简要总结
Continuous levels of hazardous alcohol consumption (i.e., 14 or more units per week) is one of the leading risk factors of ill health and early mortality, contributing to around 9,809 deaths a year in the UK. The aim of the present research is to test the effect of helping people to reward themselves when they have successfully reduced/abstained from their previous levels of alcohol consumption. Each participant will be randomly allocated to one of two conditions. The trial requires 128 participants to perform a fully powered statistical analysis. The two conditions include: (1) a control condition (asked to form a plan to reduce/abstain from alcohol consumption), or (2) a weekly self-incentivising condition (asked to reward themselves at the end of each week that they have successfully reduced/abstained their previous levels of alcohol consumption). The main outcome measure will be units of alcohol consumed/not consumed, which will be self-reported at 1-week and 1-month follow-up time points.
详细描述
The research aims to test the role of self-incentivising implementation intentions for reductions/abstinence of alcohol consumption among people aged 18 and over, residing in the UK, and consuming 14 units of more of alcohol at the start of the study. The effectiveness of self-incentives has been successfully seen previously within health behaviour change, has not been tested in reduction/abstinence of alcohol consumption. Therefore, this research will build on what is known about the effectiveness of self-incentives used for increasing fruit and vegetable consumption, and smoking cessation.
This study is a randomised controlled trial with the between participants factor of condition which has two levels:
1. Control (plan) or 2. Weekly self-incentivising implementation intention.
The within participants' factor will be time which has three levels:
Baseline (T1) Follow-up (T2) (1-week following baseline) Follow-up (T3) (1-month following baseline)
