ABSTRACT
BACKGROUND: We are in the process of developing a new non-hormonal long-acting reversible method of contraception (LARC) in recognition of the fact that a significant minority of users are unhappy with their current method. Our method has a novel (post-fertilisation) mechanism of action (MOA), but little is known about the value users place on this. METHODS: Using in-depth interviews, we explored 30 Australian end-users' experiences of contraception, recruited via social media. A thematic approach was taken to examine the influence the MOA has on choice and factors affecting willingness to try current methods and a novel non-hormonal LARC with a post-fertilisation effect. RESULTS: We identified two themes that were the most salient across all interviews: that contraceptive decision-making involves a trade-off of priorities, influenced by contraceptive properties (including MOA) and the context in which contraception is used; and views on novel methods of contraception were influenced by willingness to trial new products and interest in non-hormonal options. Side effects, efficacy, and the financial burden of contraceptives were all considered more important than MOA during decision-making. Participants were willing to try a new method if endorsed by trusted sources, including friends and medical practitioners, and were enthusiastic to try a novel LARC with no hormones. CONCLUSION: This study found that the MOA had minimal impact on participants' choice of contraception. Rather, avoidance of hormones and side effects influenced willingness to try a novel method over any unacceptable aspects of a post-fertilisation MOA.
