In order to identify individuals at risk for frailty, a wide variety of assessment tools have been developed in recent years. Nevertheless, there is still a lack of a gold standard method to be used. Therefore, simple, reliable, and valid instruments are still needed for both research and clinical purposes. The Kihon Checklist is a multidimensional tool widely used in Japan and in other countries, but an exhaustive validity in Spanish population has not been yet established.~The main objective is to validate the Spanish version of the Kihon Checklist for screening frailty in Spanish community-dwelling older adults, and as a secondary objective, to study and to compare different scales of frailty in the Spanish population, and to study their associations.~To cope with the objectives of the present study, a cross-sectional study was conducted. To this purpose, data were collected through various tests and questionnaires about: frailty; clinical, demographic and anthropometric characteristics; physical assessment; functional status; cognitive function; health-related quality of life; depressive mood; and nutritional status.
The purpose of this cross-sectional study is to validate the Spanish version of the Kihon Checklist for screening frailty in Spanish community-dwelling older adults.
