The Bayer Activities of Daily Living Scale (B-ADL) has been developed
on an international basis to assess deficits in the performance of eve
ryday activities. The scale's main target group is community dwelling
patients who suffer mild cognitive impairment or mild-to-moderate deme
ntia. It comprises 25 items and takes the form of a questionnaire to b
e completed by a caregiver or other informant sufficiently familiar wi
th the patient. Statistical, clinical and domain-related criteria were
used to select items from among a large number of activities of daily
living (ADL) questions field tested in pilot studies in the USA, Germ
any, UK, Russia and Greece. The items included in the B-ADL have been
chosen for their sensitivity to cognitive impairment, simplicity of co
ncept, international applicability and their relevance to patients cop
ing with the demands of everyday life. The scale uses items which refl
ect a wide range of domains. On account of its brevity, it is thought
especially suitable for application within a GP and primary care conte
xt for. both screening a patient's ADL capacities as well as for docum
entation of treatment effects and the progress of dementia. This paper
focuses on a description of the scale and its application.
