Knowledge Mobilization Activities to Support Decision-Making by Youth, Parents and Adults: Study Protocol

The primary outcome is understanding. Understanding is defined as the correct comprehension of key guideline content (year of publication, intent of the recommendation, direction of recommendation, etc.). This outcome will be measured with seven multiple-choice questions about key concepts in the recommendation with four to six response options for each question and only one correct answer (total minimum score of 0, maximum score of 7).

Accessibility and Usability is defined as the ability to find/access, and use the presented information. This outcome considers the three following domains: (1) how easy it was to find information, (2) how easy it was to understand the information (perception), and (3) whether the information was presented in a way that could be helpful for making an informed health decision. Participants will have to indicate the degree of agreement with six statements, measured using the original 7-point Likert scale (1 being strongly disagree, 4 being neutral, and 7 being strongly agree). The outcome 'overall accessibility of information' will be measured using the 7-point Likert-type scale.

Satisfaction is defined as participants' impression of the recommendation's presentation. This will be measured using questions related to participants' level of satisfaction with the different features of the format (e.g. feature of explaining the certainty of the evidence). Participants will have to indicate the degree of satisfaction with three questions measured using the original 7-point Likert-type scale (11 = very dissatisfied, 2 = dissatisfied, 3 = somewhat dissatisfied, 4 = neutral, 5 = somewhat satisfied, 6 = satisfied, 7 = very satisfied). Participants will also have to answer three open-ended questions to get their input on what they liked and disliked in the format.

Intended behavior is defined as participants' intention in adopting and following the shared recommendation. Participants will answer a question on whether they have already followed and implemented the recommendation in their jurisdiction and have them respond with yes, no, unsure, or not applicable. Subsequently, they will be asked how likely it is that they will follow and share the recommendation through two questions measured using a 7-point Likert-scale (1 = very unlikely, 2 = unlikely, 3 = somewhat unlikely, 4 = neutral, 5 = somewhat likely, 6 = likely, 7 = very likely.

Preference is defined as a greater liking of one format over the other (PLR or SLV). All participants will get to compare the optimized PLR and the SLV; after having completed the tasks in the group they were randomized to, participants will review the alternative format and indicate their preference for one of the two formats using a 7-point Likert-type scale (1 = strongly prefer SLV, 2 = prefer SLV, 3 = somewhat prefer SLV, 4 = same preference for SLV and PLR, 5 = somewhat prefer PLR, 6 = prefer PLR, 7 = strongly prefer PLR).
