Written parental consent in school-based HIV/AIDS prevention research

Objectives. We examined the process of obtaining active, written parental consent for a school-based HIV/AIDS prevention project in a South African high school by investigating (1) parental consent form return rates, (2) parents, recall and knowledge of the research, and (3) the extent to which this consent procedure represented parents wishes about their child's involvement in the research. Methods. This cross-sectional descriptive study comprised interviews with parents of children in grades eight and nine in a poor, petiurban settlement in Cape Town, Results. Within 2 weeks, 94% of 258 parents responded to a letter requesting written consent and of those, 93% consented, but stibsequent interviews showed that 65% remembered seeing the consent form, At the end of (lie interview, 99% consented to their child's participation, Conclusions, These findings challenge many of the assumptions underlying active written parental consent, However, they should not be used to deny adolescents at high risk of HIV infection the opportunity to participate in prevention trials. Rather, researchers together with the communities in which the(! research is undertaken need to decide on appropriate informed consent stratergies.
