Study Arms (4)

Control Reminder

EXPERIMENTAL

Eligible, randomized participants will receive a generic text message reminding them to close their outstanding health gap.

Behavioral: Reminder of preventive care measures

Anecdote-based Reminder

EXPERIMENTAL

Eligible, randomized participants will receive a text message reminding them to close their outstanding health gap. This message will contain an anecdote of a patient whose cancer was caught early through similar, recommended preventive screenings. The message prompts patients to click on a link to read the story about the patient.

Behavioral: Reminder of preventive care measuresBehavioral: Persuasion via anecdote

Anecdote-based Reminder without link

EXPERIMENTAL

Eligible, randomized participants will receive a text message reminding them to close their outstanding health gap. This message will contain an anecdote of a patient whose cancer was caught early through similar, recommended preventive screenings. The message won't contain a link to the story, but it will briefly describe the story.

Behavioral: Reminder of preventive care measuresBehavioral: Persuasion via anecdote without link

Research-based Reminder

EXPERIMENTAL

Eligible, randomized participants will receive a text message reminding them to close their outstanding health gap. This message will mention that research has shown promptly closing health gaps saves lives. The message will contain a link to an official website that supports the statement.

Interventions

The investigators will send randomized participants an SMS reminder encouraging them to click the provided link and close their outstanding, overdue preventive care measures. The provided link will take them to their MyChart login page; after logging in, they would see their personalized My Action Plan Letter detailing their personalized, overdue preventive care measures.
