Summary
This study will send different types of WhatsApp messages to 235,000 people in Chile who are due for cancer or chronic disease screenings. Researchers want to see if the way a message is worded (basic, risk-focused, or peace-of-mind) and whether it mentions one test or both tests together makes people more likely to schedule their appointments. The goal is to find the best way to encourage preventive care.
