Internal consistency was used as the approach in measuring reliability. Each assessment was meant to be administered multiple times to skilled practitioners to rate organizations with which they had been associated. During each assessment's development, the internal consistency of each construct was measured using Cronbach's coefficient alpha, which is the most common statistic used to quantify the degree to which all items within a given construct measure the same attribute. Based on a review of scholarly literature, a minimum alpha level of 0.7 was applied. Only items that were included in the final alpha calculation are included in the instrument. The range across all constructs of the performance improvement maturity assessment was between 0.8147 and 0.9085. The range across all constructs for the change-readiness assessment was between 0.8212 and 0.9085 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/28 UR - accessmedicine.mhmedical.com/content.aspx?aid=1150286944 ER -
