The Alcohol Toolkit Study (ATS) is a monthly household survey of representative samples of the adult population in England that aims to provide insight into population-wide influences on alcohol consumption and related behaviour. Since 2014, the survey has collected data from over 50,000 people on alcohol consumption and related harm (AUDIT), beverage type and expenditure, exposure to brief intervention, attempts and motivation to reduce consumption, and use of aids and motives for cutting down. The ATS is the sister survey to the Smoking Toolkit Study, which means the same respondents also provide data on a range of sociodemographic and smoking characteristics. The project is a collaborative effort between six centres across England and the data have been used for a variety of purposes. This talk will introduce the survey and briefly highlight findings from three separate studies that aimed i) to compare the prevalence and characteristics of people who smoke or drink excessively and who receive a brief intervention, ii) to assess whether smokers who recently attempted to quit are more likely than other smokers to report lower alcohol consumption or a recent attempt to cut down, and iii) to evaluate the short-term effect of announcing revised lower risk drinking guidelines on related awareness and knowledge.
