A Decision Aid for Postpartum Adolescent Family Planning: A Quasi-Experimental Study in Tanzania

Background: We evaluated the effects of our postpartum Green Star family planning decision aid on the decisional conflict, knowledge, satisfaction, and uptake of long-acting reversible contraception among pregnant adolescents in Tanzania. Methods: We used a facility-based pre–post quasi-experimental design. The intervention arm received routine family planning counseling and the decision aid. The control received only routine family planning counseling. The primary outcome was the change in decisional conflict measured using the validated decision conflict scale (DCS). The secondary outcomes were knowledge, satisfaction, and contraception uptake. Results: We recruited 66 pregnant adolescents, and 62 completed this study. The intervention group had a lower mean score difference in the DCS than in the control (intervention: −24.7 vs. control: −11.6, p < 0.001). The mean score difference in knowledge was significantly higher in the intervention than in the control (intervention: 4.53 vs. control: 2.0, p < 0.001). The mean score of satisfaction was significantly higher in the intervention than in the control (intervention: 100 vs. control: 55.8, p < 0.001). Contraceptive uptake was significantly higher in the intervention [29 (45.3%)] than in the control [13 (20.3%)] (p < 0.001). Conclusion: The decision aid demonstrated positive applicability and affordability for pregnant adolescents in Tanzania.
