The intercultural development and validation of the Indigenous 'Escala de Bienestar Kankuamo' (Kankuamo Well-Being Scale): A capability approach.

This article describes the development and validation of a capability-based well-being scale: 'Escala de Bienestar Kankuamo' (EBK; the Kankuamo Well-Being Scale). The EBK is designed to measure the well-being of the Indigenous Kankuamo community of Colombia from an intercultural perspective. The mixed-methods study was composed of two phases. In phase I, an initial 27 items, which had been generated using qualitative data from a previous study, were reviewed and adjusted through workshops with the Kankuamo community. In phase II, an adapted list of 28 items was piloted within the Kankuamo communities (sample N = 213). A preliminary exploratory factor analysis was carried out. The internal consistency of the EBK was measured using McDonald's ω. Convergent and divergent validity were tested with the World Health Organization-Five Well-Being Index (WHO-5) and the Patient Health Questionnaire-9. Incremental validity was tested through a hierarchical regression analysis to determine the effect on the WHO-5 of age, gender, community and EBK. The exploratory factor analysis resulted in a 14-item scale with seven domains: (1) Relating (to others and one's emotions), (2) Guiding principles, (3) Choice of healthcare, (4) Self-grown food, (5) Community contributions, (6) Agency and (7) Respect and equality. The EBK had high internal consistency (McDonald's ω = 0.86). Statistical analyses aimed at determining the convergent and divergent validity were inconclusive, suggesting a need for caution in using western standardised mental health measures in Indigenous communities because these may lack adequate cultural fit. The findings of the current study identify local priorities and needs, and evidence the feasibility of operationalising the capability approach for Indigenous populations.
