 This study evaluated the structural validity of a 16-item subscale of a gender, pain, and expectation scale, GPS, to explore traditionally genderized traits on pain, finding a three-factor structure informed by 10 items, a motive, relationship-oriented, and goal-oriented. Evidence of construct validity was supported through significant sex-based differences in the expected directions for all three subscales. The researchers recommend focusing on the nature of the traits rather than naming them masculine or feminine. Implications for researchers conducting sex-based gender-based pain research are discussed. This article was authored by Maryam Gadradi, David M. Walton and Joy C. McDermid.
