Acceptable Risks in Pediatric Research: Views of the US Public

Critics argue that it is unethical to expose children to research risks for the benefit of others, whereas many regulations permit "net-risk" pediatric research but only when the risks are minimal. In the present survey, we assessed whether the US public agrees with these views and whether the US public's views regarding the acceptability of net-risk pediatric research are influenced by its social value.

A 15-minute survey of a nationally representative sample of US adults. Participants were randomly assigned to 1 of 4 hypothetical scenarios involving procedures that pose increasing levels of risk. To assess whether respondents' views on the acceptability of the risks is influenced by the social value of the research, in each of the 4 scenarios we described the respective procedure being used in 3 studies with increasing levels of social value.

A total 1658 of the 2508 individuals who were sent the survey link participated (response rate = 66.1%). Approximately 91% approved of a research blood draw in minors, and ∼69% approved of a research bone marrow biopsy. The proportion who indicated that the respective procedure was acceptable increased as the study's social value increased. This effect was significantly stronger for studies which pose greater risks compared with studies with lower risks (P < .001).

The vast majority of the US public supports net-risk pediatric research that poses minimal risk, and a majority supports net-risk pediatric research that poses somewhat greater risks, provided it has high social value. These findings offer important information for assessing when it is acceptable to conduct net-risk pediatric research.
