Method: Data were collected from a convenience sample of 311 patients with chronic pain. The psychometric properties of the Catastrophizing Thoughts sub-scale were assessed by analyzing the reliability and validity of this tool. Results: The Catastrophizing Thoughts Scale mean score for this population was 2.38 (SD = 1.8). Cronbach alpha coefficient was 0.89, and the split-half correlation (Pearson) was 0.74, indicating adequate internal consistency and correlation between halves. The main component analysis indicated the existence of 2 components (hopelessness and rumination). Discriminant and criterion validity were also adequate. Significant correlations were found between the Catastrophizing scale and disability, pain intensity and pain site. among the studied variables, catastrophizing was the strongest predictor of disability, even higher than pain intensity. Conclusion: altogether, these results showed that the Catastrophizing sub-scale has good psychometric properties when used in a Brazilian chronic pain patient sample and the contribution of catastrophizing to physical disability. The results of this study were consistent with those previously published in the literature.
