Abstract:
The purpose of this study was to examine the effect text messages (TM) immunization reminders have on immunization rates in the first 7 months of life. This randomized-control trial enrolled 57 parent/infant dyads and had a 74% completion rate (43) at the end of the study period. The study was approved by Committee on Human Subjects at the University of Hawaii Institutional Board Review. All participants completed a demographics form and a Barriers to Immunization Survey (SHOTS survey) at the start and end of the study. Parents received TM at 4, 7, 12, 15, 20, & 23 weeks of child's age. The intervention group received immunization reminders and the control group received healthy baby messages. In the overall mixed model, between enrollment and 7 months of age, the barriers to immunizations decreased for all parents significantly. There were no significant differences in immunization rates between groups at 7 months of age. Positive responses from regarding TM interventions show this is a promising intervention, but further research is required regarding how to address behavior change and motivation for health prevention behaviors with TM.
