Note: Principle Component Analysis was completed to determine if questionnaire items should be grouped or single. Some questionnaires (the NMIBC24 and C30) have both grouped domains and single items. The BCI is the only BCSI which has individual scores for each domain. See definition of Principal Component Analysis in Appendix 1.
