Size selective inclusion of organic molecules into pillared carbons accompanied by large interlayer expansions was observed for the first time. In order to achieve this, the distance between two adjacent pillars should be between 0.36 and 0.40 nm and they should align in the same direction.
Aims: To establish the reliability and validity of a performance evaluation tool based on the modified Barthel Index (PET-MBI) for elderly residents of long-term care facilities. Methods: To develop the PET-MBI, the 10-task modified Barthel Index was translated into Japanese by three therapists, taking Japanese culture and lifestyles into account. Its reliability was independently assessed by two therapists who evaluated 16 participants (mean age 85.6 years; standard deviation (SD)=7.3) from one facility. The internal consistency and validity of the PET-MBI was then assessed by two therapists at three facilities, who evaluated a total of 110 participants (mean age 85.0 years; SD=7.1). Findings: We excluded the item ‘stair climbing’ because participants did not have to do this. Kappa coefficients of intra-tester reliability based on the test-retest method were 0.70–1.00 for individual tasks of the PET-MBI; kappa coefficients for inter-tester reliability were 0.72–1.00. Cronbach's coefficient alpha of internal consistency was 0.93. Factor analysis according to the PET-MBI revealed that a single factor explained self-care in elderly residents. Conclusions: The PET-MBI demonstrated high reliability, validity and internal consistency for the assessment of elderly residents in facilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
