The Critical Path Institute (C-Path) eCOA consortium has written a new article "Implementing Numeric Rating and Visual Analog Scales in an eCOA Solution" published in Applied Clinical Trials Magazine.
The article explains the challenges and best practice recommendations for the digitalization or electronic implementation of the numeric rating scale (NRS) and visual analog scale (VAS), from the original Clinical Outcome Assessments (COAs) into electronic versions, also called eCOA.
Proper digitalization of the numeric rating and visual analog scale is indeed critical to ensure integrity and consistency of a measure’s psychometric properties and trial outcomes.
