Answer to Question 1

B
Feedback:
An instrument's content validity is based on the judgment of experts evaluating the instrument, which is the case here. There is no totally objective method for insuring adequate content coverage, but often a panel of subject content experts is asked to evaluate the content validity of new instruments. Researchers can calculate a content validity index (CVI) that indicates the extent of expert agreement. Internal consistency is a measure of the extent to which all of an instrument's items measure the same thing. Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument. Face validity refers to whether an instrument looks as though it is measuring the appropriate construct.
