Description

Despite the important role of testing as a measure against the COVID-19 pandemic, user perspectives on SARS-CoV-2 tests remain scarce, inhibiting an improvement of testing approaches and pandemic preparedness. Conducted amid the second pandemic wave (late 2020 – early 2021) during a multi-arm trial evaluating SARS-CoV-2 surveillance strategies in Baden-Württemberg, Germany, this qualitative sub-study aimed to gain a deeper understanding of how test users and rejectors perceived mail-in SARS-CoV-2 gargle tests. We conducted 67 semi-structured in-depth interviews via telephone or video call. Interviews were audio-recorded, transcribed verbatim and analyzed inductively using thematic analysis. Respondents generally described gargle sampling as simple and comfortable. However, individual perceptions of the testing method and its feasibility varied widely. Self-sampling was appreciated for lowering infection risks during testing but also considered more complex. Gargle-sampling increased participants’ self-efficacy. Communication and trust decisively influenced the intervention’s acceptability. User-driven insights on how to streamline testing include: consider communication, first impressions of tests and information as key for successful mail-in testing; pay attention to the role of mutual trust between those taking and administering tests; implement gargle self-sampling as a pleasant alternative to swab testing; offer multiple test methods to increase test up-take.
