Three scales measuring decision maker evaluations of decision aids and information provision formats were evaluated. The scales measured perceived decision accuracy, effort put into the decision process, and difficulty experienced during the decision process. Psychometric analyses indicated the scales were unidimensional, reliable, and exhibited evidence of nomological validity. The scales were, therefore, recommended to researchers and information providers studying the efficacy of decision aids.
