On the basis of the transtheoretical model of change, we hypothesized that hypnosis would facilitate significantly greater movement through the stages of change toward smoking cessation in contrast to psychoeducation. Thirty participants were pretested for hypnotizability using the Elkins Hypnotizability Scale (EHS). Participants’ readiness for change was assessed using the University of Rhode Island Change Assessment scale (URICA). The EHS relaxation induction was used to induce hypnosis. Hypnotic suggestions addressed motivation and ambivalence. The URICA was administered following the intervention and at a 10-day follow-up. Two-factor split-plot ANOVAs showed significant changes within groups on the contemplation subscale (p = .002), action subscale (p = .00007), and the number of cigarettes smoked per day (p = .003).
Despite the apparently definitive findings of the Christensen (2005) survey of published members of the Society for Clinical and Experimental Hypnosis (SCEH), disagreement about which term best describes the capacity to experience hypnosis and theoretical preference has continued. SCEH, although international, represents primarily North Americans. Preferences of international clinicians and researchers were inadequately represented, so the authors surveyed preferences from attendees of the International Congress of the International Society of Hypnosis in 2012 in Bremen, Germany. The term trance, translated as trance capacity or trance ability for this study, was overwhelmingly preferred over the other options. Hypnosis was recognized as an identifiable state by 88.46% of respondents, whereas only 11.54% viewed it as a sociocognitive phenomenon (role-play, expectancy, etc.).
