ANS: B
In examining the validity of the new instrument, it is important to determine how closely the existing instruments measure the same construct as the newly developed instrument (convergent validity). Divergent validity would measure the differences in measurement, between an existing instrument and a newly-developed one. Discriminant analysis measures the difference between two related but not identical concepts. Content validity is the extent to which a measurement represents the concept being measured.
