It was Cronbach and Meehl's view of construct validity that in order to provide evidence that a measure has construct validity, a nomological network has to be developed for its measure. The elements of a nomological network are: Must have at least two constructs; Theoretical propositions, specifying linkages between constructs: "As age increases, memory loss increases". Correspondence rules, allowing a construct to be measured. Operationalization: "Age is measured by asking "how old are you?" Empirical constructs or variables that can actually be measured. These are operationalized theoretical constructs. Empirical linkages: Hypotheses before data collection. Empirical generalization after data collection.
