Practical demonstration of personal daily consumption limits: a useful intervention tool to promote responsible drinking among UK adults?

AIM: The aim of this study was to investigate the utility of a short, practical pouring exercise as a means of illustrating the details of the UK 'Sensible Drinking' guidelines.
METHODS: Participants (N = 297, 53% male) recruited at four Edinburgh employment sites, each completed a short non-standardized questionnaire and poured their 'usual measure of wine or spirit' into a glass (purchased from four 'high street' outlets). The actual and estimated unit content of their poured drinks and reactions to feedback were noted. Participants were informed of their daily limit of consumption in terms of this drink.
RESULTS: On average, drinks contained 2.05 UK units. Only 27% (N = 79) of respondents estimated the unit content of their drink within 10% of the true value. Of drinkers, 20.5% (N = 61) indicated that the results of the pouring test would influence their future pouring (70% of these were women). When informed of daily limits of consumption in terms of personal drink measure, 46% (N = 132) of drinkers indicated they would usually exceed this.
CONCLUSION: A practical demonstration of health guidelines presented in terms of personal drinking habits may contribute to dissemination of responsible drinking messages. Preliminary evidence suggests women may be particularly open to this approach. The utility of this intervention is underscored by recent figures highlighting the increasing preference for home drinking.
