(2016). Alcohol’s harm to others: An international collaborative project. The International Journal Of Alcohol And Drug Research, 5(2), 25-32. doi:http://dx.doi.org/10.7895/ijadr.v5i2.218Aims: This paper outlines the methods of a collaborative population survey project measuring the range and magnitude of alcohol’s harm to others internationally.Setting: Seven countries participating in the World Health Organization (WHO) and ThaiHealth Promotion Foundation (ThaiHealth) research project titled “The Harm to Others from Drinking,” along with two other countries with similar studies, will form the core of a database which will incorporate data from other countries in the future.Measures: The WHO-ThaiHealth research project developed two comparable versions of a survey instrument, both measuring harm from others’ drinking to the respondent and the respondent’s children.Design: Surveys were administered via face-to-face methods in seven countries, while similar surveys were administered via computer-assisted telephone interviews in two additional countries. Responses from all surveys will be compiled in an international database for the purpose of international comparisons.Discussion: Harms from the alcohol consumption of others are intertwined with the cultural norms where consumption occurs. The development of this database will make it possible to look beyond reports and analyses at national levels, and illuminate the relationships between consumption, harms, and culture.Conclusions: This database will facilitate work describing the prevalence, patterning, and predictors of personal reports of harm from others’ drinking cross-nationally.
