The Science of Absent Evidence: Is There Such Thing as an Effective Responsible Drinking Message?

摘要

Aims: We conducted a systematic literature review of studies evaluating the effectiveness of responsible drinking messages (RDMs). Methods: We searched PsycINFO, MEDLINE, and Google Scholar to June 2016 for studies evaluating the effectiveness of RDMs. Only eight studies met the inclusion/exclusion criteria. Due to a small number of search results and broad inconsistency in methods and outcome measures, quantitative synthesis was not possible so a narrative summary of findings was conducted. Results: A review of findings from these articles suggested a disjointed approach in terms of the format and content of RDMs evaluated, as well as the dependent variables used to judge their effectiveness. An overall pattern emerged suggesting that RDMs may have beneficial effects across various outcome measures, including reducing prospective alcohol use. However, due to the inconsistent approach to both the development and evaluation of RDMs, it was not possible to draw any clear conclusions in terms of effectiveness, or indeed the potential size of any effects. Conclusions: A systematic approach to the development and evaluation of RDMs is recommended to ensure that a clearer evidence base is established in this area, particularly in light of the substantial public funds which are often spent on RDM campaigns.
