The effect of two procedures on hypnotic susceptibility modification

The object of this research was to compare the effectiveness of two standardized programmes of hypnotic susceptibility modification, that of Sachs and Anderson (1967) and the Carleton Skills Training Package (CSTP) (Gorassini and Spanos, 1986). The results showed a statistically significant difference between these two programmes and the control group for both objective and subjective reponses to the suggestions, but no significant difference between the two programmes. The effectiveness of the CSTP in modifying hypnotic responsiveness scores, which had been placed in doubt in several studies, was confirmed.
