A behavioral genetic study of trait emotional intelligence

Numerous models of emotional intelligence (EI) have proposed the existence of hitherto undiscovered mental abilities, competencies, and skills. The theory of trait emotional intelligence suggests that the content domains of these models invariably contain permutations of personality traits. The two studies in this article examine the heritability of trait EI scores with a view to demonstrating empirically that the construct has a similar level of genetic influence as other personality traits. Study 1 was a family design of 133 high-school students and their parents. Regressions of offspring on midparent scores suggested median upper-limit heritability estimates of .18 at facet level, .25 at factor level, and .32 at the global trait EI level. Study 2 was a twin design (213 pairs of monozygotic [MZ] twins and 103 pairs of dizygotic [DZ] twins). It yielded median heritabilities of .42 for the facets, .44 for the factors, and .42 for global trait EI. Overall, our findings are in accordance with studies of the major personality dimensions and provide further empirical support for the conceptualization of EI as a personality trait.     

The location of trait emotional intelligence in personality factor space

The construct of trait emotional intelligence (trait EI or trait emotional self‐efficacy) provides a comprehensive operationalization of emotion‐related self‐perceptions and dispositions. In the first part of the present study (N = 274, 92 males), we performed two joint factor analyses to determine the location of trait EI in Eysenckian and Big Five factor space. The results showed that trait EI is a compound personality construct located at the lower levels of the two taxonomies. In the second part of the study, we performed six two‐step hierarchical regressions to investigate the incremental validity of trait EI in predicting, over and above the Giant Three and Big Five personality dimensions, six distinct criteria (life satisfaction, rumination, two adaptive and two maladaptive coping styles). Trait EI incrementally predicted four criteria over the Giant Three and five criteria over the Big Five. The discussion addresses common questions about the operationalization of emotional intelligence as a personality trait.     

Trait emotional intelligence and its links to university performance: An examination

This study aimed at investigating the relationships between academic performance (AP) and cognitive ability, personality traits, and trait emotional intelligence (trait EI or trait emotional self-efficacy) in a sample of 323 (113 female) university students in Cyprus. The study also explored differences across university majors (i.e., computer sciences, business and management, electrical engineering, tourism and marketing, law and accounting, and psychology) in trait EI profiles. Trait EI predicted AP over and above cognitive ability and established personality traits. In addition, there were differences across university majors in trait EI scores; psychology students scored higher on trait EI than computer science, electrical engineering, and business and management students. Implications for studying trait EI in the context of higher education are discussed.     

Trait emotional intelligence: behavioural validation in two studies of emotion recognition and reactivity to mood induction

This paper presents two experiments concerning trait emotional intelligence (‘trait EI’). In study 1, ten high and ten low trait EI individuals were selected from a sample of 85 persons to participate in a computerized experiment involving the recognition of morphed emotional expressions. As hypothesized, high trait EI participants were faster at identifying the expressions than their low trait EI counterparts. In study 2, trait EI scores from 102 persons were residualized on the Big Five and subsequently 15 high and 15 low trait EI individuals were selected to participate in a mood induction experiment. As hypothesized, high trait EI participants exhibited greater sensitivity to the mood induction procedure than their low trait EI counterparts. The findings are discussed in terms of the construct validity of trait EI, with particular emphasis on the issue of incremental validity vis‐à‐vis broad personality traits.

EQ-nomics: Understanding the relationship between individual differences in Trait Emotional Intelligence and entrepreneurship

Past studies highlight the importance of Trait Emotional Intelligence (EI) in the prediction of career success. Given the evidence that trait EI predicts job performance and job satisfaction, it is reasonable to expect this construct to also predict other forms of career success. In this study, we examine whether EI predicts entrepreneurship; that is, whether higher trait EI is linked to entrepreneurial behaviours and entrepreneurial success, and whether any effects of trait EI on entrepreneurship are independent of the personality trait of Core Self-Evaluations, demographic variables, and individual differences in entrepreneurial personality. Results show that trait EI predicts only some entrepreneurial outcomes beyond other variables examined, and with small effect sizes. This suggests that individual differences in entrepreneurship result only in part from inter-personal differences in trait EI. Implications for research and practice are discussed.

The dimensional structure of the emotional self‐efficacy scale (ESES)

This study aims to investigate the underlying dimensionality of the emotional self‐efficacy scale (ESES) and determine its relationship with measures of ability emotional intelligence (EI) (Mayer–Salovey–Caruso EI Test), trait EI (Trait EI Questionnaire), personality, and cognitive ability. Participants included 822 undergraduate students and 263 graduates already in the workplace. Analyses of the data suggested a multidimensional factor structure for the ESES. The measure was found to correlate with trait EI and showed expected correlations with personality. It did not correlate with ability EI or cognitive ability. These findings are discussed and are interpreted as offering support for the use of the ESES as a reliable measure of emotional self‐efficacy.     

Gender-linked personality and mental health: The role of trait emotional intelligence

The present study examined the role of the emotion-related personality dimension, or trait emotional intelligence (EI), in the relationship between gender-linked personality (GLP) traits and internalizing mental health difficulties (IMHDs). GLP traits were measured as Agency and Communion, due to conceptual advantages over other semantic representations (e.g., masculinity, femininity) in the literature. IMHDs as the outcome variable were conceptualized as a latent composite of anxiety, stress, and emotion-oriented coping. A moderate relationship between Agency and IMHDs was fully mediated by trait EI. Trait EI also divided an overall non-significant effect of Communion on IMHDs into an indirect, protective effect via trait EI and a direct, adverse effect. The results suggest that Agency and Communion subsume different sets of trait EI facets, which may account for much of the differential protective effects of these GLP traits on IMHDs. Discussion focuses on implications of the results for sex differences in mental health.     

Trait emotional intelligence: psychometric investigation with reference to established trait taxonomies

This paper sets out the theoretical foundation of emotional intelligence (EI) as a constellation of traits and self‐perceived abilities. The discriminant validity of trait EI is explored in two studies. In study 1 (N = 227), the psychometric properties of the BarOn Emotional Quotient inventory were scrutinized through confirmatory factor analysis and the measure was found to be unifactorial. When the EQ‐i was examined concurrently with the Eysenck Personality Profiler, a clear trait EI factor emerged in Eysenckian factor space. In study 2 (N = 166), a modified version of the EQ‐i was examined concurrently with the NEO PI‐R and a truncated trait EI factor was isolated within the Five‐Factor Model. Results are discussed with explicit reference to established personality models and it is concluded that trait EI can be conceptualized as a distinct composite construct at the primary level of hierarchical trait structures.

Associations of Trait Emotional Intelligence with Social Support,Work Engagement,and Creativity in Japanese Eldercare Nurses

Work‐related resources can be positive antecedents of employee work engagement (WE) and creativity. Although trait emotional intelligence (EI) and social support may be crucial resources in nursing, their relationships with WE and creativity remain unclear. Hence, with special focus on the role of trait EI, we examined this relationship by applying the job demands‐resources (JD‐R) model. The participants were 489 eldercare nurses in Japan (female: n = 401; male: n = 88; age = 39.5 ± 11.0 years). The results showed positive associations between EI and the other studied variables. Furthermore, moderated mediation analyses revealed that higher trait EI enhanced the positive association among the triad of social support, WE, and creativity. The findings provide additional evidence that, in nurses, trait EI may be a noteworthy personal resource for creativity in the relationship between social support and WE.     

Emotional intelligence, personality and the decoding of non-verbal expressions of emotion

Previous research has highlighted theoretical and empirical links between measures of both personality and trait emotional intelligence (EI), and the ability to decode facial expressions of emotion. Research has also found that the posed, static characteristics of the photographic stimuli used to explore these links affects the decoding process and differentiates them from the natural expressions they represent. This undermines the ecological validity of established trait-emotion decoding relationships.This study addresses these methodological shortcomings by testing relationships between the reliability of participant ratings of dynamic, spontaneously elicited expressions of emotion with personality and trait EI. Fifty participants completed personality and self-report EI questionnaires, and used a computer-logging program to continuously rate change in emotional intensity expressed in video clips. Each clip was rated twice to obtain an intra-rater reliability score. The results provide limited support for links between both trait EI and personality variables and how reliably we decode natural expressions of emotion. Limitations and future directions are discussed.     

The relationship between trait emotional intelligence and creativity across subject domains

This study investigated the association between two creativity indicators: Divergent Thinking (DT) and Creative Personality (CP), and key aspects of cognitive ability, personality (Big Five), and trait emotional intelligence (trait EI or trait emotional self-efficacy). The sample consisted of 175 Spanish undergraduates and recent graduates from three university subject domains: Technical & Natural Sciences, Social Sciences, and Arts. Cognitive ability was found to bear little relationship to either index of creativity. In contrast, strong relationships were demonstrated between personality traits, including trait EI, and creativity, some of which varied significantly across subject domains. Results suggest that future research will have to pay particular attention to individual differences in the affective parts of the personality realm that are comprehensively captured by the construct of trait EI.

Trait emotional intelligence as a predictor of socioemotional outcomes in early adolescence

Trait emotional intelligence (EI) refers to a constellation of emotional self-perceptions located at the lower levels of personality hierarchies. This study investigated the predictive and incremental validity of this construct in a sample of 1140 pupils aged 11-13 years. Trait EI showed strong concurrent and predictive validity in relation to three measures of socioemotional competence: self-reported psychopathology as assessed by the Strengths and Difficulties Questionnaire, a sociometric measure of peer relations, and a peer-assessed measure of social behavior. Socioemotional measures were taken twice over a period of seven months. Structural equation modeling revealed trait EI and IQ effects on socioemotional competence (SEC), the former being stronger than the latter. Hierarchical regression analyses suggested an association also of trait with level of change in SEC (controlling for both IQ and SEC at time 1). The findings corroborate an important role for trait emotional intelligence in peer relations and socioemotional competence.     

Emotional intelligence predicts adolescent mental health beyond personality and cognitive ability

Emotional intelligence (EI) has been reliably linked to better mental health (Martins, Ramalho, & Morin, 2010). However, critics have argued that EI may be conceptually redundant and unable to offer anything new to the prediction of key adaptational outcomes beyond known correlates of performance, i.e., personality and cognitive ability (Brody, 2004). Although sparse, extant evidence points to differential incremental contributions from ability and trait EI in the prediction of internalising vs. externalising symptomatology in adults (e.g., [Gardner and Qualter, 2010] and [Rossen and Kranzler, 2009]). However, there is a dearth of research addressing these associations in adolescents. The current study explored the incremental validity of ability and trait EI to predict depression and disruptive behaviour beyond the ‘Big Five’ personality dimensions and general cognitive ability in a sample of 499 adolescents (mean age 13.02 years). Regression analyses found that collectively, EI made a significant, incremental contribution to the prediction of disorder in youth. However, of the two, trait EI appears the stronger predictor. Findings are discussed with reference to EI theory and directions for future research.     

How Emotional Intelligence Might Get You the Job: The Relationship Between Trait Emotional Intelligence and Faking on Personality Tests

This study examined trait emotional intelligence (EI) in relation to the ability to fake on personality tests. Undergraduate students (N = 129) were first instructed to fill out a personality inventory honestly, and subsequently in such a way as to maximize their chances of obtaining two distinctive job positions (lawyer and file clerk). Participants were able to change their scores in line with the hypothesized job profiles. Regression analyses showed that EI statistically predicted faking ability to an equal degree in both job scenarios. Finally, EI showed incremental validity over general mental ability and the Big Five personality traits in predicting the ability to fake. Possible implications of the results for the predictive validity of personality tests are discussed.     

Trait emotional intelligence influences on academic achievement and school behaviour

Background. Trait emotional intelligence (trait EI or trait emotional self‐efficacy) refers to individuals’ emotion‐related self‐perceptions ( Petrides, Furnham, & Mavroveli, 2007 ). The children's trait EI sampling domain provides comprehensive coverage of their affective personality. Preliminary evidence shows that the construct has important implications for children's psychological and behavioural adjustment. Aims. This study investigates the associations between trait EI and school outcomes, such as performance in reading, writing, and maths, peer‐rated behaviour and social competence, and self‐reported bullying behaviours in a sample of primary school children. It also examines whether trait EI scores differentiate between children with and without special educational needs (SEN). Sample. The sample comprised 565 children (274 boys and 286 girls) between the ages of 7 and 12 (M_(age)= 9.12 years, SD= 1.27 years) attending three English state primary schools. Method. Pupils completed the Trait Emotional Intelligence Questionnaire‐Child Form (TEIQue‐CF), the Guess Who peer assessment, the Peer‐Victimization Scale, and the Bullying Behaviour Scale. Additional data on achievement and SEN were collected from the school archives. Results. As predicted by trait EI theory, associations between trait EI and academic achievement were modest and limited to Year 3 children. Higher trait EI scores were related to more nominations from peers for prosocial behaviours and fewer nominations for antisocial behaviour as well as lower scores on self‐reported bulling behaviours. Furthermore, SEN students scored lower on trait EI compared to students without SEN. Conclusions. Trait EI holds important and multifaceted implications for the socialization of primary schoolchildren.     

Emotional intelligence, teamwork effectiveness, and job performance: the moderating role of job context

We advance understanding of the role of ability-based emotional intelligence (EI) and its subdimensions in the workplace by examining the mechanisms and context-based boundary conditions of the EI-performance relationship. Using a trait activation framework, we theorize that employees with higher overall EI and emotional perception ability exhibit higher teamwork effectiveness (and subsequent job performance) when working in job contexts characterized by high managerial work demands because such contexts contain salient emotion-based cues that activate employees' emotional capabilities. A sample of 212 professionals from various organizations and industries indicated support for the salutary effect of EI, above and beyond the influence of personality, cognitive ability, emotional labor job demands, job complexity, and demographic control variables. Theoretical and practical implications of the potential value of EI for workplace outcomes under contexts involving managerial complexity are discussed.     

Do core self‐evaluations and trait emotional intelligence predict subjective well‐being in dental students?

We examined unique associations between surface personality traits of emotional intelligence, core self‐evaluations, and subjective well‐being in dental students. A cross‐sectional study of 218 undergraduates showed that trait emotional intelligence (trait EI) and core self‐evaluations (CSE) predicted subjective well‐being controlling the Big Five personality traits. Structural equation modeling showed that trait EI and the neuroticism component of CSE better predicted affective components of subjective well‐being, and cognitive CSE traits (self‐esteem, self‐efficacy, and locus of control) better predicted life satisfaction, the cognitive component of subjective well‐being. These findings demonstrate the utility of a parallel‐process approach that specifies differential prediction of cognitive and affective subjective well‐being components.     

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.
