Study of the Test-retest Reliability of the Neuropsychiatric Fluctuations Scale (EFN)
Source: ClinicalTrials.gov · Last updated 30 Sept 2026
Brief summary (registry, in English)
This study focuses on neuropsychiatric fluctuations (NPF) in Parkinson's disease. Due to the lack of specific assessment tools, we developed the Neuropsychological Fluctuations Scale (NFS), a 20-item questionnaire. Recent studies have confirmed its reliability, sensitivity, and validity. To finalize its validation, assessing its test-retest reliability is an essential next step.
