The British use of the Barber Suggestibility Scale: norms, psychometric properties and the effects of the sex of the subject and of the experimenter.

The Barber Suggestibility Scale, as a measure of hypnotic susceptibility, was administered to 130 British undergraduate students by 13 student experimenters in a 2 x 2 factorial design withe sex of the subject and the sex of the experimenter as the two variables. The results showed no significant differences among the scores obtained by the 13 experimenters and no significant effect of either the subject's sex or the experimenter's sex though there was some tendency towards an interaction effect. The distribution of scores from the present sample was similar to the American norms reported by Barber (1965) except for slightly lower means on certain test-suggestions. The scale also showed satisfactory internal consistency and item-scale correlations. A principal components analysis revealed evidence for a general factor underlying the scale in addition to three special factors associated with direct motor, motor challenge and cognitive suggestions which confirms the work of Hilgard (1965) on the Stanford scales. The distinction between objective and subjective responses to suggestions is discussed and some improvements are recommended in the scale. It was concluded that the BSS appears to be a simple and reliable measure of hypnotic susceptibility and is suitable for British usage.

An investigation of the role of 'hypnosis', hypnotic susceptibility and hypnotic induction in the production of age regression.

In response to criticisms of the methodology of Barber's(1969)experiments, a 2x2 factorial design, varying hypnotic susceptibility and hypnotic treatment, was used to study the role of 'hypnosis' in the production of age regression by suggestion. Twenty subjects of high hypnotic susceptibility and 20 subjects of low hypnotic susceptibility were randomly allocated to one of two treatment conditions:hypnotic induction procedure or motivational instructions. Both treatments were followed by suggestions to regress to the age of seven years. Two measures of age regression were taken:the Draw-A-Man-Test and a subjective rating of the reality of the experience. The results showed significant effects of both variables, with high suceptibility and induction treatment producing better regression on both measures than low susceptibility and motivation treatment. Hypnotic susceptibility was the stronger of the two variables. The ranking of the four conditions corresponded with predictions of hypnotic depth from the state theory of hypnosis, but the findings were not inconsistent with the non-state theory. The drawings of all regressed groups were more mature than the norms for the age of seven and the drawings of a group of seven year old children.
