Disentangling health information appraisal competence: Results from an interdisciplinary scoping review and online consultation among Swiss stakeholders

BACKGROUND: The ability to critically appraise health information–often referred to as critical health literacy–is recognized as a crucial component of health literacy. Yet to date, it is not clear what specific abilities are needed to adequately accomplish this task, thereby hindering both its assessment and the development and evaluation of related interventions. By systematically building on past research, this study aimed to operationally define the concept of health information appraisal competence. METHODS: We systematically searched five scholarly databases to identify the conceptualizations and operational definitions of information appraisal in different disciplines. The resulting operationalization was subsequently validated through an online consultation exercise among 85 Swiss stakeholders. RESULTS: Ninety-four publications were included in the review to the point of saturation. We extracted 646 skills, attitudes, and knowledge for health information appraisal. We then collated overlapping or duplicate statements, which produced a list of 43 unique statements belonging to six emergent themes or core competences: (1) basic competence, (2) predisposition, (3) identification competence, (4) critical evaluation competence, (5) selection competence, and (6) application competence. The consultation exercise enriched the operationalization of some of the core competences and confirmed the importance of all competences. Most skills, attitudes, and knowledge, however, were assigned low feasibility by the stakeholders. CONCLUSIONS: This study was the first attempt to systematically operationalize health information appraisal competence. From a theoretical perspective, it sheds light on an understudied, health literacy domain, thus contributing to clarity around the concept. From a practical perspective, it provides a strong theoretical basis for the development of a tool to measure health information appraisal competence. This could be used routinely as a screening tool, as an outcome measure for public health interventions, or to identify citizens who are most at risk. Furthermore, it will provide support for the development of future interventions to build health information appraisal competence in the population.
