Hall, Kelli Stidham, Paula Castano, and Carolyn Westhoff. 2013. "The impact of an educational text message intervention on young urban women's knowledge of oral contraception." Contraception, 87(4): 449-454.
Background: Oral contraceptive (OC) knowledge deficits may contribute to OC discontinuation. We examined the effect of an innovative educational intervention on young women's OC knowledge. Study Design: As part of a randomized trial evaluating the impact of text message reminders on OC continuation, we assessed OC knowledge in 659 women ages 13-25 years. Women received routine care or routine care plus 6 months of daily educational text messages. We administered a comprehensive 41-item OC knowledge survey at baseline and 6 months. Results: Mean OC knowledge scores improved over time for all women (baseline 22.8, 56% correct versus 24.7, 60% at 6 months), including knowledge of OC's mechanisms of action (p=.004), effectiveness (p<.001), side effects (p=.03) and benefits (p<.001). Mean 6-month scores were greater in the intervention (25.5) than the control group (23.7)(p<.001). In multivariable linear regression models, the text message intervention most strongly predicted OC knowledge (β= 1.6, 95% confidence interval 0.9-2.2). Conclusion: Daily educational text messages can modestly improve knowledge of OCs, which may promote successful contraceptive outcomes. © 2013 Elsevier Inc.
