Effectiveness and feasibility of the self-administered and repeated episodic future thinking exercises in smoking cessation

Delay discounting (DD) is associated with smoking behavior and relapses. Episodic future thinking (EFT) is one of the leading interventions shown to reduce DD. The 1-month follow-up study with 60 participants that employed EFT as active intervention and episodic recent thinking (ERT) as control intervention was conducted in participants receiving smoking cessation treatment. In EFT group, there was significant decrease in DD rates from pre-intervention to post-intervention ( = 0.009), whereas no significant change was observed in ERT group ( = 0.497). DD rates in EFT group did not change significantly over 1 month ( = 0.059), while decrease was detected in ERT group ( = 0.011). Smoking cessation rates between groups were similar ( = 0.486). Adherence with completing follow-up evaluation forms and performing relevant exercises was higher in EFT group ( = 0.038, = 0.006). Adding EFT to usual smoking cessation treatment did not increase smoking cessation rates, however feasibility of the self-administered exercises needs to be improved to clarify clinical effects.
