 Aims and background: Aim and Background: The Centrality of Pain Scale as a brief scale was developed to assess how pain is central, or dominant in the lives of individuals with chronic pain disorders. The aim of this study was to validate the reliability of the measurements of this scale among Iranian patient with chronic pain disorders. Materials and methods: The current study was conducted in a correlation research context. A group of 150 patients with chronic pain disorders took part in this research. Participants answered the Centrality of Pain Scale )COPS(, the McGill pain questionnaire and the Toronto Alexithymia Scale. Data were analyzed using explanatory factor analysis, multiple analyses of variance and Pierson correlation coefficient. Findings: Two factor solutions were extracted using Principal Component Analysis that named pain dominance and pain control. The convergent validity was found to be high. According to the results, females had higher scores on total scale and pain dominance factor than males. The internal constancy and test retest reliabilities were found to be acceptable. Conclusions: Based on these results, it was concluded that Centrality of Pain Scale contain good validity and reliability in an Iranian population with chronic pain disorders.
