5 Despite their substantial strengths, the VRSs also exhibit a number of weaknesses, based on which other pain researchers have hesitated to recommend these scales. First, the scoring method for a VRS assumes equal intervals between adjectives. ” This assumption is rarely tested, and is likely often violated. This property of the VRS poses difficulties in both the interpretation and analysis of VRS-derived data. Second, in order to use VRS properly a patient must both be familiar with all of the words used on the scale and must be able to find one that accurately describes his or her pain.
