Scoring

The score is the number circled or histogram marked (radio buttons below the numbers are used on the Internet version). Scores range from 0 to 10, with the higher score indicating more shortness-of-breath. If two consecutive numbers are circled, score the higher (more SOB) number, if two non-consecutive numbers are circled, do not score.

Comments

This scale is a modified version of the visual analog scale. We found that this scale is easier for subjects to use, resulting in less missing and unclear responses. The scale above is that used for our Internet studies, with color and shading used. The psychometrics were done on a print black-and-white version, which is printed in the PDF version of this page (see link on the bottom of this page). The VNS was originally developed in Spanish.
