Full description

Dementia refers to a condition in which individuals with brain damage have multiple cognitive deficits with impairment in activities of daily living (ADL). Therefore, the assessment of ADL is one of the main criteria for evaluating dementia. ADL disorders are often observed by caregivers before they are identified by psychometric testing, thus suggesting that ADL assessment can contribute to the early detection of dementia.

Evaluation of ADL has become increasingly important with the introduction of new drugs for Alzheimer's disease (AD), as well as being a helpful tool in diagnosis. Current guidelines have recognized the need for therapeutic intervention in AD to measure and document treatment effects on ADL. It has been emphasized that internationally validated and approved test tools to evaluate dementia are important for multinational clinical drug trials that evaluate the efficacy of anti-dementia drugs. Therefore, it is of great importance to find ADL scales that can be used internationally. Various ADL scales have been developed, such as Lawton's instrumental ADL (IADL), functional activities questionnaire (FAQ), ADCS-ADL, and Bayer ADL (B-ADL). Of these, W-ADL was developed based on an international pilot study to evaluate ADL deficits in patients from different cultural backgrounds.

Specifically, through a collaborative study conducted in four different countries during the development of the RDA, the researchers prepared 141 items and selected 25 of them that could be used internationally. The target group of the scale included elderly patients suffering from mild to moderate dementia or cognitive impairment. European countries: In the United Kingdom, Germany, and Spain, the validation study of the B-ADL was carried out in three stages. The aim of our research is to verify the validity and reliability of the Turkish version of B-ADL.
