Purpose: This paper presents the use of the Group Analysis Method (GAM), an innovative method developed in a francophone context, to discuss issues related to the services offered in the field of addiction in Quebec's Indigenous communities and to identify perspectives for innovative solutions. Design/methodology/approach: This article begins with a detailed description of the method's phases and steps based on the French-language writings of the developers of the GAM. The authors then illustrate a concrete example of how this method has been applied to addiction intervention stakeholders in Indigenous communities in Quebec (Canada), highlighting the type of results possible. Findings: The strengths and weaknesses of the GAM for addressing sensitive issues in an Indigenous context are discussed. Recommendations for further integration of the Indigenous perspective into the approach are proposed. Originality/value: This article presents a relevant qualitative method for co-constructing solutions with groups which, to our knowledge, has not been described in the English-language literature. In the light of their experience in an Indigenous context, the authors adopt a critical perspective, demonstrating the relevance of the method and suggesting adaptations to ensure an equitable distribution of power through the process.
