PeerRev_Testing The Validity and Reliability of The Cyber Bullying Scale

The purpose of this study is to test the construct validity and reliability on the cyber bullying scale and test the forms and indicators that can construct the cyber bullying variable. Cyber bullying is measured in seven forms, such as flaming, harassment, denigration, impersonation, outing and trickery, cyberstalking, and exclusion. The populations in this study were eleventh-grade students in Vocational High Schools X, Y, and Z in Yogyakarta, with a total of 505 students. The sample in this study amounted to 100 students. The sampling technique uses cluster random sampling. The data collection method uses the cyber bullying scale. Research data were analyzed with Structural Equation Modeling (SEM) through the Smart PLS 3.2.8 program. Based on the results of data analysis, the forms and indicators that construct the cyber bullying variable are declared valid and reliable. The most dominant form that reflects cyber bullying is harassment, with a factor loading of 0.914. While the weakest form that reflects cyber bullying is cyberstalking with a factor loading value of 0.566. These results indicate that all forms and indicators are able to reflect and build cyber bullying variables. Thus, the measurement model can be accepted because the theory that describes cyber bullying variables fit with empirical data obtained from the subject
