Sex differences on the HGSHS:A

American Journal of Clinical Hypnosis, Jul 2004 by Hammond, D Corydon

Rudski, J. M., Marra, L. C., & Graham, K. R. (2004). Sex differences on the HGSHS:A. International Journal of Clinical & Experimental Hypnosis, 52(1), 39-46. A huge sample of 724 men and 1148 women were given the Harvard Group Scale of Hypnotic Susceptibility over a 28 year period. Women were found to have scored higher than men, and this effect was found to be most prominent on 6 of the 12 items, many of them challenge items (identified by principal-components analysis).

The overall effect size, however, was small. The results are discussed in terms of differences in item difficulty. Address for reprints: Jeffrey M. Rudski, Dept. of Psychology, 2400 Chew St., Muhlenberg College, Allentown, PA 18104, USA. E-mail: rudski@muhlenberg.edu.
