Construct validity refers to whether a [[scale (social sciences)|scale]] measures the unobservable [[social construct]] (such as "[[fluid intelligence]]") that it purports to measure. The unobservable idea of a unidimensional easier-to-harder dimension must be "constructed" in the words of human language and graphics. A construct is not restricted to one set of observable indicators or attributes. It is common to a number of sets of indicators. Thus, "construct [[Validity (statistics)|validity]]" can be evaluated by [[statistics|statistical methods]] that show whether or not a common factor can be shown to exist underlying several measurements using different observable indicators. This view of a construct rejects the operationist past that a construct is neither more nor less than the operations used to measure it.

There are variants of [[construct validity]]. They are [[convergent validity]], [[discriminant validity]], and [[nomological validity]].
