Recruiting Women for a Study on Perceived Risk of Cancer: Influence of Survey Topic Salience and Early Versus Late Response
The Henry Ford Health System master patient list included women aged 30 years or older who had no ovarian cancer diagnosis (n = 55,887). Baseline survey reminder letters were sent approximately 1 week before commencing telephone calls. Of the 55,887 women, we established telephone contact with 49,600 women. We had no contact with 6,287 women. Among the 49,600 women contacted, the eligibility screener was administered successfully to 20,483 women; the rest of the contacts (n = 29,117) were nonresidential or nonhousehold, or the screener was not completed. Of the 20,483 women successfully screened, 16,720 women were eligible for the survey and assessed as high, elevated, or average risk; 3,763 women were ineligible for the survey. Of the 16,720 survey-eligible women, 3,307 were randomly selected for a full interview; 13,413 were not selected. We oversampled women at high and elevated risk. A computer-assisted telephone interview system randomly selected survey-eligible women for full interview in real time; we obtained informed consent from participants and conducted full interviews immediately after screening. All such activities generally occurred during 1 phone call. Of the 3,307 women selected for a full interview, 2,964 women began a full interview; 343 women refused to consent. Of the women who began a full interview, 2,524 completed a full interview, and 440 interviews were suspended.
