Evaluation of an Online Decision Aid for Selection of Contraceptive Methods.

OBJECTIVES: Knowledge gaps in contraceptives led to their low adoption rates and misuse in young women. The existing online contraception decision aids missed certain decision factors deemed important to college-aged women and did not consistently provide clear and accurate recommendations. To address the needs of young women and the limitations in current tools, we developed a prototype contraception decision aid, My Contraceptive Choice (MCC). This article reports an evaluation study of the MCC tool. METHODS: We conducted a mixed methods study: (1) to assess MCC's usefulness and usability through an online survey and a follow-up focus group, and (2) to provide a quantitative examination on the recommendations generated by MCC to match with individual user's needs and preferences through simulated test cases. RESULTS: The survey of 150 college-aged women showed very positive responses (reflecting personal preferences, 75%; helping people learn more about birth control methods, 88%; easy to navigate, 91%). The follow-up focus group of 10 survey participants reconfirmed most findings from the survey and provided detailed feedback on certain system functions, such as the inclusion of an important decision factor of weight gain and the efficient hybrid design to integrate the customized recommendations with the side-by-side comparison of all contraceptive methods. Simulated test cases showed that the MCC tool achieved an accuracy of 72% in addressing user preferences and an accuracy of 72% in satisfying user needs, which were significantly better than the existing Planned Parenthood tool. CONCLUSION: The initial evaluations suggest that the MCC tool has achieved good levels of usefulness, usability, and appropriate recommendations to address user needs and preferences. Future research is required to assess the performance of the MCC tool in naturalistic settings and to examine the generalizability of the findings to other user populations.

My Contraceptive Choice: A Decision Support Tool for College Women.

We developed an online decision aid, My Contraceptive Choice (MCC), for college women to select the appropriate birth control methods. MCC consists of a short quiz, customized recommendations, and educational resources. Evaluations from a focus group, an online survey, and test cases showed that the tool is accurate, usable, and useful. Future work is required to further improve MCC's compliance with user needs/preferences and to include additional resources to make it more useful.

Development of an Online Contraceptive Decision Aid for College Women.

Lack of knowledge in highly efficient contraceptive methods led to low rates of adoption and misuse of these methods by young women. The existing online tools for contraceptive decisions have flaws. To address this critical need, we developed a prototype online contraception decision aid for college women. For this purpose, we conducted a focus group interview for needs assessment. We designed a scoring system to provide accurate and customized recommendations based on a user's preferences. We implemented the tool with specific functions to collect users' needs and preferences in selecting specific contraceptive methods, to present the customized recommendations, to provide side-by-side comparison of all contraceptive methods, and to recommend additional resources. Preliminary data seem to indicate positive evaluations of the tool. Future work is required to examine the generalizability of the findings and to have full implementations of the tool for real world use.
