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.

On the dimensional structure of emotional intelligence

Abstract The psychometric properties of the self-report emotional intelligence (EI) measured by Schutte et al. (1998) [Schutte, N. S., Malouff, J. M., Hall, L. E., Haggerty, D. J., Cooper, J. T., Golden, C. J., & Dornheim, L. (1998). Development and validation of a measure of emotional intelligence. Personality and Individual Differences, 25, 167–177] are scrutinized and several weaknesses are identified. It is argued that by virtue of the construction strategy adopted by Schutte et al. (1998) the test cannot be measuring a general EI factor and furthermore that it has not been successfully mapped onto Salovey and Mayers (1990) [Salovey, P., & Mayer, J. D. (1990). Emotional intelligence. Imagination, Cognition and Personality, 9, 185–211] EI model. It is also shown via confirmatory factor analysis that the test is not unifactorial. A theoretical distinction between trait and information-processing EI is proposed. Trait EI appertains to the greater personality realm whereas information-processing EI is an attempt to chart new territory in the field of human mental ability.

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. Copyright

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, psychological well-being and peer-rated social competence in adolescence

The trait emotional intelligence (trait EI or trait emotional self-efficacy) framework provides comprehensive coverage of emotion-related self-perceptions and dispositions. In this study, we investigated the relationship between trait EI and four distinct socioemotional criteria on a sample of Dutch adolescents (N = 282; 136 girls, 146 boys; mean age = 13.75 years). As hypothesized, trait EI was positively associated with adaptive coping styles and negatively associated with depressive thoughts and frequency of somatic complaints. It was also negatively associated with maladaptive coping styles, in boys only. Adolescents with high trait EI scores received more nominations from their classmates for being co-operative and girls gave significantly more nominations to classmates with high trait EI scores for having leadership qualities. The discussion focusses on the operationalization of trait emotional self-efficacy in adolescents.

Psychometric Properties of the Trait Emotional Intelligence Questionnaire (TEIQue)

This chapter presents an introduction to the theory and psychometric properties of the Trait Emotional Intelligence Questionnaire (TEIQue). We discuss the necessity of conceptualizing the increasing number of faux intelligences as personality traits, rather than as cognitive abilities, and give a detailed description of the TEIQue as the operationalization vehicle for trait emotional intelligence (trait EI or trait emotional self-efficacy). The inventory shows adequate reliability and temporal stability at the global, factor (4), and facet (15) levels. It has a clear and replicable factor structure comprising four distinct, but interrelated, dimensions: Emotionality, Self-control, Sociability, and Well-being. Self-other TEIQue correlations are substantial and similar to those observed for the Big Five. Preliminary data are presented for the new adolescent form of the TEIQue (TEIQue-AFF), which also shows satisfactory psychometric characteristics.

A psychometric analysis of the trait emotional intelligence questionnaire-short form (TEIQue-SF) using item response theory

Trait emotional intelligence refers to a constellation of emotional self-perceptions located at the lower levels of personality hierarchies. In 2 studies, we sought to examine the psychometric properties of the Trait Emotional Intelligence Questionnaire–Short Form (TEIQue–SF; Petrides, 2009) using item response theory (IRT). Study 1 (N= 1,119, 455 men) showed that most items had good discrimination and threshold parameters and high item information values. At the global level, the TEIQue–SF showed very good precision across most of the latent trait range. Study 2 (N= 866, 432 men) used similar IRT techniques in a new sample based on the latest version of the TEIQue–SF (version 1.50). Results replicated Study 1, with the instrument showing good psychometric properties at the item and global level. Overall, the 2 studies suggest the TEIQue-SF can be recommended when a rapid assessment of trait emotional intelligence is required.

Adolescents choosing self-harm as an emotion regulation strategy: The protective role of trait emotional intelligence

OBJECTIVES The present study seeks to extend the understanding of the role of dispositional factors in the aetiology of self-harm among adolescents. We hypothesized that higher trait emotional intelligence (trait EI) would be associated with a lower likelihood to harm oneself, and that this relationship would be mediated by the choice of coping strategies. DESIGN AND METHODS Trait EI, coping styles and self-harm behaviours were assessed in 490 adolescents recruited from eight British schools. RESULTS The results supported our hypothesis and showed that the relationship between trait EI and self-harm was partly mediated by the choice of coping strategies. Emotional coping was a particularly powerful mediator, suggesting that self-harm may be a way to decrease the negative emotions that are exacerbated by maladaptive emotional coping strategies, such as rumination, self-blame, and helplessness. Trait EI was correlated positively with adaptive coping styles and negatively with maladaptive coping styles, and depression. CONCLUSIONS These findings emphasize the potential value of incorporating coping coaching programmes in the treatment of self-harm patients.

A general factor of personality from multitrait-multimethod data and cross-national twins

In three studies, a General Factor of Personality (GFP) was found to occupy the apex of the hierarchical structure. In Study 1, a GFP emerged independent of method variance and accounted for 54% of the reliable variance in a multitrait-multimethod assessment of 391 Italian high school students that used self-, teacher-, and parent-ratings on the Big Five Questionnaire - Children. In Study 2, a GFP was found in the seven dimensions of Cloningers Temperament and Character Inventory as well as the Big Five of the NEO PI-R, with the GFPtci correlating r = .72 with the GFPneo. These results indicate that the GFP is practically the same in both test batteries, and its existence does not depend on being extracted using the Big Five model. The GFP accounted for 22% of the total variance in these trait measures, which were assessed in 651 pairs of 14- to 30-year-old Japanese twins. In Study 3, a GFP accounted for 32% of the total variance in nine scales derived from the NEO PI-R, the Humor Styles Questionnaire, and the Trait Emotional Intelligence Questionnaire assessed in 386 pairs of 18- to 74-year-old Canadian and U.S. twins. The GFP was found to be 50% heritable with high scores indicating openness, conscientiousness, sociability, agreeableness, emotional stability, good humor and emotional intelligence. The possible evolutionary origins of the GFP are discussed.

Explaining individual differences in scholastic behaviour and achievement

BACKGROUND This paper presents results from the first wave of a longitudinal study examining the effects of various psychosocial variables on scholastic achievement and behaviour at school. AIMS The main aim is to investigate the nature and strength of the effects of major individual difference dimensions on important outcome variables at school level, including academic performance, truancy, and antisocial behaviour. SAMPLES Data were collected from a sample of 901 pupils on verbal ability (as a proxy for cognitive ability), personality traits, and a number of behavioural indices, including academic performance at 14 and 16 years, number of authorized and unauthorized absences, and exclusions from school due to antisocial conduct. METHODS During the first stage of the study, seven schools participated in all three phases. Teachers administered a questionnaire battery in class according to a detailed protocol. Additional data were collected from school archives. RESULTS Analysis of the data through multi-group (male and female pupils) structural equation modelling indicated a very strong effect of verbal ability on academic performance. Extraversion and psychoticism were negatively related to academic performance, although their effects were weak and moderated by gender. Verbal ability, extraversion, and psychoticism predicted absenteeism, truancy, and exclusions from school due to disruptive conduct. The latter three were negatively associated with academic performance. CONCLUSIONS The findings indicate that major individual difference dimensions like verbal ability and personality traits, have a strong influence on important outcome variables at school level, including academic performance, truancy, and antisocial behaviour. Without fully acknowledging the crucial role of individual differences in shaping behaviour and achievement at school, the timely identification of pupils at risk, and the development of effective intervention schemes will be difficult.
