Methodology
Cognitive interviews were conducted with 17 purposively selected adults and adolescents to assess understanding of the instructions-for-use. Video recordings of participants conducting unsupervised HIVST were analysed descriptively and scored using a pre-determined standardised checklist.

Summary of findings
Cognitive interviewing revealed that participants struggled to open the test kit easily. The most difficult instructions to understand were those related to the collection of oral fluid by swabbing the gums. Adolescents were more likely to swab accurately and to rely on both images and written instructions compared to adults. Understanding and interpreting images and particular terms (e.g. pouch, press firmly) was perceived as challenging. Video analysis showed that only 8/17 participants read the instructions-for-use before the test, despite explicit instructions to do so. There was a significant association (p< 0.05) between participants who read the instructions and their ability to correctly collect oral fluid sample. Only 4/17 participants were able to conduct all steps correctly. Women were 2.5 times more likely than men to perform all steps of the test correctly.
