Eighty-five smokers chose either a group or individual treatment using manualized hypnosis. Abstinence rates in group treatment at follow-up are 19.6% in comparison to 13.8% in individual treatment. This difference did not reach statistical significance. It is concluded that group treatment is as effective as the better established individual treatment and therefore can be seen as an alternative approach in smoking cessation using hypnosis.
