Reliability and Validity
The TEIQue instruments and materials are among the most extensively validated psychological assessments available today. They are continually updated based on our research at the LPL.
Please do not e-mail to request information about the reliability and validity of the TEIQue - your own study provides such data. In the trait EI publications page, there are numerous publications from the research program that present TEIQue data. Any of these can be cited as evidence of construct validity. All of these studies also present detailed information on internal consistency. In addition, there are scores of studies in the scientific literature utilizing the TEIQue. For a partial bibliography, click here.
With respect to internal consistency, it should be kept in mind that it is a property not of tests, but of test scores (see Thompson, B. & Vacha-Haase, T. (2000). Psychometrics is datametrics: The test is not reliable. Educational and Psychological Measurement, 60, 174-195). It is not meaningful simply to declare that an instrument is reliable or psychometrically robust. Each TEIQue study contributes information relevant to internal consistency and validity.
A general reference that can be used for all TEIQue instruments is:
Petrides, K. V. (2009). Psychometric properties of the Trait Emotional Intelligence Questionnaire. In C. Stough, D. H. Saklofske, and J. D. Parker, Advances in the assessment of emotional intelligence. New York: Springer. Doi: 10.1007/978-0-387-88370-0_5 [pdf] See also the TEIQue technical manual.
If you have conducted a peer-reviewed study using any TEIQue instrument, please send us a reprint. Please also send us e-copies of dissertations, especially if you believe you have obtained anomalous results.
