Validation of the Peruvian version of the Wong and Law Emotional Intelligence Scale (WLEIS-P)

Introduction: Research has confirmed that emotional intelligence (EI) is an important theoretical and empirical construct associated with psychological well-being and physical and mental health. One of the most used EI assessment instruments in research is the Wong and Law Emotional Intelligence Scale. This study aims to analyse the psychometric properties of the Peruvian version of the WLEIS-P scale. Method: The sample consisted of 2,574 adults: 1,859 were women (72.2%), and 715 were men (27.8%). The age of the participants ranged between 18 and 30 years (M = 20.83, DT = 2.46). Participants completed a test battery that included the WLEIS-P and a subjective well-being scale. Results: The results showed a four-factor structure with a good fit, adequate internal consistency, and convergent validity in line with the original instrument and the adaptations made in other contexts. Conclusion: Finally, the results confirmed scalar invariance for both sex and age. In summary, our results provide evidence that the WLEIS-P could be a helpful tool for evaluating emotional intelligence in the Peruvian adult population.
