Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will recruit subjects online and randomly assigned them to one of four arms. The arms vary by clinical decision (colorectal cancer screening or treatment of high cholesterol) by video order (poor shared decision making followed by good or good shared decision making followed by poor). Participants will view two videos and complete the Shared Decision Making process survey along with a few other measures after each video. Our main hypothesis is that respondents watching the good shared decision making videos will score higher on the Shared Decision Making Process survey compared to those watching the poor videos.
