Harvard Group Scale With African AmericanCollege Students


Marty Sapp, Ed.D.and Kim Hitchcock, Ed.D.




The purpose of this study was to assess hypnosis,with African American college students,
using the Harvard Group Scale of Hypnotic Susceptibility,Form A (HGSHS:A).Two hundred
seventeen undergraduate African American students participated in this study.Students
completed the HGSHS:A,a measure of hypnotic depth,the Dissociative Experiences Scale
(DES),the Inner Subjective Experiences scoring of the HGSHS:A,a measure of nonvoli-
tional responding,and the Tellegen Absorption Scale (TAS).This sample was compared to
other samples on the HGSHS:A.A one-way ANOVA did not find that the African
American college sample differed from two European American college samples in terms
of difficulty indices on items on the HGSHS:A;however,the reliability of the HGSHS:A for
the African American college sample was lower than the other two American college
samples,and these researchers suggest that the Inner Subjective Experiences method for
scoring the HGSHS:A may be more appropriate for African American college students than
the behaviorally scored items of the HGSHS:A.(Sleep and Hypnosis 2001;3(3):120-126)
