ObjectiveThe Defense and Veterans Pain Rating Scale (DVPRS 2.0) is a pain assessment tool that utilizes a numerical rating scale enhanced by functional word descriptors, color coding, and pictorial facial expressions matched to pain levels. Four supplemental questions measure how much pain interferes with usual activity and sleep, and affects mood and contributes to stress.MethodsPsychometric testing was performed on a revised DVPRS 2.0 using data from 307 active duty service members and Veterans experiencing acute or chronic pain. A new set of facial representations designating pain levels was tested.ResultsResults demonstrated acceptable internal consistency reliability (Cronbach's alpha = 0.871) and test-retest reliability (r = 0.637 to r = 0.774) for the five items. Excellent interrater agreement was established for correctly ordering faces depicting pain levels and aligning them on the pain intensity scale (Kendall's coefficient of concordance, W = 0.95 and 0.959, respectively). Construct validity was supported by an exploratory principal component factor analysis and known groups validity testing. Most participants, 70.9%, felt that the DVPRS was superior to other pain rating scales.ConsclusionThe DVPRS 2.0 is a reliable and valid instrument that provides standard language and metrics to communicate pain and related outcomes.Published by Oxford University Press on behalf of the American Academy of Pain Medicine. 2016.
