I suggest you do a simple correlation analysis between these indicators to see if there is a certain correlation between these indicators. Only when there is a certain correlation is it suitable for factor analysis.

If there is no correlation, these indicators themselves are not suitable for factor analysis. Of course, it can also be said that each of these indicators represents a factor and does not need to be re-concentrated.

In addition, during the factor analysis, a project will output which KMO and Bartley ball tests to see if the tests can be used for factor analysis.
