The psychometric properties of the Emotional Quotient Inventory 2.0 in South Africa

Abstract

Orientation: Psychological assessments require continued refinement, updating and evaluation.

Research purpose: The purpose of this study is to examine the psychometric properties of the Emotional Quotient Inventory (EQ-i) 2.0 in South Africa. Item response and classical test theory methods are employed to investigate its item functioning and factor structure.

Motivation for the study: Although there has been some scientific research published on the EQ-i in South Africa, there has been no research on the revised version, the EQ-i 2.0. In addition, criticism has been levied against the estimation of internal consistency reliability in the field of emotional intelligence. This study aims to fill these gaps in the literature.

Research design, approach and method: This study followed a quantitative, non-experimental,cross-sectional design using secondary data. The sample comprised 1144 working adults(570 men and 574 women). The data were collected through an online platform as part of the standardisation process in South Africa.

Main findings: Results from Rasch analysis showed that almost all the items fit the model.Cronbach’s alpha and McDonald’s omega estimates revealed satisfactory reliabilities.Confirmatory factor analysis at the composite level revealed acceptable fit with the exception of the total EQ model.

Practical/managerial implications: This study supports the claim of reliability and validity ofthe EQ-i 2.0 in the South African context.

Contribution/value-add: The study contributes significantly to the international body of evidence regarding the psychometric properties of the EQ-i 2.0 and provides supporting evidence for the appropriate use of this assessment in South Africa.
