Pain Assessment Tool for Postoperative Pain


The VAS can be used reliably in an emergency setting for acute pain experience. Intra-class correlation coefficient with 95% confidence intervals was calculated (0.97, 95% confidence intervals 0.96-0.98) for the measurement of acute pain in adults of respondents was 1 minute every 30 minutes to 2 hours. The study concluded that 90% of a rating may be reproduced in the 9-mm, indicating a high level of reliability when used in the assessment of acute pain.


As noted above, McCaffery (1989) argues that "any pain the patient says it exists when they are told what to do. Thus, one aspect of the reliability of the VAS should be the extent to which it may provide patients a sense of pain. In a recent study, Freeman et al. (2001), a high correlation (r = 0.92)

was established between the VAS and the results of non-verbal expressions using Faces rating scale.

In fact, the VAS to measure pain were created using various methods, including the creation of parallel construction, and criteria related validity (Seymour 1982, Price et al. 1983, Gift 1989). The second of these studies, the VAS has been confirmed as a ratio scale of measurement in chronic pain and experimental, and the simultaneous action was established in the latter study. Downie et al. (1978) compared the validity of VAS and its simplicity and ease of use, with the same VDS and the NRS. It was found that all scales are well correlated and the same load on a factor analysis. Seven years later, Littman et al. (1985) compared with the VDS VAS and verbal scale of pain in patients with acute and chronic pain (N = 1497). It was...
