Analysis results: Reliability analysis and testing show that both the independent and
dependent variables meet the criteria for reliability and relevance. Specifically:
Test for Model Suitability and Correlation
The research team conducted Exploratory Factor Analysis (EFA) for both the
independent and dependent variables. The results are as follows:
Table 4. Results of the suitability and correlation test of the EFA analysis model for
independent factors.
KMO and Bartlett's Test

Kaiser-Meyer-Olkin Measure of Sampling Adequacy. .686

Approx. Chi-Square 3513.174

Bartlett's Test of Sphericity df 300

Sig. .000

Source: From SPSS
The KMO measure has a value of 0.686, satisfying the condition: 0.5 ≤ KMO ≤ 1; the
Bartlett’s test shows a significance level of Sig = 0.000 < 0.005. Therefore, the Exploratory
Factor Analysis (EFA) is suitable for the research data.
