The SCales for Outcomes in PArkinson's disease-COGnition (SCOPA-COG) is a short, reliable and valid instrument for assessing cognitive function in PD. The SCOPA-COG consists of 10 items divided over four domains: memory (4 items); attention (2 items); executive function (3 items) and visuospatial function (1 item). Scores range from 0-43, with higher scores reflecting better performance.

The development of the SCOPA-COG is part of a larger research project, the SCales for Outcomes in PArkinson’s disease (SCOPA), in which practical and clinimetric sound instruments for all relevant regions in PD are selected or developed. The SCOPA instruments were originally developed in the Dutch language.

Inclusive Language in Clinical Outcome Assessments

Healthcare providers should tailor the language used in COAs to reflect each patient’s gender identity. In grammatically gendered languages, the practice includes making appropriate linguistic adjustments to ensure communication is respectful and inclusive throughout the assessment process.
