简要总结

The goal is to identify the most impactful strategies for capturing attention and enhancing effectiveness of vaccine promotion messages. This will be done using an online survey that employs remote eye-tracking and self report measures to evaluate response to sample vaccine promotion social media content in rural populations in New England. Participants will be randomly assigned into one of 14 conditions in a 2(source: expert vs. influencer) by 7 (themes: constructs from 7C Vaccine Framework) experiment and view sample messages and then answer questions about their attitudes and beliefs while being monitored for eye-tracking.

结局指标

主要结局

Source credibility

时间窗: Immediately after viewing each message

Participants' perception of the credibility of the message source will be assessed using a 7-point Likert scale measured across four items. Participants will be asked to rate the following four items on this scale: To what extent do you believe the source of the message to be… (1=not at all, 7=very much so) 1. Fair 2. Accurate 3. Telling the whole story 4. Trustworthy Unit of measure: Scale score 1-7, mean

Perceived Message Effectiveness

时间窗: Immediately after viewing each message

Perceived message effectiveness will be measured using six items (worth remembering, grabs attention, powerful, informative, meaningful, convincing), each rated on a 7-point Likert scale. The outcome will be the mean of these six ratings for each participant, then averaged by experimental condition. To what extent is… (1=not at all, 7=very much so) 1. The message worth remembering 2. The message grabs attention 3. This message powerful 4. This message informative 5. This message meaningful 6. This message convincing Unit of Measure: Scale score (1-7, mean across items)

Visual attention

时间窗: During message viewing ( immediately post-randomization, prior to completion of post-message survey)

Visual attention, quantified as mean dwell time in milliseconds, will be measured using remote eye-tracking while participants view vaccine promotion messages. Dwell time will be calculated for pre-specified Areas of Interest (AOIs) during the message viewing period. Higher dwell times indicate greater visual attention to the AOIs. Unit of measure: mean dwell time in milliseconds per message

Message reactance

时间窗: Immediately after viewing each message

Reactance will be assessed using four items (irritated, angry, annoyed, aggravated), rated 0 ("None of this feeling") to 4 ("A great deal of this feeling"). The mean reactance score will be calculated for each participant. How much did this message make you feel the following way? Response options: 0 (None of this feeling) to 4 (A great deal of this feeling). 1. Irritated 2. Angry 3. Annoyed 4. Aggravated Unit of Measure: Scale score (0-4, mean across items)

Information sharing intentions

时间窗: Immediately after viewing each message

Description: Assessed with 6 items regarding interpersonal and online sharing, rated 1 (Strongly disagree) to 5 (Strongly agree). The mean score across items will be reported per participant and per condition. Rate with the following statements on a scale from 1 (Strongly disagree) to 5 (Strongly agree). Interpersonal setting 1. I would be willing to share this information with others. 2. I would talk with others about this message. 3. I would point others in a direction where they could read this message. Online setting 4. I would be willing to post a link to this information on my social media. 5. I would like a social media post with this information. 6. I would share a social media post with this information. Unit of Measure: Scale score (1-5, mean across items)

次要结局

  • Vaccine perceptions(Assessed at baseline (prior to message exposure) and immediately post-intervention (after message exposure))
