In view of the typically high correlations found between various job
attitudes measured at the same point in time. these correlations are
sufficiently low as to provide some indication of an acceptable level of
discriminant validity. The percentage of common variance shared by
organizational commitment and the other measures did not exceed 50%
and was generally less than 25% for most relationships. The magnitude of
these correlations, however, are clearly higher than might be desired to
demonstrate conclusively discriminant validity, particularly when it is
considered that correlations were calculated among instruments of less
than perfect reliability.
