Many interconnected factors have been implicated in the prediction of whether a given individual occupies a managerial role. These include an assortment of demographic variables such as age and gender as well as trait emotional intelligence (trait EI) and cognitive ability. In order to disentangle their respective effects on formal leadership posit...

In the era of machine learning, many psychological studies use machine learning methods. Specifically, neural networks, a set of machine learning methods that exhibit exceptional performance in various tasks, have been used on psychometric datasets for supervised model fitting. From the computer scientist’s perspective, psychometric independent var...

Introduction Interventional radiology (IR) is a rapidly developing speciality where innovation—especially in teaching practices—is vital. With workforce and capacity shortages, synthesis of classical educational theories and novel strategies utilising virtual reality (VR) and artificial intelligence (AI) provide opportunities to make teaching as ef...

Psychologists are emphasizing the importance of predictive conclusions. Machine learning methods, such as supervised neural networks, have been used in psychological studies as they naturally fit prediction tasks. However, we are concerned about whether neural networks fitted with random datasets (i.e., datasets where there is no relationship betwe...

A range of stand-alone psychological trait measures have been shown to considerably overlap with the Big Five (Bainbridge et al., 2022). Recognizing such construct overlap is essential for consolidation. We propose, however, that the notion that many psychological scales are overlapping with the Big Five is valid, but incomplete. Accordingly, we su...

This study aims to cross-culturally adapt and examine the psychometric properties of the Kuwaiti-Arabic Trait Emotional Intelligence-Short Form (TEIQue-SF) through structural equation modeling (SEM). The adapted measure was administered to 1,458 university students in Kuwait together with the Kuwaiti NEO-FFI. Reliability estimates for all TEIQue-SF...

Trait emotional intelligence (trait EI) has a protective role in adolescence, linked to better well-being and social interactions. However, research on these topics with adolescent samples is limited and has not yet been systematized in the field. The present work aims to scrutinize the extant trait EI literature and adolescent psychological well-b...

Monte Carlo simulation is a common method of providing empirical evidence to verify statistics used in psychological studies. A representative set of conditions should be included in simulation studies. However, several recently published Monte Carlo simulation studies have not included the conditions of the null distribution of the statistic in th...

The main aim of this study is to introduce an implicit personality assessment method (e.g., implicit association test) to Kuwait. We adapted an existing personality-related implicit association test (IAT; Big Five IAT), while also constructed the first trait EI IAT based on Petrides’ four-factor model. We investigated the psychometric properties of...

Evidence shows that Emotional Intelligence (EI) can be improved through training. Yet, more theoretically sound, culturally sensitive, and rigorous EI programs are needed. Funded by Grand Challenges Canada-NIHS, we developed “Yes to Emotions in Youth (YEY)”, an evidence-based, youth-led EI training for vulnerable Lebanese youth. YEY followed a quas...

Parental burnout (PB) is a pervasive phenomenon. Parenting is embedded in cultural values, and previous research has shown the role of individualism in PB. In this paper, we reanalyze previously collected data to identify profiles based on the four dimensions of PB, and explore whether these profiles vary across countries’ levels of collectivistic-...

This article presents findings on the personality traits of individuals who identified as either Vaxxers (V) or Anti-Vaxxers (AV) during the COVID-19 pandemic. The study administered measures of Dark Triad traits (Machiavellianism, Narcissism, and Psychopathy), trait emotional intelligence, and personality to a sample of 479 participants (283 Vs an...

Purpose The prevalence of parental burnout, a condition that has severe consequences for both parents and children, varies dramatically across countries and is highest in Western countries characterized by high individualism. Method In this study, we examined the mediators of the relationship between individualism measured at the country level and...

The WHO estimates that nearly one in three women are subjected to abuse by their partner. This paper aimed to evaluate the extent to which low emotional intelligence might contribute to a woman's participation in an abusive relationship. Three hundred and eight one adult women completed the Trait Emotional Intelligence Questionnaire (TEIQue), which...

Trait emotional intelligence concerns people’s perceptions of their emotional world. Our aims for this study are to examine (a) the trait emotional intelligence (EI) profiles across different professions in Kuwait; (b) the incremental validity of trait EI in predicting job performance; and (c) the relationship between trait EI, job attitudes, and j...

What is it to be “an ideal parent”? Does the answer differ across countries and social classes? To answer these questions in a way that minimizes bias and ethnocentrism, we used open-ended questions to explore ideal-parent beliefs among 8,357 mothers and 3,517 fathers from 37 countries. Leximancer Semantic Network Analysis was utilized to first det...

Purpose The prevalence of parental burnout, a condition that has severe consequences for both parents and children, varies dramatically across countries and is highest in Western countries characterized by high individualism. Method In this study, we examined the mediators of the relationship between individualism measured at the country level and...

There is a dearth of trait emotional intelligence (trait EI) research within an aviation context. Using the Trait Emotional Intelligence Questionnaire (TEIQue), the present study investigated potential trait EI differences between pilots and general population controls in the United States. The forty-four pilots who volunteered to participate were...

Studies have consistently reported the negative effect of COVID-19 on psychopathology, including increased symptoms of depression and anxiety. Taking a positive psychology approach, the present study investigated the role of trait emotional intelligence (EI), state mindfulness, and self-care on both psychopathological symptoms (depression and anxie...

Recent research has shown that cultural, linguistic, and sociodemographic peculiarities influence the measurement of trait emotional intelligence (trait EI). Assessing trait EI in different populations fosters cross-cultural research and expands the construct’s nomological network. In mental health, the trait EI of clinical populations has been sca...

The study of the relationship between reasoning and emotional processes is not new in Psychology. There are currently two main approaches to understanding the aspects related to these processes called emotional intelligence: the ability model and the trait model. This study focuses on the latter, analyzing the factor structure, reliability, and val...

Trait emotional intelligence (trait EI or trait emotional self-efficacy) concerns people’s perceptions of their emotional functioning. Two studies investigated this construct in surgeons and comparison occupations. We hypothesized that trait EI profiles would differ both within surgical specialties as well as between them and other professions. Stu...

In Western countries, recent decades have witnessed a revolution toward gender equality. Inequalities have been greatly reduced in areas such as education or employment. Because inequalities lead to distress, this development has largely benefited women. One notable exception is the realm of parenting, which has remained rife with inequalities even...

High levels of stress in the parenting domain can lead to parental burnout, a condition that has severe consequences for both parents and children. It is not yet clear, however, whether parental burnout varies by culture, and if so, why it might do so. In this study, we examined the prevalence of parental burnout in 42 countries (17,409 parents; 71...

Background There is inconsistent evidence for a clear pattern of association between ‘camouflaging’ (strategies used to mask and/or compensate for autism characteristics during social interactions) and mental health. Methods This study explored the relationship between self-reported camouflaging and generalised anxiety, depression, and social anxi...

Autism is more commonly diagnosed in males than females. One explanation is the ‘female protective effect’: there is something inherent in being female which reduces the likelihood of developing autism. However, evidence suggests that the condition is underdiagnosed in females, perhaps because females express their autism in ways which do not meet...

The theory of trait emotional intelligence (trait EI or trait emotional self-efficacy) is summarized with illustrative applications from the domains of clinical, educational, and organizational psychology. Key limitations of the conceptualization of EI as a cognitive ability are also briefly discussed. Trait EI is offered as a preferred alternative...

Camouflaging involves masking and/or compensating for autistic characteristics and has been identified in autistic individuals through a variety of different methods. Individual variation in the extent, processes and outcomes of camouflaging has been reported in autistic adults, and there has been some investigation of camouflaging by autistic adol...

The aim of this study was to validate the Trait Emotional Intelligence Questionnaire (TEIQue v. 1.5) in a Lebanese sample and compare its factorial structure to that of a UK sample. There were similar gender and age distributions in both samples as well as satisfactory structural reliabilities at the global, factor, and facet levels. Results from e...

Cultural, linguistic and sociodemographic peculiarities may influence trait Emotional Intelligence (trait EI). An instrument capable of assessing trait EI in different populations can foster cross-cultural research and make an important contribution to the construct's nomological network. Accordingly, the present study aimed to examine the relation...

The present study aimed to evaluate the psychometric properties of the Brazilian adaptation of the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF). In a sample of 512 participants, we tested model fit by bifactor Exploratory Structural Equation Modeling (ESEM), followed by measurement invariance testing against UK and Chilean data...

The main aim of the current study was to investigate the role of trait emotional intelligence (TEI) in preventing students' school burnout directly and indirectly via anxiety and academic resilience. The data were derived from a sample of 1235 high school students (962 females and 273 males), ranging in age between 13 and 17 years (mean = 15.46; st...

Social camouflaging describes the use of strategies to compensate for and mask autistic characteristics during social interactions. A newly developed self-reported measure of camouflaging (Camouflaging Autistic Traits Questionnaire) was used in an online survey to measure gender differences in autistic (n = 306) and non-autistic adults (n = 472) wi...

Background: Mental health literacy (MHL) is linked to help-seeking behaviours. Although lay people are not always well aware of mental health conditions, few international campaigns and interventions have been developed to raise awareness across cultures. Aims: To investigate MHL cross-culturally and to identify factors that are associated with MHL...

This study investigated the association of the five-factor model and trait emotional intelligence (trait EI) with camouflaging behaviours (masking and compensating for autistic characteristics) in a large sample of 278 autistic and 230 typically developing (TD) participants. Participants completed questionnaires assessing autistic traits, big five...

There is little doubt that currently trait EI (Trait emotional intelligence) theory and their measures have been found valid and reliable in several research and application settings. This research provides psychometric evidence of the TEIQue-SF in Chilean general and clinical population sample (n1 = 335, n2 = 120). The results confirmed the factor...

Parenting within distinct cultural contexts: a comparison across two countries and continents Parental burnout is a relatively new concept that allows researchers to understand the distress that can be experienced by individuals in the role of parents. The present study reports a cross-cultural comparison of the IIPB data collected in Chile and the...

This paper introduces Radix Intelligence, a new definition and integrative model of intelligence developed within the overarching system of Psychobionomy (Petrides, 2019). Following a discussion of misconceptions and pitfalls plaguing existing models of intelligence, with emphasis on the IQ literature, I point at Radix Intelligence as the primal en...

In this five-study paper, we developed and validated the two-dimensional Questionnaire of ethical Leadership (QueL). Drawing on previous research, we examined the factor structure of QueL using Exploratory and Confirmatory Factor Analysis, along with Measurement Invariance techniques, to data originated from more than 1200 Greek leaders and employe...

This article introduces Psychobionomy as a general system seeking to explain and utilize the laws governing the mind, which it views as the source of all life. Although its remit is a great deal wider, herein, the system is discussed with particular reference to the pressing need for new paradigms in personality psychology. I describe the basics of...

Poster summarising the validation and adaptation of the TEIQue-SF in general and clinical Chilean population.

There is little doubt that currently trait EI (Trait emotional intelligence) theory and their measures have been found valid and reliable in several research and application settings. This research tested the psychometric properties of the TEIQue-SF in Chilean general and clinical population sample (n₁ = 335, n₂ = 120). The results confirmed the fa...

Book synopsis: Interest in human emotion no longer equates to unscientific speculation. 21st-century humanities scholars are paying serious attention to our capacity to express emotions and giving rigorous explanations of affect in language. We are unquestionably witnessing an ‘emotional turn’ not only in linguistics, but also in other fields of sc...

Trait Emotional Intelligence (or trait emotional self-efficacy) is a constellation of emotional perceptions assessed through questionnaires and rating scales (Petrides et al., 2007b). This paper examined the psychometric features of the Trait Emotional Questionnaire Full Form (TEIQue-FF; Petrides, 2009b) in the Italian context. Incremental validity...

Effective strategies for increasing work motivation will consider person factors and individual differences. This article expands on the theory and construct of drive in the context of the development of a new inventory and concurrent validation of a short form. The results support the measurement of drive, which, hitherto, had not been explicitly...

Research on the role of trait emotional intelligence (trait EI; Petrides, 2001) relating to teaching performance has emerged as an important topic. The present study proposes a multilevel model of teachers’ trait EI in relation to their job performance, which simultaneously addresses the mediating role of job satisfaction and the influences of scho...

This study examines the relationship between trait emotional intelligence (trait EI) and general health (General Health; GHQ-28) in two samples of Greek parents with (n = 52; Mage = 39.78; SDage = 6.68; 41 men and 11 women) and without (n = 51; Mage = 43.53; SDage = 4.61; 40 men and 11 women) addiction problems. In addition, it compares the trait E...

Trait emotional intelligence (trait EI or trait emotional self-efficacy) is formally defined as a constellation of emotional perceptions assessed through questionnaires and rating scales (Petrides et al. Br J Psychol 98:273–289, 2007). The construct describes our perceptions of our emotional world (e.g., how good we believe we are in terms of under...

The current study evaluated the relationship between positive and negative emotions, trait emotional intelligence (trait EI) and difficulties in career decision-making. We examined whether trait EI could predict career indecisiveness, a type of career decision-making difficulty, over and above the “Big Five” personality traits. We also examined the...

A previous meta-analysis (Van der Linden et al., Psychol Bull 143:36–52, 2017) showed that the General Factor of Personality (GFP) overlaps with ability as well as trait emotional intelligence (EI). The correlation between trait EI and the GFP was so high (ρ = 0.88) in that meta-analysis that these two may be considered virtually identical construc...

The present study tested the mediating role of career adaptability on the existing relation between trait emotional intelligence (EI) and academic engagement. The sample consisted of 590 Spanish university students with a mean age of 21.66 years. The results confirmed the positive relations of trait EI with career adaptability, as well as with acad...

Camouflaging of autistic characteristics in social situations is hypothesised as a common social coping strategy for adults with an autism spectrum condition (ASC). Camouflaging may impact diagnosis, quality of life, and long-term outcomes, but little is known about it. This qualitative study examined camouflaging experiences in 92 adults with ASC,...

Camouflaging may impact diagnosis, quality of life, and long-term outcomes, but little is known about it. This qualitative study examined camouflaging experiences in 92 adults with ASC,...

Studies assessing sex/gender differences in autism spectrum conditions often fail to include typically developing control groups. It is, therefore, unclear whether observed sex/gender differences reflect those found in the general population or are particular to autism spectrum conditions. A systematic search identified articles comparing behaviour...

The conceptualisations of motivators and drive are described with emphasis on psychological measurement. Measures of motivators vary from general (multiple...

Key practitioners messages: Self-perception constructs concerning one's beliefs about oneself have a major impact on the likelihood of developing psychopathological symptoms. Emotional perceptions captured by trait emotional intelligence were stronger predictors of psychopathology than either or both mindfulness and irrational beliefs in a clinica...

This article aims to investigate the reliability and validity of the Trait Emotional Intelligence Questionnaire–Adolescent Short Form (TEIQue-ASF) score in a sample of 440 Greek adolescents. The instrument’s score demonstrated good internal consistency and was significantly correlated with core self-evaluations as well with somatic complaints, self...

The two most prominent individual differences researchers of the twentieth century were Hans J. Eysenck and Raymond B. Cattell. Both were giants of scientific psychology, each publishing scores of books and hundreds of empirical peer-reviewed journal articles. Influenced by Hebb's distinction between physiological (Intelligence A) and experiential...

This article presents an advanced application of Facet Benchmarking (FB), an instrument refinement method that sets out to identify redundant and extraneous facets (Siegling, Petrides, & Martskvishvili, 2015). FB uses external benchmarks to determine whether a measure's facets each occupy unique construct variance. In Study 1, three samples complet...

We examine the relationship between the general factor of personality (GFP) and emotional intelligence (EI) and specifically test the hypothesis that the GFP is a social effectiveness factor overlapping conceptually with EI. Presented is an extensive meta-analysis in which the associations between the GFP, extracted from the Big Five dimensions, wi...

The General Factor of Personality (GFP) is a higher-order factor causing lower-order personality traits to show consistent correlations in a socially desirable direction. The literature on the GFP reveals that there are various scientific interpretations of this construct. One interpretation is that it is a substantive factor reflecting general soc...

Introduction Cancer treatments have greatly advanced over the past two decades causing survival improvements and reduced complications from cancer surgery. However, the cancer diagnosis and the effects of treatment modalities pose a major risk to patients' psychological well-being. Given current interest and emerging evidence about the importance o...

The present study compared the psychometric properties of the Trait Emotional Intelligence Questionnaire (TEIQue) in Catalan and UK samples. The results showed similar means and standard deviations in the facets scoring higher in both languages, except for Adaptability (d: − 0.50) and emotion management (d: − 0.37). The alpha reliabilities of the T...

In this brief response, I present four thoughts on trait emotional intelligence with reference to the commentaries by Laborde and Allen (2016) and Schutte and Malouff (2016).

Trait emotional intelligence (“trait EI”) concerns our perceptions of our emotional abilities, that is, how good we believe we are in terms of understanding, regulating, and expressing emotions in order to adapt to our environment and maintain well-being. In this article, we present succinct summaries of selected findings from research on (a) the l...

This article explicates the theory of drive and describes the development and validation of two measures. A representative set of drive facets was derived from an extensive corpus of human attributes (Study 1). Operationalised using an International Personality Item Pool version (the Drive:IPIP), a three-factor model was extracted from the facets i...

Autism spectrum disorder (ASD) is characterised by profound difficulties in empathic processing and executive control. Whilst the links between these processes have been frequently investigated in populations with autism, few studies have examined them at the subclinical level. In addition, the contribution of alexithymia, a trait characterised by...

In the UK, treatment recommendations for patients with cancer are routinely made by multidisciplinary teams in weekly meetings. However, their performance is variable. The aim of this study was to explore the underlying structure of multidisciplinary decision-making process, and examine how it relates to team ability to reach a decision. This is a...
