Descripción detallada
The purpose of this activity is to identify promising cannabis warning messages from different themes.
Setting: An online survey of adults who live in the United States.
Participants: An estimated N=1500 adults who live in the United States, including both people who use cannabis and those who do not use cannabis. Participants will be recruited by Qualtrics Services. Participants who are eligible for the study will view a consent form as part of the survey and check a box to indicate that they agree to participate in the study. Once the participant has completed consent, they will be able to begin the survey.
Procedures: Participants will complete a within-subjects experiment in which they view and rate cannabis warning messages from different themes. Participants will be screened for inclusion and answer questions on demographic information and susceptibility to cannabis use. Participants will then be randomly assigned to view 7 cannabis warning messages from different themes developed as part of previous study activities. After viewing each cannabis warning message, participants will rate the message on awareness, clarity, believability, cognitive elaboration, perceived message effectiveness, and reactance. There will be a total of 11 warning themes plus control. After viewing and rating their assigned cannabis warning messages, participants will answer additional questions about cannabis risk perceptions and use behavior (if applicable), additional demographic information, and about their use of tobacco and alcohol. The survey will take 15-20 minutes.
