Background Data sharing presents several challenges to the informed consent process. Unique challenges emerge when sharing pediatric or pregnancy-related data. Here, parent preferences for sharing non-biological data are examined. Methods Groups and individual interviews were conducted with participants from two provincial, longitudinal pregnancy cohorts. Qualitative content analysis was applied to transcripts of semi-structured interviews. Results Participants were supportive of a broad, one-time consent model or a tiered consent model. These preferences were grounded in the perceived obligations for reciprocity and accuracy. (...) Parents want reciprocity among participants, repositories and researchers regarding respect and trust. Furthermore, parents’ worry about the interrelationships between the validity of the consent processes and secondary data use. Conclusions Though parent participants agree that their research data should be made available for secondary use, they believe their consent is still required. Given their understanding that obtaining and informed consent can be challenging in the case of secondary use, parents agreed that a broad, one-time consent model was acceptable, reducing the logistical burden while maintaining respect for their contribution. This broad model also maintained participant trust in the research and secondary use of their data. The broad, one-time model also reflected parents’ perspectives surrounding child involvement in the consent process. The majority of parents felt decision made during childhood were the parents responsibility and should remain in parental purview until the child reaches the age of majority. (shrink)
