ABSTRACT
Procedures Eligible women from the HMO were identified by
computer and sent an introductory letter signed by the medical director of the HMO. This letter was followed
230 by a telephone call from a research assistant, who further described the study and asked each woman if she would be willing to participate. If agreement was obtained, the participant was sent an informed consent statement and a questionnaire that included the scales
235 for susceptibility, benefits, and barriers. Upon return of the completed questionnaire, women were assigned to a control or intervention group. Following intervention, a second data collection occurred, via a mailed questionnaire. In this report, the second data set was used
240 for test-retest calculations. Because the intervention may have changed actual beliefs, only control group women were used for test-retest computations.
