Validity

Hello, I believe you can talk about Gender difference in the last section Is Gender Diagnosticity a Useful Construct for Psychologists to Measure? Why and Why Not?

In that part, we talked about that Gender Diagnosticity approach is stable although masculinity and femininity sometimes present themselves differently in different time periods, groups and cultures, so you can add how gender differences across culture and how it may influence the validity of Gender diagnosticity by giving an example before the first paragraph. Hope this can help you ;)
