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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>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.<\/jats:p>\n
