Research on the efficacy of hypnosis has been limited due to the lack of a sham hypnosis comparison in randomized clinical trials. Researchers have relied on a variety of controls ranging from wait-lists to structured attention, resulting in a lack of blinding of participants and inconsistency among findings. The present study was designed to evaluate (a) whether white noise can be considered an 'inert' procedure and (b) the feasibility of a model of sham hypnosis that uses white noise presented within the hypnotic context. Seventy-five participants were randomized to one of three groups: hypnosis, sham (white noise presented in the context of hypnosis), or control (white noise in the absence of hypnotic context). Measures included participants' ratings of: (1) therapist professionalism; (2) consistency of the environment with hypnosis; (3) participants' perception that they received hypnosis; (4) the procedure as pleas- ant, relaxing, and beneficial; (5) the acceptability of the procedure; and (6) shifts in relaxation and expected benefit of hypnosis resulting from each procedure. No significant differences were observed among groups in ratings of professionalism. However, significant differences emerged with respect to the other measures when comparing participants who received sham hypnosis and those who received a hypnotic induction versus participants assigned to the white noise control, with effect sizes ranging from 0.17 to 0.85. Also, consistent with expectations, there were no significant differences between ratings of the sham hypnosis and the hypnosis procedure with respect to any of the remaining measures. Results support the feasibility of using white noise as an inert procedure that can serve as a credible sham hypnosis. [ABSTRACT FROM AUTHOR] |
