Authors used a multiple comparison method to further analyze the items where significant
differences existed among the means between the subsequent tests.
On item Q1.1 (understanding of the role and impact of individuals on the success or failure
of a change process), the mean of the second test was significantly lower than that of the first and
the fourth test (p
