Our aim was to develop a culturally competent and safe tool to assess and promote well-being among this population. We followed a qualitative, collaborative, and participatory method that sought to benefit Indigenous participants and communities, while honouring their culture and philosophies. Twelve adults from health and community services of Kahnawà:ke participated in total five focus group meetings. We carried out a thematic analysis of the data collected through an advisory group that led a revision of the cultural and conceptual relevance of the tool and its content. The group integrated socio-culturally relevant elements and restructured the tool so that it reflected local well-being factors and showed its versatility of being an assessment tool and therapeutic support. A narrative and empowerement-driven approach, culturally based intervention, cultural safety and flexibility when using the instrument were considered successful strategies to improve wellness. This project provides valuable information about the perspectives of local Indigenous communities regarding mental health and factors of empowerment. Mutual understanding and integration of psychological and traditional knowledge can create a beneficial program to improve emotional, mental, spiritual, and physical well-being for the local population. It remains to be tested whether the Kanien'kehá:ka Growth and Empowerment Measure (K-GEM) is clinically useful in psychological and psychiatric intervention, and social and community services.
