This article describes recruitment activities and costs from two independently conducted studies that used similar, systematic approaches to recruiting two subgroups of underscreened women, Black women and Mexican women. The studies varied in number of recruiters, venues of recruitment, and region of the country. The ratio of women approached to women who were underscreened was 4:1 for Black women and 10:1 for Mexican women. Hysterectomy was a predominant reason for ineligibility among Black women but not Mexican women. In both studies, personal networks were the most productive method of identifying women. Flyers and organized community venues were least productive. The cost incurred for identifying a woman who was eligible for a focus group was 145 dollars for Black women and 59 dollars for Mexican women. Those planning research or program activities that include recruiting underscreened women either to focus groups or health services could benefit from this information.
