Psychometrics of the LEQ
The LEQ has been developed over a period of
15 years, tested on approximately 5000 individuals, and has undergone
appropriate 7 major iterations, each involving the use of factor analysis or
confirmatory factor analysis. As a result, several purported factors
(e.g., Productive Teamwork and Hardiness Resourcefulness) have been eliminated
or adjusted in order to build an instrument with identifiable factors, with
good internal consistency, and with a stable factorial structure for both
males and females and for both adolescents and adults.
The LEQ has shown good predictive validity in
that programs which aim to change particular factors have exhibited
predictable effects using the LEQ.
Currently lacking is the demonstration of
concurrent validity with other recognized measures of similar constructs.
