While online medical consultations (OMCs) have become increasingly popular, not least in times when epidemics make access to medical facilities difficult, research exploring the interactive value of OMC is still in its infancy. This study examines patients’ disalignment with speculative diagnosis and its management by doctors in OMC interactions, which to my best knowledge are not examined. From a discourse analytic perspective, this study adopts Du Bois’s notion of stance-taking to approach text-based interactions collected from a widely used OMC website in China. This study finds that patients’ disalignment is often based on hard evidence, which is different from the major findings of previous studies. When addressing such disalignment, doctors adopt varied discursive strategies, which are hardly mentioned in prior studies, in particular, strategies that address the affective aspect of patients’ disalignment. This study thus provides a different perspective on disalignment and its management in the clinical context.
