Representation validity

Representation validity is concerned about how well the constructs or abstractions translate intoobservable measures. There are two primary questions to be answered.
*Do the subconstructs properly define the construct (if you break up the main abstractions intosmaller abstractions or definitions)?
*Do the observations properly interpret, measure, or test the constructs?

One way to argue positively, albeit a very weak argument, is to claim face validity for theconstruct/observable relationship. Basically this is making the following claim: on the face of it,it seems like a good translation. The weakness of this argument can be strengthened by aconsensus of experts.Another way to argue positively is to claim content validity for the construct/observablerelationship. To do this one must check the operationalization against the relevant contentdomain for the construct: to extent to which the tests (ie, the observable measures) measure thecontent of the subject being tested — ie, that all the important content areas are coveredadequately.
