This study compared the relative efficacy of two different theoretically-derived strategies in the hypnotic treatment for cigarette smoking. The use of counterconditioning suggestions (present or absent) was compared to the use of role-playing suggestions (present or absent) in a two-way factorial design. Also investigated was whether there were any pretreatment variables which could predict successful long-term smoking control. Fifty adult chronic smokers were matched on the dimensions of baseline smoking rate, number of years smoking and number of previous attempts to quit smoking, then assigned to one of four treatment groups. All subjects were offered four sixty-minute group hypnotherapy treatment sessions over a three week period, with smoking rate assessed at the second, third and fourth sessions, and at one-month, three-months and six-months post-treatment. The two dependent measures of percentage reduction from baseline smoking rate and percentage of subjects in each treatment group remaining abstinent from smoking showed similar results. ANOVA procedures found a significant Time of assessment X Counterconditioning interaction, indicating that the use of counterconditioning suggestions facilitates the long-term maintanence of smoking control more than the use of role-playing suggestions or a "hypnotic relaxation" treatment using no specific suggestions. The demographic variables of increased age, having a smoking-related health problem, and being a "stimulation" type of smoker were found to correlate highly with successful long- term outcome and to correctly classify subjects as abstainers or nonabstainers the majority of the time.
