Operationalising the Capability Approach for Healthy Child Growth via a Participatory Method: An Illustrative Case in Haor Areas of Bangladesh

The Task Force “Towards a Multidimensional Index to Child Growth”, within the International Union of Nutritional Sciences, developed a capability framework for child growth (CFCG). This framework aims to redefine child growth monitoring, expanding beyond weight and height to encompass parental capabilities. We further operationalised the CFCG in hard-to-reach haor areas of Bangladesh, resulting in the publication of a list outlining parental capabilities for child growth. This paper details the methodology and participatory process employed, offering reflections on how our research followed the criteria proposed by Robeyns for identifying capabilities. First, we built a contextualised list of capabilities for child growth based on discussions with local experts. This list underwent further adaptation for haor regions in two rounds. Initially, we used a doxastic interviewing methodology to create a draft emic list of capabilities for child growth. Subsequently, utilising an epistemic methodology, we refined the list. The doxastic interviews focused on “understanding” the interviewees; the epistemic interviews facilitated equal communication between interviewer and interviewee, promoting knowledge co-creation. This rigorous approach validates the findings with the affected communities and supports implementation of the CFCG in policy and practice. This methodology could be extended to other pertinent research areas for capability scholars.
