Hypnotic depth, hypnotic susceptibility, and the relationship between the two were studied in two separate samples. In the first study, 45 aubjects were tested on the Creative Imagination Scale (CIS) and the induction part (i.e. the eye closure item) of the Stanford Hypnotic Susceptibility Scale, Form A (SHSS:A). Retrospective depth reports were taken, and hypnotic responsiveness scores on the CIS was assessed. The results demonstrated significantly higher depth scores for the SHSS:A (eye closure) than for the CIS. Moreover, there was a significant correlation between hypnotic susceptibility and depth score on the CIS. In the second study, 19 subjects were again tested on the CIS and the eye closure item of the SHSS:A. As in the first study, spontaneous depth estimates were elicited. In addition, the subjects were required to estimate their experiences retrospectively according to three distinct operationalizations of hypnotic depth, i.e. depth in terms of bodily relaxation, absorption, and dissociation. Analysis of variance revealed a highly significant effect for depth measures, and a significant depth measure by hypnosis method interaction effect. Hypnotic depth defined as bodily relaxation produced the highest score, followed by absorption. The mean scores were lowest for spontaneous depth and dissociation. Again, significant correlations between susceptibility and depth reports were found.
