Acceptability and proactive intervention use
Acceptability of interventions and proactive intervention use (i.e., clicking on a hyperlink on the study page to access the intervention) were assessed in study arms 1 to 3 only. Acceptability was high across all arms, with more than 80% of participants in all study arms indicating that they would recommend the intervention (Video, Questions, or both) to others. However, only a small number of participants from the study in each arm proactively accessed the intervention after the study (range: 1.7%–20.8%). This was highest for the Questions arm both immediately postintervention and at 2-wk follow-up. See
