[Validation of Guttman scales of vigor and readiness to make social contacts in the aged].
Two Guttman-scales for the assessment of functional health and sociability of aged persons were examined in several different samples concerning their scalability, dimensionality, and validity. They proved well suited for a relatively broad use. Contrary to other measures of ADL-functioning, our functional health scale discriminates the upper levels of functional competence. In regard to expert-ratings as well as to measures of actual behavior, both scales proved to be valid. The functional health scale correlates significantly with the Barthel Index but shows a better sensibility for changes of functional competence during a half-year period.
