In order to compare relative differences in changes in moral
disengagement between the four different bullying patterns, an analysis of
variance was conducted revealing significant differences among the four
groups, F(3, 556) = 5.70, p = .001, η2 = .030. Tukey post hoc analyses
further revealed that stable bullies showed increased disengagement compared
to nonbullies (p = .032) and desisted bullies (p = .021) and that new
bullies also showed increased disengagement compared to nonbullies (p = .017) and desisted bullies (p = .021).
