Testing the Persuasiveness of Pro-inoculation Arguments

The investigators will recruit a national sample of parents of 7-10-year-olds to complete an argument strength ranking for either a simple forwarding message or between 3 and 6 randomly selected arguments from an overall set of 50 to 100 messages identified from various online sources. Parents will rate each message they see on measures of perceived argument strength/PME. Parents will also answer sociodemographic questions and then rank the believability of a set of anti-vaccine messages identified in a different study. Study findings will contribute valuable information to understanding the effectiveness of different inoculation messages.

Treatment and study plan

Argument inoculation messages

Behavioral

Participants will then be presented with arguments randomly selected by the Qualtrics software algorithm from the full set of messages.

Simple forewarning message

Behavioral

Participants will be presented with a simple forewarning message.

Primary outcomes

  1. Argument strength/PME

    Time frame: The outcome measure will be assessed immediately after the participant has viewed each pro-HPV vaccine message if they are in the multiple message condition, or the simple message if they are in the simple message condition stimuli during the survey.

    Arguments will be rated for their argument strength/message effectiveness

  2. Misinformation believability

    Time frame: The outcome measure will be assessed immediately after the participant has viewed each misinformation message during the survey.

    A rating of the believability/ credibility of vaccine misinformation
