简要总结
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.
详细描述
The research aims to test the role of self-incentivising implementation intentions in smoking cessation among prisoners aged 18 and over, enrolling on a stop smoking programme provided by Livewire within Risley Prison. The effectiveness of self-incentives has been successfully seen previously within health behaviour change, but not within smoking cessation (ongoing randomised controlled trial in alongside community stop smoking services, and local workplaces). This research will build on this by testing the effectiveness of self-incentives in prisoners' stop smoking attempts.
This study is a randomised controlled trial with the between participants factor of condition which has four levels:
- Control (plan) 2 Self-generated implementation intention (if-then plan) 3. Weekly self-incentivising implementation intention 4. Monthly self-incentivising implementation intention
The within participants' factor will be time which has three levels:
- Baseline (T1)
- Follow-up (T2) (end of stop smoking programme)
- Follow-up (T3) (six months post quit date)
