This article examines the beliefs about Depo-Provera held by three gro
ups of contraceptors utilizing urban family planning clinics in the Un
ited States (n=836). Patients choosing Depo-Provera, oral contraceptiv
es, and Norplant were asked about their beliefs regarding Depo-Provera
in the following four domains: effectiveness in preventing pregnancy,
convenience, side-effects, and risk to health; and also for their per
ceptions regarding the physical discomfort and cost associated with th
e method. Findings reveal that patients choosing the pill and Norplant
give Depo-Provera significantly lower ratings for both convenience an
d effectiveness than do Depo-Provera accepters. Given the documented e
ffectiveness of Depo-Provera, this is a potential cause for concern. M
oreover, Norplant and pill choosers are most likely to hold inaccurate
beliefs regarding both the cost of Depo-Provera, and certain side-eff
ects associated with its use. Although more than half of all patients
believe that Depo-Provera would cause menstrual changes and weight gai
n, it is noteworthy that the proportions are not higher, given their k
nown association with the method. Knowledge about the likelihood of th
ese side-effects is essential, particularly for those choosing Depo-Pr
overa. Implications for physicians, counselors, and other family plann
ing professionals are discussed.
