In total, 20 participants were recruited for a one-month intervention involving the use of cell phones to text pregnancy-related questions to the system. Participants received either a direct answer or encouragement to seek answers from health care providers. Pre- and post-tests as well as a focus group at the end of the intervention were conducted.
Participants uniformly found the system easy to use and accessible. Using the system increased levels of perceived pregnancy-related knowledge and facilitated patient-provider communication. Moreover, participants reported significant reductions in stress and depression and improved mental health after using the system. The system responded to most known questions quickly and accurately, and also encountered many new topics and linguistic expressions.
Overall, the data indicated that the text messaging system offered psychological benefits and promoted health communication by providing health information and encouraging patient-provider communication.
An automated, two-way text messaging system is an efficient, cost-effective, and acceptable method for providing health information to low-income pregnant women.
