Hypothesis 1 (The use of negative emotion regulation strategies increases
the effect of anger on cyberbullying behavior) was partly supported:
although no effect was found at wave 3 and across waves, the
interaction effect was significant atwave 1 and 2. Negative emotion regulation
reinforced the effect of anger on cyberbullying behavior. Since
the effect was not found longitudinally, this indicates that negative
emotion regulation possibly only affects the association between
anger and cyberbullying at a short period of time, but not on the longer
run.
