Self-Management Using Text Messaging in a Homeless Population

"Subjects will receive text messages with reminders of their upcoming outpatient health care appointments at the Boston Health Care for the Homeless Program (BHCHP) clinic. The text message will indicate the time of the appointment and the location (e.g. Remember appointment Friday March 15 at 10am in the Yawkey building). Appointment reminder text messages will be sent 3 days ahead and again 1 day ahead of the appointment date. Medication related texts will be sent every other day and will be educational and motivational (e.g. Keep taking medications that way the doctor prescribed them, even if feeling fine). Mood related texts will also be sent every other day and ask about mood on a 1 to 5 scale. The participant will text back a response."
