Objectives: We aimed to evaluate use of a text message link to an online survey as a method of data collection over the course of a medical abortion.

Methods: We conducted a randomized, double-blinded, placebo-controlled trial of women initiating a medical abortion up to 70 days’ gestation. For data collection during this trial, electronic surveys were sent to participants via text message link at six specified time points over 72 h (baseline and 2, 6, 12, 24 and 72 h). Messages were automated through the Android application “SMS Scheduler,” sent from a phone dedicated to the trial and held by an investigator. The text provided a link to a secure online survey where participants could enter information without storing any data on their phones. Participants were remunerated with electronic gift cards for every survey response, with a bonus for completing all surveys.

Results: From June 2015 to October 2016, some 110 women were randomized. Three women (2.7%) were lost to follow-up after enrollment. Participants had a mean age of 27. Out of 241 women screened for inclusion, 3 (1.2%) were excluded due to lack of access to a cellular phone or the Internet. All six surveys were completed by 93.6% of participants. All women who responded gave a response at the 24-h mark. More than three quarters of all responses were received within 2 h of the requested time.

Conclusions: In this population of young women seeking medical abortions, a text message link to an online survey response appears to be an effective mode of longitudinal data collection.
