Sometimes. The TEIQue-SF measures trait emotional intelligence: people’s self-perceptions about their usual emotional dispositions. In one Swedish employee study, it added statistical information about self-rated task performance beyond age, gender, neuroticism, and conscientiousness. The same study found an association with self-rated contextual performance, but that model did not control for personality traits. A broader meta-analysis found a modest average increment across varied outcomes, not work behavior alone. The evidence makes TEIQue-SF a possible prompt for reflecting on perceived patterns, not a dependable forecast of what colleagues will observe.
What does TEIQue-SF measure, and what does “beyond personality” mean?
The TEIQue-SF is a self-report questionnaire for trait emotional intelligence (trait EI), a construct defined as emotion-related self-perceptions and dispositions. It asks about how people generally see their emotional functioning. It does not test how accurately someone solves emotion problems under controlled conditions. Trait EI is deliberately located within the personality domain, so overlap with broad traits is expected, not a flaw that can be removed by calling it a separate ability. The Swedish validation paper reports that Big Six personality traits explained 48% of variation in its global trait-EI score. [The authors describe the construct and sample here](https://link.springer.com/article/10.1007/s12144-020-00753-w).
“Beyond personality” has a narrower statistical meaning. Incremental validity is the extra variation in a chosen outcome accounted for by a measure after specified predictors have already been entered in a model. It does not mean that the measure is independent of personality, that it causes the outcome, or that it predicts every kind of work behavior. The comparison is only interpretable when we know the exact outcome and which traits were controlled. A self-rated emotional tendency that adds to a self-rated work outcome may tell us about a person’s view of their work pattern; it does not automatically tell us what a supervisor would see.

What work evidence does the TEIQue-SF add?
The broadest evidence is a 2015 systematic review and meta-analysis of adult TEIQue research. It reviewed 24 articles with 114 incremental-validity analyses and pooled 18 studies, representing 105 effect sizes. Across varied areas of functioning and predictor sets, the pooled added variance was ΔR² = .06, with a 95% confidence interval from .03 to .08. The authors said contributions were mainly associated with trait EI’s well-being and self-control factors. That is a modest average across mixed criteria, not an estimate of how well TEIQue-SF predicts workplace conduct in particular. [The UCL record provides the study count and pooled result](https://discovery.ucl.ac.uk/id/eprint/1475183/).
The direct workplace test in the plan’s evidence is a cross-sectional survey of 228 people working in multiple occupations in Sweden. Respondents completed the Swedish TEIQue-SF, personality measures, and a self-report measure of individual work performance. In hierarchical regression, adding the global TEIQue-SF score increased explained variation in self-rated task performance by six percentage points after age, gender, neuroticism, and conscientiousness were considered. That is the clearest direct evidence here that TEIQue-SF can add information beyond personality about a defined work outcome.
The contextual-performance result needs a different description. This outcome concerns perceived contributions around core tasks, such as helping work proceed. TEIQue-SF increased explained variation by 17 percentage points after age and gender, but no personality variable met the study’s corrected screening criterion for that model. So the result cannot be described as an increment beyond personality. The measure added information beyond demographics in this analysis. It added no variation for self-reported counterproductive work behavior. These distinctions come from the study’s regression results and are reported in its [full article](https://link.springer.com/article/10.1007/s12144-020-00753-w).

Why doesn’t statistical increment settle the question about behavior?
All measures in the Swedish study were collected by asking participants to rate themselves, at one point in time. The authors therefore tested whether one set of self-perceptions explained differences in another, not whether TEIQue-SF scores forecast future conduct observed by coworkers. A person who sees themselves as emotionally steady may also rate their own task performance favorably; both answers can reflect a shared perspective. The study’s cross-sectional design also cannot show that trait EI caused the performance ratings. Its authors describe the sample as relatively young and highly educated, with many participants working while studying, and call for tests in more heterogeneous groups.
A 2023 study of 314 professionals across seven occupations in Kuwait offers a useful boundary, though it asks a different comparison. It tested whether trait EI added to job satisfaction and organizational commitment, not to Big Five personality. The added prediction of a single self-rating of job performance was significant among engineers and police officers, but not among bankers, healthcare providers, lawyers, military personnel, or teachers. Participants rated their own performance with one question, and profession groups were small. This does not contradict the Swedish result: it uses a different predictor set, population, language adaptation, and outcome. It does show why one increment should not be generalized across occupations. [The Frontiers study reports its sample, measure, and profession-specific results](https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2023.1051558/full).
A Canadian study adds evidence that the short form can contribute beyond the Big Five on emotion-relevant criteria, but it does not close the workplace gap. Across two university-student samples, TEIQue-SF predicted all seven criteria examined; all variables were self-reported, and the authors called for further research, including criteria measured by methods other than self-report. Its findings support incremental capacity in those samples, not a claim about employees’ observed behavior. [The published study describes both samples and this limitation](https://www.csmh.uwo.ca/docs/publications/Siegling%2C%20Vesely%2C%20Petrides%2C%20and%20Saklofske%202015.pdf).

When is TEIQue-SF useful for your own work reflection?
The evidence supports a qualified yes: TEIQue-SF may add a useful angle on some defined, self-reported outcomes, but direct work evidence is limited and does not establish general prediction of observed behavior. It is most defensible as a prompt when the question is how you perceive your own emotional patterns. Treat any answer as a hypothesis to compare with a specific event, not as a second personality verdict.
For example, after a disagreement, note what you thought you felt, how you interpreted the other person’s response, and what you did next. Then compare that account with a concrete consequence or specific feedback from someone who was there. This is a practical reflection method, not an outcome tested by the studies above. It keeps the questionnaire’s self-perception in view while grounding a development choice in an observable exchange.
EQ Test’s 32-item Emotional Skills Profile is a separate educational reflection tool for examining recent habits and judgments about authored scenarios; it is not the TEIQue-SF, has no validated norms or established ability-test validity, and does not predict job performance. If you want a private way to reflect on emotional skills and choose an observable practice priority, [explore the Emotional Skills Profile](/assessment). The answer to the opening question is therefore conditional: TEIQue-SF can add statistical information for some outcomes, but whether it adds useful information about your work depends on the outcome, comparison, and whether it helps you examine a pattern you can check in real interactions.

From this guide: A TEIQue-SF score can describe self-perception, while your next useful question may be what you actually do in a tense conversation.
The private 32-item Emotional Skills Profile offers a separate way to reflect on recent emotional habits and scenario judgments, then identify a practical development priority. Use it to choose one behavior to notice in a real conversation, such as how you respond to feedback or set a boundary. It is an educational reflection tool, not a norm-based score or forecast of work performance.
