About

The aim of the present study is to translate the Parkinson's Disease-Cognitive Functional Rating Scale into Turkish (PD-CFRS-Turkish version) and to evaluate its validity and reliability.

Full description

The Parkinson's Disease-Cognitive Functional Rating Scale (PD-CFRS) is one of the Parkinson's disease-specific instruments developed to assess a broad range of functional impairments resulting from cognitive deficits in individuals with Parkinson's disease (PD). The PD-CFRS is specifically designed to evaluate cognitive dysfunction while minimizing the confounding effects of motor symptoms.

The scale consists of 12 items that assess whether the patient experiences difficulties in performing activities such as managing money and household finances, arranging vacations or meetings, handling personal correspondence, checking medication schedules, organizing daily routines, using electrical appliances, understanding public transportation, dealing with unforeseen situations, expressing intentions, comprehending written information, and using a mobile phone.

Each item is rated on a 3-point scale ranging from 0 to 2. If the participant has never performed the activity in question, a score of 8 is assigned. At the end of the assessment, the average score for items rated between 0 and 2 is calculated and rounded to the nearest whole number. This value replaces all items initially scored as 8. Once all substituted scores are assigned, the total score is obtained by summing all item scores. The administration time for the scale is approximately 5 minutes.
