The Diamond Dialogue has previously been used as a research tool, as a way of evaluating the effectiveness of development of interventions in changing quality of life in a variety of contexts. This paper aims to describe the development of the Diamond Dialogue as a community intervention tool to reduce alcohol-related harm. This was part of an action research study. Focus groups, using the Diamond Dialogue, were conducted during workshops to reduce alcohol-related harm in two different villages. The Diamond Dialogue was initially used as a tool to better understand how drinking was affecting their quality of life. The Diamond Dialogue was intentionally used as part of the intervention in one village, with the discussion on alcohol and quality of life leading into discussion on community level change to reduce alcohol-related harm. The discussion notes were analysed for themes related to quality of life and alcohol use. Alcohol was seen by community members to have both positive and negative effects on the community. Using the Diamond Dialogue as an intervention lead to greater levels of engagement, created a collective motivation to change and led to community level action planning. Exploring community ambivalence towards alcohol, acceptance of both the positive and negative effects and validation of the community’s views provided a platform for engagement. This then lead to “change talk” about adopting low-risk drinking and ownership of possible solutions for alcohol related problems.
