Objectives

People with bipolar disorder are two to three times more likely to smoke and 50% less likely to quit than the general population. New treatments are needed to improve smoking cessation outcomes in this group. The study aim was to develop and pilot test a novel cessation intervention for smokers with bipolar disorder using Acceptance and Commitment Therapy (ACT) combined with nicotine patches.

Methods

The ten-session ACT intervention was initially evaluated as in-person, individual counseling (n = 10), then as telephone-delivered counseling (n = 6). Participants were adult smokers with no more than mild current symptoms of bipolar disorder.

Results

For the in-person protocol, end-of-treatment outcomes were: 80% retention, 40% of participants with carbon monoxide (CO)-verified seven-day point prevalence abstinence (PPA), 90% satisfied with treatment, 8.3 of ten sessions attended, and 54% increase in acceptance of cravings to smoke (i.e., ACT's theory-based change process) from baseline. The seven-day PPA at one-month follow-up was 30%. For the telephone protocol, end-of-treatment outcomes were: 67% retention, 33% reporting seven-day PPA, 100% satisfied with treatment, 6.7 of ten treatment calls completed, and 55% increase in acceptance from baseline. At one-month follow-up, seven-day PPA was 17%. The proportion of treatment completers who used at least 80% of the nicotine patches was 62.5% for the in-person protocol and 0% for the telephone protocol.

Conclusions

Both in-person and telephone-delivered ACT were feasible. Despite low adherence to nicotine patches, the intervention showed preliminary evidence of facilitating quitting and impacting ACT's change mechanism. A randomized, controlled trial of this targeted ACT intervention is now needed.
