The authors, both ICIQ committee members, debated the title. If the conceptualization of the ICIQ is correct, the PROs recommended by the ICIQ need to be under constant evolution and improvement to ensure the aims of the ICIQ project. A modular questionnaire design, recognized and implemented internationally, would add greatly to the universal inclusion, interpretation and understanding of PRO data in clinical practice and clinical research. However, in order to achieve the goals of the ICIQ project, we must ensure that the scientific quality of PRO development, documentation and validation meets current scientific standards, as well as societal and governmental regulatory guidelines. These topics are discussed along with recommendations for future areas of research and need for the ICIQ committee to explore these issues.
