To assess attitudes toward DNA collection in an epidemiological study, focus groups were assembled in September 2007 with mothers who had participated in a case-control study of birth defects. Each recruited mother previously had completed an interview and had received a mailed kit containing cytobrushes to collect buccal cells for DNA from herself, her infant, and her infant's father during the period July 2004 through July 2007. A total of 38 mothers attended six focus groups comprising: (1) non-Hispanic Black mothers of case infants who participated or (2) did not participate in DNA collection, (3) mothers of any race or ethnicity who had case infants of low birth weight who participated or (4) did not participate in DNA collection, and (5) non-Hispanic Black mothers of control infants who participated or (6) did not participate in DNA collection. Moderator-led discussions probed maternal attitudes toward providing specimens, factors that influenced decision making, and collection method preferences. Biologics participants reported that they provided DNA for altruistic reasons. Biologics nonparticipants voiced concerns about government involvement and how their DNA will be used. Information provided (or not provided) on DNA use, storage, and disposal influenced decision making. Biologics participants and nonparticipants reported that paternal skepticism was a barrier to participation. All mothers were asked to rank DNA collection methods in terms of preference (cytobrushes, saliva, mouthwash, newborn blood spots, and blood collection). Preferred methods were convenient and noninvasive. Better understanding attitudes toward DNA collection and preferred collection methods might allow more inclusive participation and benefit future studies. Published 2009 Wiley-Liss, Inc.(dagger)
