Sex differences in prior pain experience.

Unlabelled: Sex differences in clinical and experimental pain experiences are well documented. However, there has been little work investigating men's and women's experiences with common painful events. This study examined sex differences in the nature and intensity of common pain experiences. Participants (102 women and 85 men) completed the Prior Pain Experience Questionnaire, which is a 79-item assessment of an individual's pain experience, recalled pain ratings, and imagined pain ratings. Analyses of variance were conducted to assess for sex differences in overall pain experience and pain ratings. Men and women did not have significant differences in the overall number of reported pain experiences or in the overall mean pain rating of those experiences. However, they differed in specific pain events experienced (eg, men experienced concussions more than women) and pain ratings (eg, women rated minor surgery as significantly more painful than men). Individuals who imagined pain events tended to rate them as equally or more painful than individuals who experienced those pain events.

Perspective: Results of this study demonstrate that men and women have varying types of pain experiences without evidence that the overall pain experience differs between sexes. It was also found that imagined pain ratings are often worse than experienced pain ratings, lending support for the tendency of individuals to catastrophize.
