Rating Scales

About 'Recommended' Scales

According to the current definition (which has slightly evolved over time), a scale is considered "recommended" if it has been applied to PD populations, there are data on its use in studies beyond the group that developed the scale, and it has been studied clinimetrically* and found valid, reliable and sensitive to change.

*The latter requirement refers to clinimetric testing in any population of patients, but scales tested in PD populations with good clinimetric profiles are favored over those successfully tested in other populations, but not PD. Among Recommended scales, this prioritization is discussed in the body of the report and conclusions.
