Mixed Presentation on Social Media

Study Overview
=================
Brief Summary
-----------------
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.

Design Details

Primary Purpose: Basic Science
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Participants are assigned to one of two between-group conditions: either receiving a high mixed presentation of content in the social media feed (where the topic varies from post to post), or a low mix of presentation of content in the social media feed (where the topic does not vary). Additionally, two further between-subject groups will be created by independently examining effects among current and former smokers.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: High-Mixed Presentation / Current Smoker<br>Current smokers receive a social media feed with a high-mixed presentation of content. | Behavioral: Mixed-Presentation of Content<br>* 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.<br>|
| Experimental: Low-Mixed Presentation / Current Smoker<br>Current smokers receive a social media feed with a low-mixed presentation of content. | Behavioral: Mixed-Presentation of Content<br>* 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.<br>|
| Experimental: High-Mixed Presentation / Former Smoker<br>Former smokers receive a social media feed with a high-mixed presentation of content. | Behavioral: Mixed-Presentation of Content<br>* 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.<br>|
| Experimental: Low-Mixed Presentation / Former Smoker<br>Former smokers receive a social media feed with a low-mixed presentation of content. | Behavioral: Mixed-Presentation of Content<br>* 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.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Recall of precise information | 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. | During experiment | 
| Recall of general information | 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. | During experiment | 
| Recall of source category | 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. | During experiment | 
| Recall of precise source | Binary outcome as to whether the individual can recognize the exact source that presented a piece of information on the social media site. | During experiment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Attention paid during use of the site (self-report) | A series of questions pertaining attention paid during use of the social media site. These are then combined into a single self-report measure. | During experiment | 
| Attention paid during use of the site (behavioral) | Time spent consuming relevant posts on the social media site between conditions. | During experiment | 
| Attitude towards smoking cessation | Change in the interest in smoking between the pre- and post-test among current smokers. Measured with one self-report item. | During experiment | 
| Attitude towards novel tobacco products | Attitude/interest in trying alternative tobacco products (e.g. e-cigarettes, heated tobacco) in the post-test. | During experiment | 
| Belief of heated tobacco safety | Measure of how safe the individual believes heated tobacco is in comparison to cigarette use. | During experiment |
