Assessing the temporal stability of a measure of trait emotional intelligence: Systematic review and empirical analysis

Determining the temporal stability of a construct is crucial to establishing its validity and utility in real-world scenarios. To-date, few studies have investigated the test-retest reliability of trait emotional intelligence (trait EI), particularly over extended periods of time. The present study presents relevant data from the Trait Emotional Intelligence Questionnaire (TEIQue) over variable intervals, ranging from 30 days (one month) to 1444 days (≈ four years). Results provide support for trait EI theory, demonstrating strong temporal stability at all levels of the construct (global, factor, and facet). Future research may focus on extending the test-retest intervals at both ends (i.e., below one month and over four years) as well as on comparisons between different trait EI measures

Maladaptive (dark-side) and adaptive (bright-side) personality traits and defense styles

This study explores the relationship between bright- and dark-side personality traits and four major styles of defense mechanisms (DMs) as this relationship remains unexplored and important in understanding the DMs. In all, 435 adult working participants (241 men; 194 women; Mean age 46.06 yrs) mainly in middle management jobs, completed a 78-item, six-trait measure of bright-side personality (HPTI: High Potential Type Indicator), a 25-item five-trait measure of the dark-side personality (PID-5;BF: DSM-5—Brief Form) and 88-item, four-styles measure of defense mechanisms (Defense Style Questionnaire). The aim was to examine demographic (sex, age, education), ideological and personality trait correlates of the DMs. It was hypothesized that the dark-side traits, particularly Detachment would be most strongly related to the DMs. Thereafter, a hierarchical linear regression was performed with each DM factor as criterion and predictors being demography, ideology, self-esteem as well as bright- and dark-side personality traits. Detachment was associated with all DMs, particularly Maladaptive (r = 0.68) and Image Distorting Style (r = 0.38) while Conscientiousness was associated with none. One implication concerns the assessment of DMs by standard tests. Limitations are acknowledged and include method invariance and sample homogeneity

Intelligence, Personality and Tolerance of Ambiguity

In this study, 3836 adults completed a personality test (the HPTI) and a multidimensional intelligence test (GIA). Two prominent theories that link personality traits to intelligence (compensation and investment) were tested. There were more sex differences in the personality traits than in the IQ scores. Correlational and regression analyses results provided little evidence for either theory but pointed to the role of tolerance of ambiguity as a consistently significant, positive correlate of IQ at both the facet and domain levels. The role of this neglected trait is discussed. Limitations of various aspects of this study and its implications are considered

Correlates of Stock Market Investment

In this study we were concerned with the correlates of stock market participation (SMP). In all, 1202 working adults indicated whether or not they invested in the stock market, and which was split almost equally between those that did, and did not. We were interested in the extent to which their demography (age, sex, education), self-assessed wealth, as well as personality traits predicted their participation. We used a six-factor robust measure of work personality (HPTI). Correlational analysis indicated that the strongest correlation of SMP were wealth, sex, age and trait Risk Tolerance. We then did a binary logistic regression which indicated that being male increased the odds of having invested in the stock market by 91%, and an increase of one year in age increased the odds by 3%. Ambiguity Acceptance and trait Competitiveness were among the HPTI personality variables that were significant predictors of stock market investment. Implications and limitations are acknowledged
