The practice of information appraisal: An ethnographic study of a health information intervention.

As healthcare systems grow increasingly complex, greater demands are placed on patients' abilities to find, understand, appraise, and use health information - often termed their 'health literacy'. Most health literacy research does not focus on information appraisal. When it does, there is a tendency to equate it with patients' assessment of credibility. This reproduces a healthcare-centric understanding of information appraisal where patient agency is omitted. This study explores how participants in a health information intervention practiced information appraisal. The intervention aimed to increase information uptake for people with low back pain by delivering health information to them through animations. This study draws on ethnographic participant observation of the encounters between the intervention and its participants, including 49 rapid interviews and semi-structured telephone interviews with 23 participants carried out in the spring of 2021. Inspired by a social practice approach, the study thoroughly grounds the health literacy subcategory of 'appraisal' in practice. It illustrates that participants appraised the information provided in the intervention according to several factors. These include relating the information to their personal health needs, interpreting the intended audience of the health animations, and prioritising their attention situationally between the animations and other immediate concerns. We suggest that information appraisal is a fundamental component of health literacy and should be considered key in research, policy and practice. To accommodate current healthcare ideals of patient centeredness, empowerment and informed choice, the complex and dynamic ways in which people appraise health information need be considered legitimate practices of health literacy.
