Primary outcome measure(s)
Validity of the Turkish Version of the Parkinson's Disease Cognitive Functional Rating Scale — Baseline Parkinson's Disease Cognitive Functional Rating Scale assesses the functional impact of cognitive impairment in individuals with Parkinson's disease. The 12-item scale assesses cognitive impairment while minimizing motor effects. Items are scored 0-2. Unperformed tasks (score 8) are replaced by the average of scored items and summed. The total score ranges from 0 to 24. Higher scores indicate worse outcomes.
The validity of the Turkish version of the scale will be evaluated through convergent and discriminant construct analyses. Convergent validity will be assessed by examining partial Pearson correlations between Parkinson's Disease Cognitive Functional Rating Scale scores and Mini-Mental State Examination and Montreal Cognitive Assessment scores.
Discriminant validity will be analyzed using binary logistic regression with Mini-Mental State Examination and Montreal Cognitive Assessment scores and disease duration as independent variables.
