Title

A Study on the Psychometric Properties of Revised‑nonverbal Pain Scale and Original‑nonverbal Pain Scale in Iranian onverbal‑ventilated Patients

English Abstract

The nonverbal pain scale is one of the instruments which study pain in nonverbal‑ventilated patients with regard to the changes of behavioral and physiological indices. The purpose of the study is to survey the psychometric properties of revised‑nonverbal pain scale (R‑NVPS) and original‑nonverbal pain scale (O‑NVPS) in ventilated patients hospitalized in critical care units. Four nurses studied pain in sixty patients hospitalized in trauma, medical, neurology, and surgical critical care units using R‑NVPS and O‑NVPS at six times (before, during, and after nociceptive and nonnociceptive procedures). The test was repeated in 37 patients after 8–12 h. Cronbach’s alpha coefficient for R‑NVPS and O‑NVPS was 0.8 and 0.76, respectively. The inter‑rater correlation coefficient during different times was r = 0.89–0.96 for R‑NVPS and r = 0.80–0.87 for O‑NVPS. Test‑retest correlation coefficient for R‑NVPS and O‑NVPS was r = 0.55–0.86 and r = 0.51–0.75, respectively. The meaningful difference in pain score between nociceptive and nonnociceptive procedures (P < 0.001) and a higher pain score in patients who confirmed pain (P < 0.001) showed a discriminant and criterion validity for both scales of NVPS, respectively. R‑NVPS and O‑NVPS can both be used as valid and reliable scales in studying pain in ventilated patient. However, in comparing the items, “respiration” (R‑NVPS) had a higher sensitivity than “physiology II” (O‑NVPS) in assessing pain.
