*4.1. Confidence and Validity Analysis*

Reliability research methods are often used when analyzing research projects to test whether they are reasonable and meaningful (Table 4). Validity analysis is performed using factor analysis methods to verify the validity level of the data with KMO values of commonality, variance explained values, factor loading coefficient values, and other indicators. KMO values are used to select the suitability of the fact extraction, and commonality values are used to eliminate unreasonable items (Table 5).
