Views on data use, confidentiality and consent in a predictive screening involving children.

Data from the 5-6 year control questionnaire of the ABIS study, a Swedish prospective screening of children for Type 1 diabetes, indicates a genuine trust in the researchers--very few participating families expressed concern about their participation. Nevertheless, a majority do not want their research data to be used beyond the agreement of the original consent. They want to be asked for renewed consent in such cases. A vast majority also want potential high-risk information about their child to be communicated to them. Most participating families want this regardless of whether any preventive treatment is available. Although potential benefits for their child is a motivation for participation for a majority of the respondents, they also claim to be motivated by altruistic reasons. These results are compared to results from two similar studies in the UK.
