Dimensions underlying frailty indicators in the Kihon Checklist.

This work constitutes the first study on the dimensionality of the KCL and the first validation of the Spanish version in a Spanish sample of community-dwelling older adults. A translation exists into Spanish, but there are no data on the reliability and validity of the KCL for its use in Spanish-speaking countries. The KCL, once depurated, offers a valid and reliable measure of frailty to be used in Spanish-speaking populations. Geriatr Gerontol Int 2019; 19: 982-987.
