What is the Ability Emotional Intelligence Test (MSCEIT) good for? An evaluation using item response theory

Area of Science:

• Psychology
• Intelligence Measurement
• Emotional Intelligence Research

Background:

• The ability approach is a promising framework for advancing emotional intelligence (EI) research.
• A significant scarcity exists in validated tests measuring EI as a distinct form of intelligence.
• The Mayer Salovey Caruso Emotional Intelligence Test (MSCEIT) is a widely used measure of EI ability.

Purpose of the Study:

• To evaluate the psychometric properties of the MSCEIT, specifically its ability to measure high EI.
• To determine if expert-endorsed correct answers on the MSCEIT correlate with high EI ability.
• To assess the MSCEIT's effectiveness in discriminating between individuals across the EI spectrum.

Main Methods:

• Examined the relationship between item response patterns and EI ability levels on the MSCEIT.
• Assessed whether individuals with the highest probability of selecting expert-agreed correct answers also possess the highest EI.
• Analyzed item difficulty and discriminatory power for individuals with varying EI.

Main Results:

• For many MSCEIT items, the expert-defined correct answer was not associated with the highest EI ability.
• Several items on the MSCEIT appear too easy, failing to adequately challenge individuals with high EI.
• The MSCEIT demonstrates a greater capacity to differentiate individuals at the lower end of the EI spectrum.

Conclusions:

• The MSCEIT's validity for measuring high emotional intelligence is questionable.
• The test's current structure may limit its utility in distinguishing high EI individuals.
• Findings suggest the MSCEIT is more effective at identifying individuals with lower EI, impacting theoretical and applied EI research.
