Development of a healthcare quality improvement measurement tool: results of a content validity study.

Current methods of measuring continuous quality improvement (CQI) implementation are too long and not comprehensive. A new survey for CQI implementation was developed and tested for content validity using a panel of 8 experts--7 from the United States and 1 from England. The survey was reduced from 70 items to 22. The resultant survey had a clarity interrater agreement (IR) of .91, a representativeness IR of .93, a clarity content validity index (CVI) of .73, and a representativeness CVI of .91. Content validity served as an excellent data reduction method in building a valid, concise, and comprehensive measure of CQI implementation.
