Validating and measuring IC in the biotechnology and telecommunication industries

This paper specifies how to construct and validate an intellectual capital (IC) measurement scale on the basis of management perceptions. In order to construct the scales, a process based on the works of Churchill and DeVellis, complemented by the Delphi technique and structural equations models was used. The use of this methodology was illustrated in an empirical study carried out in the biotechnology and telecommunication sectors. As a result, a validated instrument for IC research is obtained in view of the faithful and rigorous measurement of its key construct.
