Abstract

The Scales for Outcomes in Parkinson's disease- Cognition (SCOPA-Cog) has been shown to be a clinimetrically rigorous and valid instrument for a disease- oriented neuropsychological assessment of Parkinson's disease (PD) patients. In the present study we evaluated the psychometric properties of the Italian version of the SCOPA-Cog in 121 PD patients. The scale explores memory, attention, and executive and visuospatial functions and takes approximately 20 minutes to administer. Data distribution (skewness= -0.23) and internal consistency (Cronbach's alpha= 0.78) wre sateisfactory. Standard error of measurement was 3.42. The outcome was significantly worse in patients with an abnormal score on the Dementia Rating Scale (DRS) (SCOPACog mean score 14.6±5.1 out of a total of 43) with respect to cognitively intact subjects (24.2±4.3) (p
