  "abstract": "Background: Coronary heart disease (CHD) is the leading cause of cardiovascular mortality worldwide, and its management requires patients to make complex, preference-sensitive treatment decisions. Decisional conflict is common in this population and adversely affects treatment adherence and outcomes, yet its association with eHealth literacy and the underlying psychological mechanisms remain unclear.\n\nObjective: This study examined the association between eHealth literacy and decisional conflict in patients with CHD, tested the chain-mediating roles of cyberchondria and psychological inflexibility, and identified latent profiles of eHealth literacy.\n\nMethods: A cross-sectional design was employed, and patients with CHD were recruited from tertiary Grade A hospitals. The survey battery comprised the eHealth Literacy Scale, the Decisional Conflict Scale, the Cyberchondria Severity Scale, the psychological inflexibility subscale of the Multidimensional Psychological Flexibility Inventory, and requisite demographic items.\n\nResults: eHealth literacy was significantly and negatively associated with decisional conflict, and this association was mediated by cyberchondria and psychological inflexibility. From a person-centered perspective, two latent subgroups of eHealth literacy were identified: a high eHealth literacy profile and a low eHealth literacy profile. One-way analysis of variance indicated that the optimal latent profiles differed significantly in decisional conflict, cyberchondria, and psychological inflexibility.\n\nConclusion: This study not only helps identify priority targets for interventions addressing decisional conflict in patients with CHD, but also elucidates the psychological pathways through which eHealth literacy shapes treatment decision-making, thereby informing heterogeneity-informed, tailored clinical interventions.",
