The survey was developed comprises 2 sections consisting of 40 items. A total of 21 responses were received. The RMM is used to measure the quality control of item dimensions in the instrument. As a result, almost all the items in the questionnaire constructs were statistically reliable and valid for further analysis, and a few items need to be revised and changed. This specifies that the respondents are reliable and the items are reasonable for this study.
