Supplementary quotes to support the qualitative themes in the study

Themes	Quotes to support them
Confidence in the youth‐friendly environment	‘This is good hospitality offered here at CHIEDZA, different from what is done in clinics and hospitals by the nurses who don't care about patients but focus on doing what makes them get paid at the end of the month…’ (FGD2, 17‐year‐old female, provider tested)
Barriers to HIVST
Lack of confidence in their expertise in using the oral test‐kit	Most participants ‘had never heard about’ self‐testing (paired IDI1, 17‐year‐old female, provider tested) ‘Personally, for me I had never heard about it. When I came to Chiedza, that's when I knew that there is an HIV test kit which is called self‐testing and I enjoyed the experience…., “the person [provider] fully explained everything such that I understood what they were saying”’ (paired IDI1, 17‐year‐old female, provider tested).
Fear of finding out test results alone	Many young people discussed fears of ‘the results coming out as HIV positive’ leading to ‘mental problems’ and even ‘you might think of killing yourself’ (FGD2 and FDG4, both 16‐year‐old females, provider tested). ‘Proper support system to comfort me when I needed the support’ at home was the key aspect (paired interview 2, female, 24 years old, provider tested)
