"Necesita una vacuna": what Spanish-speakers want in text-message immunization reminders.

Appointment reminders help parents deal with complex immunization schedules. Preferred content of text-message reminders has been identified for English-speakers. Spanish-speaking parents of children under three years old were recruited to develop Spanish text-message immunization reminders.

Parent opinions about use of text messaging for immunization reminders.

Background: Adherence to childhood immunization schedules is a function of various factors. Given the increased use of technology as a strategy to increase immunization coverage, it is important to investigate how parents perceive different forms of communication, including traditional means and text-message reminders.

Objective: To examine current forms of communication about immunization information, parents' satisfaction levels with these communication modes, perceived barriers and benefits to using text messaging, and the ideal content of text messages for immunization reminders.

Using human factors techniques to design text message reminders for childhood immunization.

This study engaged parents to develop concise, informative, and comprehensible text messages for an immunization reminder system using Human Factors techniques. Fifty parents completed a structured interview including demographics, technology questions, willingness to receive texts from their child's doctor, and health literacy. Each participant was assigned to one user-centered design test: card sort, needs analysis, or comprehension.
