Detailed Description

Two investigators will do the translation into Greek, then a third person independent of the first two will translate the scale backward, i.e. into English. Then, the three investigators will meet with another independent investigator who is familiar with the field of Greek translations of foreign language rating scales. Thus, the final translation and Greek version of the scale will be created. Then, the process of finding the participants will begin and the first assessment with the scale will be carried out initially. After two days will take place reassessment for the reliability of the measurement tool. In order to find the validity of the scale in the Greek population, in the first assessment will be used also Katz index for Basic Activities of Daily Living and the Lawton scale for Instrumental Activities of Daily Living.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Disability Assessment for Dementia and change from baseline
Time Frame: At baseline and after two days for checking the change and therefore the reliability. The score can range between 0 - 40, where 40 means complete independence in activities of daily living.
The scale is completed by the patient's caregiver with the assistance of the assessor-therapist.
At baseline and after two days for checking the change and therefore the reliability. The score can range between 0 - 40, where 40 means complete independence in activities of daily living.
