Construct and concurrent validity of the short- and long-form versions of the trait emotional intelligence questionnaire

This study tested the concurrent validity of the short-form version of the trait emotional intelligence questionnaire (TEIQue-SF) against the long-form version (TEIQue-LF), and the construct validity of each questionnaire. 

In total, 1889 Spanish adults (935 women, 954 men; mean age = 21.56 years, age range = 18-37 years) completed the TEIQue-SF and TEIQue-LF, the order of which was counterbalanced across participants. 

Confirmatory factor analysis supported the 4-factor structure of both the short-form and long-form versions, with marginally stronger factor loadings observed for the long-form. Bivariate correlations demonstrated a high degree of similarity in scoring on the TEIQue-SF and TEIQue-LF for each subscales and the global trait emotional intelligence (EI): well-being (r = 0.76), self-control (r = 0.69), emotionality (r = 0.78), sociability (r = 0.71), and global trait EI (r = 0.83). 

Overall, findings indicate that the TEIQue-SF is a viable alternative to the TEIQue-LF for research in time-restricted conditions where the completion of long questionnaires might be unfeasible.
