PI again showed favorable psychometric properties in terms of reliability and factor structure and also showed high levels of self/observer agreement.     

What Is Engagement? Proactivity as the Missing Link in the HEXACO Model of Personality

We tested the hypothesis that proactivity represents the engagement vector in the HEXACO model of personality. Questionnaire data were obtained in five studies, three of which consisted (mostly) of students: Study 1 (N = 188, M_age = 20.0, 89.4% women), Study 3 (N = 315, M_age = 20.4, 80.6% women), and Study 4 (N = 309 self‐ratings, M_age = 20.0, 78.3% women; N = 307 other‐ratings, M_age = 24.5, 62.2% women). Participants in the other two studies came from an ISO‐certified representative community panel: Study 2 (N = 525, M_age = 51.2, 52.0% women) and Study 5 (N = 736, M_age = 42.2, 48.0% women). Proactive Personality and Proactivity were positively related to Extraversion, Conscientiousness, and Openness to Experience, but only weakly related or unrelated to Honesty‐Humility, Emotionality, and Agreeableness, supporting the alignment of Proactive Personality/Proactivity with the hypothesized HEXACO engagement vector. Additionally, Proactivity explained incremental variance in self‐rated job performance on top of the HEXACO facets that were most closely associated with Proactive Personality/Proactivity, that is, Social Boldness (an Extraversion facet), Diligence (a Conscientiousness facet), and Creativity (an Openness to Experience facet), but not in entrepreneurship and intrapreneurship. Proactivity is the missing engagement link in the HEXACO model of personality. The results are discussed in light of higher‐order factors (e.g., general factor of personality and Alpha and Beta) of personality and bandwidth‐fidelity controversies.
