More reliable data for diarrhoeal intervention programmes: rethinking on knowledge, attitude and practice studies

The aim of this study was to propose an alternative approach to traditional knowledge, attitude and practice (KAP) studies to enhance the quality of data on which educational health programmes are based. The methodology proposed and illustrated involved a triangulation of approaches derived from linguistics, cognitive science, and medical laboratory sciences. Three diarrhoeal health talks (educational messages) as given to mothers in three primary-care facilities in Borno State (Northeast Nigeria) were subjected to a linguistics analysis. Relationships were then sought between the ontology of knowledge in the health talks as revealed by the text analysis and two other kinds of data, namely: (a) mothers' answers to a set of ecologically-sensitive reasoning questions that test how much relevant inferential knowledge the health talks allow for and (b) results of microbiological and biochemical analyses of salt-sugar rehydration solutions prepared by mothers participating in the study. The findings of the study show a relationship between contents/formatting of the health talks and the extent to which relevant inferential competence was supported or demonstrated by mothers. It was also evident that the laboratory analyses could be related either directly to the health talks or indirectly in terms of what the health talks need to emphasize on. The conclusion shows how the methodology proposed addresses shortcomings of traditional KAP studies in respect of the gap between health knowledge and practice.
