In this study, we aimed to analyze the psychometric properties of the WLEIS-S Scale and generate normative data for measuring emotional intelligence in the Peruvian context. A total 782 people participated, 175 men (22.4 %) and 607 women (77.6 %), between 18 and 59 years old (M=29.39, DE=9.67), selected through a non-probabilistic convenience sampling. First, the metric quality of its 16 items was verified. Then, its internal structure was analyzed through confirmatory factor analysis, finding adequate fit indices for the bifactor model: χ2=305.795, CFI=.969, TLI=.958, RMSEA=.056 y SRMR=.029, in addition to evidence in favor of its unidimensionality: PUC, ωh and H coefficient >.80, ECV >.60 and explained variance of 71.97%. Likewise, evidence of its discriminant validity was found in relation to the scores of psychological discomfort measured with the K10 Scale (r=-.37, r2=.13). ...

Esta investigación tuvo por objetivo analizar las propiedades psicométricas y elaborar datos normativos de la Escala de Inteligencia Emocional de Wong-Law (WLEIS-S), utilizando una muestra de 782 adultos de Lima Metropolitana, con edades entre 18 a 59 años, seleccionados mediante el muestreo no probabilístico por conveniencia. El análisis de la estructura interna mediante el AFC evidenció índices de ajuste óptimos para el modelo bifactor (X =305.795, CFI=.969 y TLI=.958, RMSEA=.056, SRMR=.029) con indicadores adicionales a favor de la unidimensionalidad (PUC, coeficiente omega jerárquico y H >.80, ECV >.60 y varianza explicada de 71.97%). En las evidencias de validez en relación con malestar psicológico medido con la escala K10 se confirmó una relación inversa y tamaño de efecto medio (r=-.37, r 2 =.13). Se evaluaron las evidencias de fiabilidad por el método de consistenc...

The growing scientific literature on Emotional Intelligence (EI) has evidenced the development of different models and evaluation instruments to measure this construct. The objective of this research was to identify the best instruments available to measure emotional intelligence, and to clarify the relationships of this construct with other relevant variables in the adult population, based on a systematization of the scientific literature produced in the last decade. The search was carried out in indexed journals from the Scopus, Scielo, EBSCO, ProQuest and Redalyc databases between 2012 and 2022, and a sample of 74 articles was found. Among the main findings, 13 instruments will have adequate evidence of validity and reliability. In addition, emotional intelligence was related to 49 variables, and in most studies it was associated with sex. In conclusion, the most recommended instrumen...
