4.2 Research model validation
To assess the internal consistency of research concepts, the Exploratory Factor Analysis (EFA) method and the Cronbach Alpha reliability coefficient method were performed.
4.2.1 Cronback Alpha Test
Cronbach's Alpha coefficient analysis is used to evaluate the reliability of the scale in the study. The criteria for selecting a scale must have a reliability of 0.6 or higher and variables with a total item correlation coefficient of less than 0.3 will be eliminated.
