An empirical basis for domains in the analysis of dependency in the activities of daily living (ADL): results of a confirmatory factor analysis of the Cleveland Scale for Activities of Daily Living (CSADL).

This study examines the empirical basis for dividing activities of daily living (ADLs) into broad behavioral domains. Following an exploratory factor analysis of results from the Cleveland Scale for Activities of Daily Living (CSADL), a two-factor model of ADLs was tested in a confirmatory factor analysis using two groups of demented patients. The model, which included a Basic and an Instrumental factor, was confirmed.
