Mixed Presentation on Social Media

This study is to understand how the presentation of information on social media influences processing and recall of information, particularly in relation to modified risk tobacco products. Participants will see a social media site where either (a) the topic of discussion varies between each post or (b) posts on the same topic are grouped together. They will then be asked to recall information about the posts they saw on the site.

Treatment and study plan

Mixed-Presentation of Content

Behavioral

Participants in the high-mixed presentation of content conditions will receive a social media feed that varies greatly between topics, so that each subsequent post is on a different topic. In the low-mixed presentation of content condition, participants will be shown posts on any given topic grouped together.

Primary outcomes

  1. Recall of precise information

    Time frame: During experiment

    Binary outcome as to whether the individual can recognize the specific text from a social media post as having appeared or not appeared on the social media site.

  2. Recall of general information

    Time frame: During experiment

    Binary outcome as to whether the individual can recognize the content from a social media post as having appeared or not appeared on the social media site, but not necessarily the specific wording used.

  3. Recall of source category

    Time frame: During experiment

    Binary outcome as to whether the individual can recognize the type of source (e.g. government/media) that presented a piece of information on the social media site.

  4. Recall of precise source

    Time frame: During experiment

    Binary outcome as to whether the individual can recognize the exact source that presented a piece of information on the social media site.

Secondary outcomes

  1. Attention paid during use of the site (self-report)

    Time frame: During experiment

    A series of questions pertaining attention paid during use of the social media site. These are then combined into a single self-report measure.

  2. Attention paid during use of the site (behavioral)

    Time frame: During experiment

    Time spent consuming relevant posts on the social media site between conditions.

  3. Attitude towards smoking cessation

    Time frame: During experiment

    Change in the interest in smoking between the pre- and post-test among current smokers. Measured with one self-report item.

  4. Attitude towards novel tobacco products

    Time frame: During experiment

    Attitude/interest in trying alternative tobacco products (e.g. e-cigarettes, heated tobacco) in the post-test.

  5. Belief of heated tobacco safety

    Time frame: During experiment

    Measure of how safe the individual believes heated tobacco is in comparison to cigarette use.
