Rehabilitation researchers have found in the application of the Delphi method a more sophisticated way of obtaining consensus from experts in the field on certain matters. The application of this research methodology has affected and certainly advanced the body of knowledge of the rehabilitation counseling practice. However, the rehabilitation literature has not yet described conceptually the Delphi methodology. The purpose of this article is to present a description of the Delphi method and to discuss some advantages and disadvantages of using this research technique. In addition, the authors present the results of four studies, identified in the rehabilitation literature, that used the Delphi method.
