What this Trial Is About
This research aims to evaluate the effectiveness of personalized and general text messages on encouraging participants with high LDL cholesterol to visit their general practitioner (GP). The study runs alongside a larger study called RESET and seeks to understand if personality-tailored advice improves adherence to GP consultations compared to general messages or no intervention. Participants will receive one of three interventions embedded in their return of results emails: a personalized message tailored to their personality traits, a general health message, or no message as a control. Both message types include information on lipid therapy indications, benefits, side effects, risks of non-adherence, and lifestyle infographics. Messages are delivered only once when participants receive their LDL-C results. Participants are involved by completing two questionnaires, one before and one after receiving their results. Researchers will measure intentions to adopt healthier diets, engage in physical activity, and visit a GP over a period of three months following result return. The study monitors these outcomes without masking or blinding, with participation expected to last up to three months after results are shared.
