Educational Articles Delivery
Reading behaviors
SECONDARY
For educational articles, the dose delivered and received were reported. During month 1, 21 selected articles were delivered to all participants in the intervention group. As data on whether the participants unsubscribed to the platform were not available, we presumed that all the articles were delivered as planned.We used access to educational article links as a proxy for reading behavior. The dose received was measured by the number of access and access:delivery ratio (the number of access divided by the number of articles delivered) by article theme. Reading behaviors for primary and secondary categories were also constructed to assess the engagement of the participants. Reading behaviors were categorized as very high reading (ie, accessing every article delivered in month 1 at least once), high reading (ie, accessing only some of the articles with access:delivery ratio >1), adequate reading (ie, accessing only some of the articles with access:delivery ratio <1), and no reading engagement (not reading any of the articles in the specific category).
