Scales for Outcomes in Parkinson’s Disease – Psychosocial Functioning (SCOPA-PS)


Acronym: SCOPA-PS

Authors: Marinus J, Visser M, Martínez-Martín P, van Hilten JJ, Stiggelbout AM


The SCales for Outcomes in PArkinson’s disease- Psychosocial Functioning (SCOPA-PS) is a self-administered, 11-item questionnaire assessing psychosocial functioning during the preceding month, on a scale ranging from 0 (not at all) to 3 (very much). A summary index is calculated by transformation of the items sum score into a percentage of the maximum possible score (33 points). The higher the summary index, the worse the psychosocial functioning.

The development of the SCOPA-PS 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.
