  Drafting of a narrative blueprint of the script for the health-awareness video is inspired by published and unpublished evidence-based studies previously conducted on public transportation drivers in Lebanon. This ensures the video content is evidence-based, culturally oriented, socially acceptable and tailored towards the target viewers. Using a Delphi technique, the script will be revised by a panel of experts in public health, infection control, psychology, filmmaking, and public transportation (drivers, users, stakeholders). Experts will evaluate the script using two validated assessment tools, the Patient Education Materials Assessment Tool (PEMAT) and DISCERN. Once consensus is reached, the video will be produced.

What is being measured

The primary outcome is the main question the study is designed to answer.

1. Knowledge

   Knowledge about RID mode of transmission and prevention will be evaluated (Khoury and Salameh 2015, Choucair, El Sawda et al. 2021). The percentage mean of knowledge scores (PMS±SD) will be presented. Higher scores indicate better knowledge. This variable measures the effectiveness of the health awareness video.

   Measured: 2 months

2. Patient Education Materials Assessment Tool - Audiovisual (PEMAT-AV) and • DISCERN tool

   PEMAT-AV systematically evaluates the understandability and actionability of educational materials. Understandability is the viewers' ability to understand the video regardless of their diverse backgrounds and varying levels of health literacy. Actionability is the viewers' ability to identify what they can do based on the information presented in the video regardless of their background and level of health literacy. PEMAT produces separate numeric scores for understandability and actionability.

   DISCERN: to enable information providers to judge the quality of information about treatment choices. DISCERN facilitates the production of new, high quality, and evidence-based consumer health information. DISCERN became a reliable and valid instrument for judging the quality of written consumer health information.

   Measured: 5 months

3. Health-risk perceptions

   Health-risk perceptions: participants' health-risk perceptions will be evaluated following two dimensions of the HBM that are the perceived susceptibility (2 items) and the perceived severity of RID (3 items) (Adams, Hall et al. 2014).

   Measured: 2 months

4. Attitude towards vaccination

   participants' attitude towards vaccination will be evaluated using three domains of the Vaccination Attitudes Examination (VAX) scale: unexplored side effects of the vaccines (5 statements), pharmaceutical companies profiteering from vaccines (3 statements), and preferred reliance on natural immunity (3 statements). VAX is a generic tool that identifies people with negative attitudes towards vaccines (Martin and Petrie 2017).

   Measured: 2 months

5. Cognitive dissonance

   dissonance is a self-reported measure of the emotional discomfort experienced due to cognitive dissonance (Elliot and Devine 1994). Cognitive dissonance can be measured using the dissonance thermometer that constitutes of adjectives distributed across four indices (discomfort index, negative self-index, shame index, and positive index). All four subscales demonstrated acceptable levels of reliability, with the positive and negative affect scales exhibiting excellent internal consistency and test-retest reliability (McGrath 2011). For this study, the discomfort index that constitutes of uncomfortable, uneasy, and bothered feelings will be used as adjective ratings (0 to 6). Higher score indicates an increased level of discomfort due to the effect of the video content.

   Measured: 2 months
