Brief Summary

Tobacco use is the greatest cause of ill health and early mortality, and smoking is the main contributor to around 75,000 deaths a year in England. The aim of the present research is to test the effect of helping people to reward themselves when they have successfully abstained from smoking and the impact this will have on subsequent smoking cessation. Each participant will be randomly allocated to one of four conditions. The trial requires 159 participants to perform an fully powered statistical analysis. The four conditions include: (1) a control condition (asked to form a plan to quit smoking), (2) an implementation intention condition (asked to form a more specific 'if-then' plan), (3) baseline which include: (1) a control condition (asked to form a plan to quit smoking), (2) a volitional help sheet condition (asked to link temptations with appropriate behavioural responses), (3) a weekly self-incentivising condition (asked to reward themselves at the end of each week that they have successfully abstained from smoking), or (4) a monthly self-incentivising condition (asked to reward themselves at the end of each month that they have successfully abstained from smoking). The main outcome measure will be smoking quit status, which will be verified biochemically at the end of the stop smoking programme, and at six-months post quit date.

Study Arms (4)

Control

ACTIVE COMPARATOR

Participants read a brief statement designed to encourage them to quit smoking (we would like you to plan to quit smoking). Participants are then asked to form their plan to quit smoking.

Behavioral: Self-Incentive

Implementation Intention

ACTIVE COMPARATOR

Participants read a brief statement designed to encourage them to quit smoking (we would like you to plan to quit smoking). Participants are then asked to form a specific 'if-then' plan using an implementation intention basis.

Behavioral: Self-Incentive

Weekly Self-Incentivising

EXPERIMENTAL

Participants read a brief statement designed to encourage them to quit smoking (we would like you to plan to quit smoking). Participants are then asked to specify a self-incentive on which they could implement at the end of each week which they have been successful in not smoking.

Behavioral: Self-Incentive

Monthly Self-Incentivising

EXPERIMENTAL

Participants read a brief statement designed to encourage them to quit smoking (we would like you to plan to quit smoking). Participants are then asked to specify a self-incentive on which they could implement at the end of each month which they have been successful in not smoking.

Behavioral: Self-Incentive

Interventions

Self-Incentive BEHAVIORAL

Participants are asked to form plans to quit smoking using various descriptions specified dependent on the arm in which they are randomised.

Control; Implementation Intention; Monthly Self-Incentivising; Weekly Self-Incentivising
