Relationship between Emotional Intelligence and Personality
An interbattery factor analysis of the Emotional Quotient Inventory and the Work Personality Index
Stream three or mixed model emotional intelligence (EI) measures have been shown to be correlated with personality in the research literature. The objective of this study was to further examine the nature of this relationship. Previous studies using joint factor analysis to investigate the relation between personality and mixed model EI have located EI as a separate trait in personality factor space. A common problem with using joint factor analysis for this purpose is the possibility of method artefacts. Thus, joint factor analysis may not reflect the true relationship between two variable sets. In the present study, an interbattery factor analysis was conducted with the scales of the Emotional Quotient Inventory (EQ-i) and the Work Personality Index
(WPI). Interbattery factor analysis identifies only common factors between two variable sets. The sample size consisted of 615 working adults who completed the assessments for selection or developmental purposes. After a direct quartimin rotation, an eight factor solution provided the most parsimonious and theoretically meaningful solution. The analysis identified seven common factors between the EQ-i and WPI. Only Teamwork from the WPI loaded on factor eight. In contrast to previous results, EI did not load separately in personality factor space. The common factors between these variable sets indicate that the different constructs measured by EI and personality are related. Some of the relationships identified among the variables were unexpected. This provides additional interpretive information for when the EQ-i and WPI are used in conjunction.
JVR will be presenting their research on the relationship between emotional intelligence and personality using an interbattery factor analysis of the Emotional Quotient Inventory and the Work Personality Index at the International Congress of Psychology in
Cape Town, South Africa on July 22-27, 2012.
This research provides additional interpretive information for when using the EQ-I and WPI in conjunction.
