Revision of Design of financial incentive programmes: A discrete choice experiment

Financial incentive programmes promote smoking cessation. However, the incentive amount which should be provided – and how this may interact with other programme characteristics – is unknown. The objective of this study was to evaluate the influence of the design of incentive programmes for smoking cessation on current smokers’ perceptions of programmes and willingness to enrol. An online discrete choice experiment was conducted amongst adult current smokers residing in the United Kingdom (N = 430). Hypothetical incentive programmes were described using five attributes (incentive amount, incentive type, frequency of sessions, reward schedule, programme location). Participants responded to a series of choice sets comprised of two hypothetical programmes. For each set, participants selected their preferred programme. They then specified whether they would enrol in their preferred programme if it were available. Analyses also considered the effect of participant income on preferences.
