Abstract
The factors associated with choice of birth control pills or a diaphragm were examined, using concepts derived from the Health Belief Model (Rosenstock, 1974). Women who visited a suburban family planning clinic completed a self‐administered questionnaire (N— 632) indicating their contraceptive choice, attitudes about different methods of contraception, and perceived threat of pregnancy. Using discriminant function analysis, pill users were distinguished from diaphragm users by (a) their reported perception of greater support from others for using the pill, (b) their reported belief the diaphragm was more inconvenient to use and the pill more convenient, (c) expressing less concern about the pill's side effects, (d) believing they were more protected from pregnancy when using the pill and more susceptible when not using it, and (e) knowing less about contraception in general. They also were younger and more likely to be involved in a committed sexual relationship. Results are consistent with the Health Belief Model and also support the inclusion of a subjective‐norm factor into the model.
