Foley catheterization (FC) is known to result in complications. Validated checklists are central to teaching/assessing procedural skills and may result in improved health care quality. The results of the first step of the validation of male and female FC checklists are described. A comprehensive literature review of articles published on FC did not yield a checklist validated by the Delphi method. A modified Delphi technique involving a panel of 7 experts was used to develop FC checklists. The internal consistency coefficients using Cronbach's α were .91 and .88, respectively, for males and females. Developing a 24-item male FC checklist and a 23-item female FC checklist for teaching/assessing FC is the first step in the validation process. For these checklists to become further validated, they should be implemented and studied in the simulation and the clinical environments.
