Parental waivers to enable adolescent participation in certain forms of health research: lessons from a South African case study

The South African legal framework requires mandatory parental/legal guardian consent for all research with children. Ethics guidelines provide some reprieve by allowing RECs to grant waivers of parental or guardianship consent in certain defined circumstances. In the first instance, consent may be provided by a proxy when parents or guardians are unavailable, for example with orphaned children. In the second instance, guidelines permit adolescent self-consent when the nature of the study justifies this approach, for example, research on sensitive issues like sexual behaviour or substance use. South African guidelines set several conditions that must be met for waivers to be granted. These norms overlap with those in international guidelines. However, the ethical norms, especially related to self-consent are sometimes vague. This article critically evaluates the consent norms in the national ethics guidelines and makes recommendations for reform to ethics guidelines in a way that recognises the value of child participation in research, their evolving decision-making capacity and their best interests.
