THE COMPUTER-ASSISTED HYPNOSIS SCALE - STANDARDIZATION AND NORMING OFA COMPUTER-ADMINISTERED MEASURE OF HYPNOTIC ABILITY

In a counterbalanced, within-subjects, repeated measures design, 130 p articipants were administered both the Computer-Assisted Hypnosis Scal e (CAHS; C. D. Grant, 1993) and the Stanford Hypnotic Susceptibility S cale, Form C (SHSS:C; A. M. Weitzenhoffer & E. R. Hilgard, 1962). For each hypnotic procedure, responsiveness was assessed along three dimen sions: behavioral (CAHS, SHSS:C), subjective depth (Field Depth Invent ory; P. B. Field, 1965), and relational involvement (Archaic Involveme nt Measure; M. R. Nash & D. Spinler, 1989). The CAHS was shown to be a psychometrically sound instrument for measuring hypnotic ability. The various dimensions of CAHS hypnotic responsiveness were highly positi vely related, and the CAHS compared favorably with the SHSS:C across t he three dimensions assessed. Results are discussed in terms of the th eory and practice of clinical assessment, noting directions for future research.
