Hypnosis and behavioral treatment in a worksite smoking cessation program.

In the initial study, 48 subjects of the total (N = 63) ultimately used, were assigned to one of three treatments: four hypnotic sessions with a booster, two hypnotic sessions, or two hypnotic and two behavioral sessions with a booster. A follow-up group was later recruited composed of 15 subjects who received four hypnotic sessions and a booster session with less time between sessions. The results indicated no difference in smoking cessation 6 months after treatment regardless of the frequency, length between sessions, or addition of behavioral methods. Successful subjects were more educated, less able to utilize their imagination, and had fewer smokers at home.
