Pain and Tool Development

Pain is defined as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage” (International Association for the Study of Pain (IASP), 1986).

It provides a continuous scale and so is preferred over discontinuous methods such as numerical and verbal rating scales (Carlsson, 1983).

Validity can be defined as ‘truthfulness: does the test measure what it intends to measure?’ (Mehrens et al, 1987). When measurements are made they must be representative, suitable for purpose and applicable to the setting in which they are used (Brooker et al, 2007). The intention of the VAS is to assess the intensity or severity of a patient’s pain. It is based on the assumption that the scale is completed by the patient, as scores taken from staff and/or family have been proven to be inaccurate (Stannard, 2004). “Pain is what the patient says it is” (McCaffery, 1983), ‘The foundation of pain assessment is the patient’s self report’ (Jacox et al, 1994).
