Examining construct validity and reliability of the aggressiveness scale

The purpose of this study is to test the validity and reliability of aggressiveness construct and test the forms and indicators that form this variable. Aggressiveness is measured by two forms, namely hate or anger and instrumental aggression. The population in this study are all teenagers in the city of Yogyakarta. The sample in this study are 60 teenagers in the city of Yogyakarta. The sampling technique is accidental sampling. The data collection method used is aggressiveness scale. Research data were analyzed with Structural Equation Modeling (SEM) through the SmartPLS 3.2.8 program. Based on the results of data analysis, the forms and indicators that make up the aggressiveness variable are declared valid and reliable. The most dominant form that reflects the aggressiveness variable is instrumental aggression with a loading factor of 0.934. The weakest form which reflects the aggressiveness variable is hate or anger with a loading factor of 0.851. This shows that all forms and indicators are able to reflect and form variable aggressivens. Thus the measurement model can be accepted because the theory that describes the variable fit with empirical data obtained from the subject
