EQ-i 2.0 Reliability and Validity
Reliability and Validity

Reliability and validity are important concepts to evaluate when selecting a emotional intelligence assessment for use in your business. Multi-Health Syetms has invested many years in EI research. What follows is a simple and easy to understand summary of the reliability and validity evidence of the EQ-i 2.0®.

What is reliability?

The reliability of an emotional intelligence assessment is often referred to as its consistency. That is, how consistent it is at measuring what it aims to measure. The two most important types of reliability for assessments are:

• Internal Consistency: refers to how well all the items of a certain scale measure the same idea

• Test-Retest: refers to how well the assessment can produce the same results over time for the same person

Overall, the EQ-i 2.0 exhibits strong reliability, both in terms of internal consistency and test-retest. This means that your clients’ scores will remain stable over time (unless development efforts are used to improve their scores) and that items measuring a certain subscale all tap into aspects of that subscale (e.g., all Empathy items are measuring the idea of Empathy).

What is validity?
Validity ensures the accuracy and usefulness of an assessment. Although there are many diff erent types of validity, they all focus on ensuring the assessment is measuring what it was designed to measure and whether it can predict important outcomes. However, it is important to understand that there is no single number to represent the validity of a test, it is assessed through the combination of several different types of validity evidence.
