In this paper, we address the problem of evaluating Cronbach’s alpha (Cronbach[1]) when fake data are considered. Starting from the introduction of an integrated simulation approach, called MC+SGR, we evaluate the sensitivity of alpha to two relevant scenarios of perturbation: symmetric faking and asymmetric faking. We also report a simple example of correction table for the α statistic.

Abstract
In this paper, we address the problem of evaluating Cronbach’s alpha (Cronbach[1]) when fake data are considered. Starting from the introduction of an integrated simulation approach, called MC+SGR, we evaluate the sensitivity of alpha to two relevant scenarios of perturbation: symmetric faking and asymmetric faking. We also report a simple example of correction table for the α statistic.
