The mini-IPIP scales: tiny-yet-effective measures of the Big Five factors of personality

The Mini-IPIP, a 20-item short form of the 50-item International Personality Item Pool-Five-Factor Model measure (Goldberg, 1999), was developed and validated across five studies. The Mini-IPIP scales, with four items per Big Five trait, had consistent and acceptable internal consistencies across five studies (= at or well above .60), similar coverage of facets as other broad Big Five measures (Study 2), and test-retest correlations that were quite similar to the parent measure across intervals of a few weeks (Study 4) and several months (Study 5). Moreover, the Mini-IPIP scales showed a comparable pattern of convergent, discriminant, and criterion-related validity (Studies 2-5) with other Big Five measures. Collectively, these results indicate that the Mini-IPIP is a psychometrically acceptable and practically useful short measure of the Big Five factors of personality.     

Relation of the Big Five to Biodata and aspects of the self

Two studies examined McCrae and Costa’s system model of personality. Their model suggests the Big Five should have relatively strong associations with life history (measured in Study 1 by Biodata) and with Self-Concept (measured in Study 2 by various Self questionnaires). Study 1—210 participants (143 females) completed Bipolar Big Five Markers and a Biodata inventory. Factor Analyses confirmed the Big Five and revealed seven viable Biodata factors. Multiple regression revealed that most Biodata factors were predicted well by 2 or more Big Five traits. Study 2—199 participants (125 females) completed Bipolar Big Five Markers and an omnibus Self inventory consisting of six previously developed scales. Factor Analyses confirmed the Big Five and revealed eight viable Self factors. Multiple regression revealed that the Self factors were also predicted fairly well by two or more Big Five traits.Both studies found relatively strong associations between the Big Five and the Biodata and Self factors, which lends support to McCrae and Costa’s system model of personality. A consistent pattern of both a primary and secondary trait as joint predictors of Biodata and Self factors suggests that these areas are systematically influenced by multiple traits rather than only single traits.     

On the temporal stability of personality: evidence for differential stability and the role of life experiences

The authors investigated the stability of personality and trait affect in young adults. In Studies 1 and 2, young adults were retested on a Big Five personality measure and a trait affect inventory over a 2.5-year and a 2-month period, respectively. Results from Study 1 point to positive mean-level changes; participants scored higher on Extraversion, Openness, Agreeableness, and Conscientiousness at Time 2. Affectively, participants experienced less negative affect and more positive affect at Time 2. Results from both retests provide clear evidence of differential stability. Affective traits were consistently less stable than the Big Five. Other analyses suggest that life events influence the stability of affective traits more than the Big Five.     

Self-other agreement in personality and affectivity: the role of acquaintanceship, trait visibility, and assumed similarity

Self- and other-ratings on the Big Five and a comprehensive inventory of trait affect were obtained from 74 married couples, 136 dating couples, and 279 friendship dyads. With the exception of Surprise, all scales showed significant self-other agreement in all 3 samples, thereby establishing their convergent validity. Consistent with the trait visibility effect, however, the Big Five consistently yielded higher agreement correlations than did the affectivity scales. Conversely, the affective traits consistently showed stronger evidence of assumed similarity (i.e., the tendency for judges to rate others as similar to themselves) than did the Big Five. Cross-sample comparisons indicated that agreement was significantly higher in the married sample than in the other 2 groups; however, analyses of 3 potential moderators in the dating and friendship samples failed to identify the source of this acquaintanceship effect.     

Anger and hostility from the perspective of the Big Five personality model

Sanz, J., García‐Vera, M. P. & Magán, I. (2010). Anger and hostility from the perspective of the Big Five personality model. Scandinavian Journal of Psychology, 51, 262–270. This study was aimed at examining the relationships of the personality dimensions of the five‐factor model or Big Five with trait anger and with two specific traits of hostility (mistrust and confrontational attitude), and identifying the similarities and differences between trait anger and hostility in the framework of the Big Five. In a sample of 353 male and female adults, the Big Five explained a significant percentage of individual differences in trait anger and hostility after controlling the effects due to the relationship between both constructs and content overlapping across scales. In addition, trait anger was primarily associated with neuroticism, whereas mistrust and confrontational attitude were principally related to low agreeableness. These findings are discussed in the context of the anger‐hostility‐aggression syndrome and the capability of the Big Five for organizing and clarifying related personality constructs.     

Testing and validating the trait emotional intelligence questionnaire (TEIQue) in a German-speaking sample

The trait emotional intelligence questionnaire (TEIQue) was tested and validated using a sample of 352 German-speaking participants. A detailed psychometric analysis provided evidence in support of the reliability of the TEIQue (at the facet, factor and global levels) and the robustness of its proposed four-factor structure. Using a subsample of 150 participants, the associations between the TEIQue and a series of relevant constructs (Big Five, life satisfaction, somatic complaints) were examined, which also included data on other trait EI measures. Overall, the TEIQue showed theoretically expected relationships to all other constructs and incremental validity in the prediction of life satisfaction and somatic complaints over and above the Big Five as well as all other trait EI measures combined.     

Bridging the idiographic-nomothetic divide: a follow-up study

In a replication and extension of Grice (2004), participants in the current study rated themselves and other known individuals on scales constructed from their own personal constructs and on marker items for the Big Five model personality traits. Confirmatory components analyses revealed excellent fit for the Big Five Model when applied to aggregate trait ratings but highly variable fit when applied to participants' individual ratings. Comparisons of the personal construct and trait ratings indicated an approximate average overlap of only 51%, and additional analyses revealed several factors that contributed to the uniqueness of the personal constructs. These findings were discussed in the context of the idiographic-nomothetic distinction drawn in personality psychology.     

Dreaming and personality: Wake-dream continuity,thought suppression,and the Big Five Inventory

Studies have found relationships between dream content and personality traits, but there are still many traits that have been underexplored or have had questionable conclusions drawn about them. Experimental work has found a ‘rebound’ effect in dreams when thoughts are suppressed prior to sleep, but the effect of trait thought suppression on dream content has not yet been researched. In the present study participants (N = 106) reported their Most Recent Dream, answered questions about the content of the dream, and completed questionnaires measuring trait thought suppression and the ‘Big Five’ personality traits. Of these, 83 were suitably recent for analyses. A significant positive correlation was found between trait thought suppression and participants’ ratings of dreaming of waking-life emotions, and high suppressors reported dreaming more of their waking-life emotions than low suppressors did. The results may lend support to the compensation theory of dreams, and/or the ironic process theory of mental control.     

Affect,Behaviour, Cognition and Desire in the Big Five: An Analysis of Item Content and Structure

Personality psychology is concerned with affect (A), behaviour (B), cognition (C) and desire (D), and personality traits have been defined conceptually as abstractions used to either explain or summarise coherent ABC (and sometimes D) patterns over time and space. However, this conceptual definition of traits has not been reflected in their operationalisation, possibly resulting in theoretical and practical limitations to current trait inventories. Thus, the goal of this project was to determine the affective, behavioural, cognitive and desire (ABCD) components of Big‐Five personality traits. The first study assessed the ABCD content of items measuring Big‐Five traits in order to determine the ABCD composition of traits and identify items measuring relatively high amounts of only one ABCD content. The second study examined the correlational structure of scales constructed from items assessing ABCD content via a large, web‐based study. An assessment of Big‐Five traits that delineates ABCD components of each trait is presented, and the discussion focuses on how this assessment builds upon current approaches of assessing personality.

Body image and personality: Associations between the Big Five Personality Factors,actual‐ideal weight discrepancy,and body appreciation

Studies have suggested associations between personality dimensions and body image constructs, but these have not been conclusively established. In two studies, we examined direct associations between the Big Five dimensions and two body image constructs, actual‐ideal weight discrepancy and body appreciation. In Study 1, 950 women completed measures of both body image constructs and a brief measure of the Big Five dimensions. In Study 2, 339 women completed measures of the body image constructs and a more reliable measure of the Big Five. Both studies showed that Neuroticism was significantly associated with actual‐ideal weight discrepancy (positively) and body appreciation (negatively) once the effects of body mass index and social status had been accounted for. These results are consistent with the suggestion that Neuroticism is a trait of public health significance requiring attention by body image scholars.     

The happy personality: Mediational role of trait emotional intelligence

This study examined the relationship between the Big Five personality traits (Gosling et al., 2003), trait emotional intelligence (EI) (Petrides & Furnham, 2001) and happiness (Argyle et al., 1989) in a sample of 112 (61 female) student and non-student participants. Strong dispositional determinants of happiness were identified. In line with previous findings, four of the Big Five, namely stability, extraversion, conscientiousness, and agreeableness, were positively correlated with both happiness and trait EI, which explained 18% of unique variance (over and above age and the Big Five) in happiness. Furthermore, a significant amount of shared variance between happiness and the Big Five was explained by trait EI, which partly mediated the paths from stability and conscientiousness to happiness, and fully mediated the link between agreeableness and happiness. Limitations and implications are discussed.     

Trait aggression is primarily a facet of antagonism: Evidence from dominance,latent correlational,and item-level analyses

Trait aggression has been studied for decades and yet remains adrift from broader frameworks of personality such as the Five Factor Model. Across two datasets from undergraduate participants (Study 1: N = 359; Study 2; N = 620), we observed strong manifest and latent correlations between trait aggression and lower agreeableness (i.e., greater antagonism). Trait aggression was also linked to greater neuroticism and lower conscientiousness, but their effect sizes fell beneath our preregistered threshold. Subsequent item-level analyses were unable to articulate trait aggression and agreeableness items into separate factors using the IPIP-NEO, but not the Big Five Inventory. Our findings suggest that trait aggression is accurately characterized as primarily a facet of antagonism, while also reflecting other personality dimensions.     

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.     

Has Average Joe Got Inner Conflicts? Positioning the Self and the Meaning of Mid-Range Scores on the Big Five Traits

In this article we explore dilemmas with interpreting mid-range scores on Big Five personality traits. Using dialogical self theory, we hypothesized that mid-trait individuals would report more conflict between I-positions congruent with the trait domain concerned, for example, conflict between I-as-bold and I-as-reserved in the domain of Extraversion. A community sample of 147 participants completed a Big Five trait measure, the NEO Personality Inventory (NEO PI-R), and the I-Position Inventory (IPI). The IPI contains 88 I-position statements generated from previous research and clinical assessments. Fifty-two of the statements form 26 opposing pairs (e.g., I-as-optimist vs. I-as-pessimist). To measure the most salient I-position conflicts, respondents were asked to rank these pairs (only the top five pairs were ranked). In support of the conflict hypothesis, for three of the Big Five traits, individuals who scored mid-range reported more conflict between I-positions congruent with the trait than did respondents in the upper and lower quartiles of the distribution (significant for Extraversion, Openness to Experience, and Agreeableness). We argue the findings highlight problems of interpretation for mid-range trait scores that arise from the limitations of aggregation methods, but also from a compromised theoretical foundation. Trait theory masks dynamic processes as well as social contexts.     

Integration of the big five and circumplex approaches to trait structure.

To integrate the 5-dimensional simple-structure and circumplex models of personality, the Abridged Big Five Dimensional Circumplex (AB5C) taxonomy of personality traits was developed, consisting of the 10 circumplexes that can be formed by pitting each of the Big Five factors against one another. The model maps facets of the Big Five dimensions as blends of 2 factors. An application to data consisting of 636 self-ratings and peer ratings on 540 personality trait adjectives yielded 34 well-defined facets out of a possible 45. The AB5C solution is compared with simple-structure and lower dimensional circumplex solutions, and its integrative and corrective potential are discussed, as well as its limitations.     

The content and structure of laypeople's concept of pleasure

Five studies were conducted to map the content and structure of laypeople's conceptions of pleasure. Instances of the pleasure concept collected in Study 1 consisted predominantly of objects, events or persons described as sources of pleasure. Content analysis suggested that the pleasure category, like emotional response categories, might be formed at an implicit level where various pleasure antecedents are grouped based on common phenomenological qualities of the affective experience. Studies 2 and 3a showed that the pleasure category possesses a graded structure and fuzzy boundaries. Results further revealed that, either when explicitly presented with labels (Study 3b) or left to their own implicit categories during a sorting task (Study 4), laypeople represented pleasure as a hierarchical concept in which differentiated pleasure types (i.e., intellectual, emotional, social and physical) were subsumed under a higher level unitary form of pleasure. In this structure, unitary and differentiated pleasures shared a set of common affective qualities but were also distinguishable by unique and distinctive affective characteristics (Study 5). Ties to prior theories of pleasure and implications for decision making and behavioural research are discussed.
