learn to make a personality test

I have read the book.
Scale Development – Theory and Applications Second Edition

So now I know about factor analysis
and item reponse theory (IRT)

And I have gotten two book recommended

“Handbook of Test Development,” edited S. M. Downing and T. M. Haladyna.

And Mark Wilson’s new textbook, “Constructing Measures: An Item Response Modeling Approach.”
