<scp>Kihon Checklist</scp> to assess frailty in older adults: Some evidence on the internal consistency and validity of the <scp>Spanish</scp> version

Aim The aim of this study was to assess the internal consistency, hypothesis testing and criterion-related validity Spanish versions Kihon Checklist (KCL) – original 25-item reduced 15-item for screening frailty in community-dwelling older adults. Methods A cross-sectional carried out between March September 2018 Valencia province (Spain). sample 251 participants recruited. Construct assessed using four different instruments, alternative measures corresponding KCL domains (handgrip strength, gait speed, Short Physical Performance Battery, skeletal muscle mass index, physical activity level, functional status, cognitive function, depressive mood, health-related quality life nutritional status). Fried's Frailty Phenotype used evaluate criterion validity. Results Internal consistency with Kuder–Richardson Formula had a value 0.69 version, slightly lower than usual 0.7 considering good reliability, 0.71 version. There were significant correlations Phenotype, Edmonton Scale, Tilburg Indicator FRAIL Scale. Consistent also obtained all measurements instrumental activities daily living, eating, socialization, mood KCL. closely correlated other standardized life. showed satisfactory diagnostic accuracy (area under curve 0.891 KCL-25; area 0.857 KCL-15). optimal cut-off points 5/6 3/4, respectively. Conclusions findings suggest that both KCL, especially KCL-15, adequate evidence as preliminary among adults Spain. Geriatr Gerontol Int 2021; 21: 262–267.
