Evaluation of Hall's Professionalism Scale for professionals in the construction industry

Hall's conceptualisation of professionalism, among other studies, was considered the most representative modern concept; his scale has been studied widely. This study aimed to evaluate empirically the Snizek modified version of Hall's Professionalism Scale for building professionals. The scale was tested in a cross-section of 510 qualified building professionals selected from four countries. Using a cross-national electronic questionnaire survey, a series of statistical analyses were conducted to evaluate the Snizek's modification. Analysis suggested that data for scale validation are consistent in confirming it is a five-factor scale; however, the scale should be subjected to a further refinement before it can be used in research.
