A General Factor of Personality (GFP) from two meta-analyses of the Big Five: and

In two studies, we used structural equation models to test the hypothesis that a General Factor of Personality (GFP) occupies the apex of the hierarchy of personality. In Study 1, we found a GFP that explained 45% of the reliable variance in a model that went from the Big Five to the Big Two to the Big One in the 14 studies of inter-scale correlations (N = 4496) assembled by Digman (1997). A higher order factor of Alpha/Stability was defined by Conscientiousness, Emotional Stability, and Agreeableness, with loadings of from 0.61 to 0.70, while Beta/Plasticity was defined by Openness and Extraversion with loadings of 0.55 and 0.77. In turn, the GFP was defined by Alpha and Beta with loadings of 0.67. In Study 2, a GFP explained 44% of the reliable variance in a similar model using data from a published meta-analysis of the Big Five (N = 4000) by Mount, Barrick, Scullen, and Rounds (2005). Strong general factors such as these, based on large data sets with good model fits that cross validate perfectly, are unlikely to be due to artifacts and response sets.     

Evidence for the role of the General Factor of Personality (GFP) in enculturation: The GFP and self-construal in Japanese and American samples

Data from Midlife in the United States (MIDUS) studies, one with American participants and one with Japanese participants, were used to test the hypothesis that the General Factor of Personality (GFP) is positively associated with enculturation. To this end, the relationships between the GFP and independent self-construal and interdependent self-construal were examined. Consistent with the hypothesis, the results showed that an independent self-construal was more closely associated with the GFP in the American sample.     

Don’t be afraid of the General Factor of Personality (GFP): Its relationship with behavioral inhibition and anxiety symptoms in children

Two studies examined the relationship between the General Factor of Personality (GFP) and behavioral inhibition and anxiety symptoms in primary school children. The GFP is assumed to reflect effectiveness in interaction with others. In Study 1, using self-reports and parent ratings of 226 non-clinical children, we found GFP scores to be negatively related to behavioral inhibition and anxiety symptoms. In Study 2 we compared non-clinical children (N = 81) with children with anxiety disorders (N = 45). In both groups we obtained child and parent ratings. The clinically referred children scored significantly lower on the GFP than the non-clinical children. Moreover, as in Study 1, higher GFP scores were associated with lower levels of behavioral inhibition and anxiety symptoms. The two studies support the view that the GFP is a relevant construct in anxiety proneness and anxiety problems.     

The General Factor of Personality and Character: A Reanalysis

Using data from the Texas Twin Project, it was recently reported that 7 measures of character covaried to the extent that they formed a general factor of character (Tucker-Drob, Briley, Engelhardt, Mann, &; Harden, 2016 Tucker-Drob, E. M., Briley, D. A., Engelhardt, L. E., Mann, F. D., &; Harden, K. P. (2016). Genetically-mediated associations between measures of childhood character and academic achievement. Journal of Personality and Social Psychology, 111, 790–815. doi:10.1037/pspp0000098.[Crossref] , [Google Scholar]). In turn the relationship between the general factor of character and the Big Five personality traits were examined. It was found that personality was associated with the general factor of character primarily through the traits of conscientiousness and openness. For several reasons we propose that a more accurate interpretation of the data is that a Big Five personality traits form a general factor of personality, and that the relationship between the general character factor and personality is primarily through the general factor of personality. The results lend some support to this contention and are discussed in relation to the growing interest in covariation among multiple personality traits.     

The General Factor of Personality: A critical test

The present study provides evidence supporting the presence of a General Factor of Personality (GFP), which has been proposed to represent the apex of the hierarchy of personality traits. Furthermore, the construct validity of this general factor is assessed to address recent criticisms suggesting that the GFP may merely be a statistical artefact rather than a genuine higher-order personality dimension. In this study, two samples of monozygotic (MZ) and same-sex dizygotic (DZ) twins completed the NEO Personality Inventory-Revised (NEO-PI-IR), assessing individual differences in the Big Five traits of personality, and the Dimensional Assessment of Personality Problems-Differential Questionnaire (DAPP-DQ) measuring variance in abnormal personality traits. First unrotated factors were extracted from each of the two measures separately within each sample. Correlations between these factors were significant and high in both samples (.78 and .77), indicating that the factors represent similar constructs. The manner in which these findings help to validate the GFP is discussed.     

The Elusive General Factor of Personality: The Acquaintance Effect

A general factor (g_p) at the apex of personality has been suggested to account for the correlations between the Big Five. Although the g_p has received ample support from monomethod studies, results from studies incorporating different methods have remained rather ambiguous; some have identified a g_p across different informants, whereas others have not. It was hypothesized that these divergent findings are a result of varying lengths of acquaintance between raters. To this end, the current study presents a multitrait multi‐informant meta‐analysis (total N = 11 941) that found weak support for a g_p as a substantive trait of personality. Evidence for a g_p was susceptible to the length of acquaintance between informants. Although a g_p could be identified for short‐term acquaintances, it remained elusive at long‐term acquaintance. Thus, the g_p in other ratings more likely reflects normative ratings of an average individual rather than ratings of the specific target person.

The General Factor of Personality (GFP) Relates to Other Ratings of Character and Integrity: Two validity studies in personnel selection and training of the Dutch armed forces

In two studies, we tested whether scores on the general factor of personality (GFP) are associated with other ratings of character and integrity. In Study 1, a total of 3,670 applicants for a military job filled out personality surveys and went through a selection interview. GFPs extracted from two different personality surveys showed meaningful relationships with the job suitability judgments based on the interviews. In Study 2, supervisors rated the integrity of participants (N = 167) who followed a 4‐month military training at the Royal Dutch Military Police. GFPs extracted from three different surveys were correlated with integrity. The findings imply that the GFP is associated with behavioral outcomes, and that the GFP is potentially relevant for personnel selection and appraisal.     

The General Factor of Personality: A reply to Muncer

In previous studies we have shown that a General Factor of Personality (GFP) occupies the apex of the hierarchy of personality as well as the apex of the personality disorders in the same way that g, the general factor of mental ability, occupies the apex in the organization of cognitive abilities (Rushton & Irwing, 2011). In a critique, Muncer (2011) re-analyzed one of our data sets and concluded there was no evidence for a GFP. He also argued against the evolutionary theory we had proposed for the origin of the GFP. In this rejoinder I rebut Muncer’s conclusion and describe how directional selection can explain the GFP.     

The General Factor of Personality and peer-rated social status: A rejoinder to de Vries (2011)

In a previous study we showed that self-reported Big Five scores and the General Factor of Personality (GFP) were related to peer-ratings of likeability and popularity (van der Linden, Scholte, et al., 2010). de Vries (2011a) re-analyzed our data and concluded that (i) there was no evidence of a GFP, and (ii) the GFP we used was latent factor of Extraversion. In this rejoinder I present arguments that compromise the re-analysis and conclusions as described by de Vries (2011a) and emphasize the relevance of the GFP.     

No evidence for a General Factor of Personality in the HEXACO Personality Inventory

There have been an increasing number of articles that have speculated on the existence of a General Factor of Personality (GFP) similar to ‘g’ in intelligence research. In this study, I provide evidence that this general factor may be an artifact of the personality instrument used. Specifically, in two samples I show that depending on the type of analysis used there is either no evidence for a GFP in the HEXACO Personality Inventory or the GFP is found to be uncorrelated to GFPs based on Big Five or FFM instruments.     

Revaluating the evidence for the General Factor of Personality in the Multidimensional Personality Questionnaire: Concerns about Rushton and Irwing (2009)

We evaluated whether the Big Five-based hierarchical model for the Multidimensional Personality Questionnaire (MPQ) reported by Rushton and Irwing (2009) would replicate in a second sample of 733 participants. We were unable to confirm their hierarchical model and detected problems with the reporting of the original results. Exploratory factor analytic investigations generally supported the canonical three factor solution for the MPQ described in the existing literature. This was the case for both the present dataset and for the correlation matrix analyzed by Rushton and Irwing.     

The General Factor of Personality in selection and assessment samples

In two large samples (N₁ = 44,971, N₂ = 7793) we tested the General Factor of Personality (GFP) in the Big Five, measured during selection and assessment. A GFP could clearly be identified in the data, explaining approximately 50% of the Big Five variance. We found indications for socially desirable response tendencies in a subgroup that was tested for selection purposes. Yet, this tendency did not affect the personality factor structure or the GFP characteristics. Moreover, in the selection sample, the GFP was moderately related to the Overall Assessment Rating. The findings confirm the GFP in an applied setting and support the idea that the GFP does not merely reflect methodological artifacts but is substantive.     

The General Factor of Psychosocial Development and its relation to the General Factor of Personality and Life History strategy

It was hypothesized that the eight Eriksonian psychosocial stages form a single latent variable or General Factor of Psychosocial Development (GFPD) and that this latent factor is associated with the General Factor of Personality (GFP) and Life History (LH) strategy to the extent that the variables form a higher order Super-K factor. Correlational analyses and confirmatory factor analyses each supported the hypothesized GFPD. Additionally, correlational and confirmatory factor analyses supported the hypothesis that the three variables form a single Super-K factor. The results of Study 3 suggest that the relationship between the psychosocial stages and between the GFPD, GFP, and LH strategy remained after controlling for social desirable response biases.     

Personality Disorders Are Not as We Thought: Hierarchical Factor Structure at the Criterion Level

The use of personality disorder (PD) categories persists, despite the evidence against them. An often overlooked reason for this is the fact that the true structure underlying the Diagnostic and Statistical Manual of Mental Disorders (DSM) taxonomy is still unknown: We cannot be certain which disorders are valid, and which ones are arbitrary mixtures of heterogeneous traits. To address this gap, we factor analyzed the Personality Diagnostic Questionnaire (PDQ–4+; Hyler, 1994 Hyler, S. E. (1994). PDQ–4+ Personality Diagnostic Questionnaire–4+. New York, NY: New York State Psychiatric Institute. [Google Scholar]) at the criterion level in a mixed clinical and nonclinical sample of 2,519 individuals. The resulting structure was more similar to current dimensional taxonomies than to the DSM classification at all hierarchical levels. Whereas paranoid and antisocial PDs—and to a lesser extent avoidant, dependent, depressive, and schizoid PDs—were fairly homogeneous, all other disorders turned out to be combinations of 2 or 3 unrelated dimensions. Our results strongly support the structure of empirically based dimensional taxonomies and relocate DSM criteria within this emerging framework, thus contributing to preserving much of the knowledge accumulated to date.     

Convergence of Vocational Interests and Personality: Examples in an Adolescent Gifted Sample

This investigation explored the convergence between vocational interests as measured by the Strong Interest Inventory (Hansen & Campbell, 1985) and two competing personality models: the Big Five as measured by the NEO Personality Inventory-Revised (NEO-PI-R) (Costa & McCrae, 1992) and the Big Three as measured by the Multidimensional Personality Questionnaire (MPQ) (Tellegen, 1982; Tellegen & Waller, in press). The participants were 323 gifted adolescents. The authors predicted that specific NEO-PI-R facet scales and specific MPQ primary scales would add meaningful variance to the prediction of hypothesized Basic Interest Scales (BISs) on the Strong after the variation due to the respective Big Five or Big Three factors was removed. The predictions were largely supported. Moreover, this study provided additional evidence regarding convergence of Holland's Big Six and the Big Five model of personality. This study could serve to prompt a new generation of studies relating vocational interests and personality.     

Misconstruing methods and meaning in the General Factor of Personality

Research has suggested that a General Factor of Personality (GFP) might represent a real and meaningful higher‐order factor in the personality hierarchy. However, there are psychometric shortcomings in many of the studies used to support this argument, as well as convincing empirical evidence for alternative explanations of the GFP as methodological rather than meaningful. The current article re‐examines the research supporting a substantive GFP by considering and evaluating the evidence presented in a recent volume (Just, 2011). It is concluded that covariation among first‐order personality factors is more likely a statistical or methodological artefact than a theoretically meaningful higher‐order construct.     

Personality Types and Vocational Choice: A Test of Holland's Theory

In order to test the adequacy of Holland's theory of vocational choice with reference to a broad segment of entering college students, a sample of the freshman class entering the Pennsylvania State University evaluated themselves in terms of the six personality styles of Holland's theory. Relationships between the personality styles and vocational choices were studied for groups of Decided, Tentative, and Undecided students. While several inversions in the data are evident, the data possess sufficient consistency to indicate that the personality identifications these students made in Holland's frame of reference were related to their initial vocational choices.     

Predicting Sales Performance Criteria With Personality Measures: The Use of the General Factor of Personality,the Big Five and Narrow Traits

The present study investigated the predictive validities of different hierarchical levels of personality for sales performance. The General Factor of Personality was expected to be most effective at predicting general sales performance, whereas the Big Five factors and its underlying narrow traits were expected to be most effective at predicting the specific sales performance criteria to which they are conceptually aligned. Six different sales performance measures were used in an international study involving 405 sales employees. The results suggest that General Factor of Personality is a valid predictor of general job performance but that some of the aligned narrow personality traits predict specific sales performance above and beyond the Big Five factors. The narrow trait Social Boldness has a negative relation with rated sales performance and sales results.
