Researchers conducted a randomized pilot evaluation study. All participants were pregnant women first presenting for care at the Fairfax County, Virginia Health Department. They randomized participants to enroll in text4baby and receive usual health care (intervention), or continue simply to receive usual care (control). A 24-item survey by telephone was conducted of attitudes and behaviors related to text4baby. Participants were surveyed at baseline, before text4baby was delivered to the intervention group, and at follow-up at approximately 28 weeks of baby’s gestational age.
Researchers completed 123 baseline interviews in English and in Spanish. Overall, the sample was predominantly of Hispanic origin with an average age of 27.6 years. 90 follow-up interviews were completed, and achieved a 73% retention rate.
The researchers found a significant effect of text4baby intervention exposure on increased agreement with the attitude statement “I am prepared to be a new mother” between baseline and follow-up. For those who had attained a high school education or greater, we observed a significantly higher overall agreement to attitudes against alcohol consumption during pregnancy. They also observed a significant improvement of attitudes toward alcohol consumption from baseline to follow-up.
This pilot study is the first randomized evaluation of text4baby. It is a promising program in that exposure to the text messages was associated with changes in specific beliefs targeted by the messages.
