Validity, reliability, and responsiveness of a digital version of the visual analog scale.
UNLABELLED The design used in this study was a prospect i ve cohort . Pain intensity levels recorded by the digital version of the visual analog scale ( VAS-D ) are easy to both score and share with other health care professionals . The purpose of the study was to examine the test-retest reliability , concurrent validity , and responsiveness of the VAS-D.  Thirty-three people with upper extremity injuries reported pain intensity levels before and after performing four maximal grip contractions ( pre- and postgripping ) . Our version of the VAS-D had high test-retest reliability ( r=0.96 ) and good concurrent validity ( r=0.84 - 0.97 ) with both the paper version of the VAS ( VAS-P ) and the verbal numerical rating scale ( NRS-V ) . Responsiveness of the VAS-D was indicated by a significant increase in pain levels from pre- to postgripping . Similar responsiveness to that of the VAS-P and NRS-V was indicated by similar effect size coefficients and analysis of variance of pain change scores . In conclusion , the VAS-D is a reliable , valid , and responsive measure of pain intensity for people with upper extremity injuries . However , differences in accuracy ( resolution ) among the VAS-D , VAS-P , or NRS-V may render the three pain scales not fully compatible . LEVEL OF EVIDENCE Not applicable
