The vaginal diaphragm is a candidate for a female-controlled method of reducing risk of HIV/STI acquisition. We examined the association between relationship and partner factors and three measures of diaphragm acceptability: current use, consistency of use, and satisfaction with use. We conducted a telephone survey with 448 female members of a managed care organization, aged 18-49, who currently used contraception (including 140 diaphragm users, 187 pill users, and 121 male condom users). Use of a specific contraceptive was significantly associated with relationship length, condom-use negotiation self-efficacy, importance of covert use, perceived motivation of partner to prevent HIV/STIs, and perceived satisfaction of partner with current method. In addition, among diaphragm users, communication about HIV/STIs and perceived partner motivation to use a diaphragm were related to consistent use. These results suggest that acceptability of contraceptive methods among women is influenced by their perceptions of their male partner and relationship factors.
