Questionnaires and educational interventions
Two sets of anonymous surveys were distributed in this study. The first set of surveys (pre-survey and post-survey) were collected Dot plot representing survey completion dates. Each dot represents one participant. The pre- and post-survey completion dates are indicated in blue. The follow-up survey completion dates are indicated in orange.Survey flow. Three parts of the survey, illustrated under the tan-colored rectangle, were completed during one sitting. First, each participant completed the pre-survey, which included demographic and COVID-19 questions. Next, the participants were randomized to receive either a video or infographic educational intervention. Finally, the participant completed the post-survey, which included COVID-19 questions. Three months later, the participants received a follow-up survey, which included COVID-19 questions.The second survey set included a 3-month follow-up survey. After completion of the first survey, patients were offered to complete the second survey, which could be completed at home. Those that elected to complete this portion of the study created a unique identification number to maintain anonymity and to match the first set of surveys with their 3-month follow-up survey. Emails were collected from patients who were interested in completing the follow-up survey. To incentivize completion of the follow-up survey, participants received a $10 digital gift card sent to their email upon completion of this survey. The follow-up survey was distributed to patients at least 3 months after the completion of the first set of surveys. The follow-up survey prompted participants to provide updated vaccination status, provide any learning about COVID-19 or the vaccine that may have occurred since the educational intervention, and included the same COVID-19 knowledge and attitude questions from the pre- and post-intervention surveys. If answered “YES” to the question asking about new information learned since the educational intervention, a drop-down area for participants to type what they had learned appeared. Otherwise, all other questions consisted of multiple-choice questions and the three-point Likert scale questions previously described. This questionnaire also utilized Qualtrics Online Survey Platform.
