Abstract

The aim was to analyse the existing relation between a subjective evaluation of pain with the use of the Verbal Numerical Scale (VNS) and an objective behavioural measure associated with pain, by means of the Pain Behaviour Rating Scale (UAB). An observational correlation study was carried out in a hospital environment. The study included 61 patients affected with multiple forms of non-malignant chronic pain; the behaviour was observed by the nursing staff. In general, a positive but moderate correlation was obtained between VNS and UAB scales (r=0.29, p<0.0001). Observing behaviour and listening to the patient constituted two complementary and non-interchangeable methods for assessing the level of pain capable of providing a global and objective portrayal of the pain experience.
