Methods settled to test the validity of a study are very subjective, even if some of them seem to be more "scientific", being based on the principle of correlation. However the last-mentined don't stand up to some theoretic weakness and other explicit subjective methods should be chosen instead : for instance experts consensus.Methods of reliability evaluation have been developed under strong hypothesis to estimate a reliabilit…
