简要总结
This study evaluates the effectiveness of behavioral messages sent via WhatsApp in encouraging patients to schedule preventive dental check-ups. Specifically, it examines how (1) prompting people to bundle the dental appointment with an existing medical visit and (2) price discounts influence scheduling behavior.
详细描述
Patients in this trial will be randomized in equal numbers to one of five conditions: One Holdout condition where patients do not receive any WhatsApp message or communications about dental check-ups, or one of four treatment conditions.
The treatment conditions comprise a 2×2 factorial design:
- Bundling: Whether the message emphasizes the option to schedule the dental check-up on the same day as an already scheduled medical appointment
- Price: Whether the price offered is $990 or $19,990 CLP
All four message conditions will receive a WhatsApp message offering a full preventive dental check-up with X-rays, with the price of the check-up specified according to the assigned price condition. For patients in the bundling frame conditions, the message will also highlight the opportunity to save time by scheduling the dental check-up on the same day as their upcoming medical appointment.
We ask the following research questions:
