M., Stout, M., Abplanalp, S., & Hirsh, A. T. (2017). Pain-Related Rumination, But Not Magnification or Helplessness, Mediates Race and Sex Differences in Experimental Pain. The Journal of Pain, 18(3), 332-339. https://doi.org/10.1016/j.jpain.2016.11.005 Abstract Compared to White individuals and men, Black individuals and women demonstrate a lower tolerance for experimental pain stimuli. Previous studies suggest that pain catastrophizing is important in this context, but little is known about which components of catastrophizing contribute to these race and sex differences. The purpose of the current study was to examine the individual components of catastrophizing (rumination, magnification, and helplessness) as candidate mediators of race and sex differences in experimental pain tolerance.
