Comparative Study
[Test-retest reliability of a German language multidimensional assessment instrument in elderly probands].
Most geriatric assessment instruments have been developed in the English language. Translated versions might differ in their psychometric properties. We analyzed the test-retest reliability and internal consistency of a German instrument for multidimensional geriatric assessment that was based on a newly developed English version. ⋯ Cronbach alpha (internal consistency) was good to excellent for all domains (0.76 < or = alpha < or = 0.95). The study results confirm good test-retest reliability of the German version of this multidimensional geriatric assessment instrument. Adapted versions of this instrument can be used for different purposes, e.g., preventive home visits, outpatient geriatric assessments or epidemiological studies in older persons.
