Despite their vulnerability, adolescents are often excluded from health research due to ethical concerns about research with minors, especially in low-income regions like Sub-Saharan Africa. We enrolled adolescent girls aged 15–17 years and caregivers of girls of the same age. Using a 25-question Comprehension Score Sheet, we applied a quantitative approach to compare the comprehension of informed consent of 33 adolescent girls and 41 caregivers of adolescent girls aged 15–17 years. The assessments were audio-recorded and reviewed for quality check. The (...) results showed that adolescent girls were significantly better than caregivers in comprehending informed consent information overall and specifically on study procedures, voluntarism and study purpose. This suggests that adolescents can understand informed consent information at the same level as or better than caregivers who are entrusted with providing permission for adolescents to participate in research.
