This study sought to develop and validate an instrument measuring cyberbullying among
Malaysian youths. Exploratory factor analysis (EFA) was employed to determine the best
sub-factors and items for the instrument, while confirmatory factor analysis (CFA) was
performed to test and validate the measurement model. Results from EFA on 38 items
showed that the items were pooled into four sub-factors. Meanwhile, results from CFA
indicated that eight items had to be discarded in order to confirm that the model was fit.
Overall, the final version of the instrument consisted of four cyberbullying sub-factors,
namely, impersonation (13 items), cyberstalking and harassment (nine items), flaming (four
items), and elimination (four items).
