Given the novelty of the research design, it is critical to obtain feedback from participants on their experiences with ring-based studies to help with the development of future trials.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>In 2021, we conducted 26 semi-structured interviews with adult participants of a COVID-19 ring-based post-exposure prophylaxis trial based in Canada. We applied a purposive sampling approach and electronically recruited participants who tested positive for COVID-19 (Index Cases) and either agreed or declined for the study team to contact their potentially exposed contacts. We also included individuals who participated in the trial after being potentially exposed to an Index Case (known as Ring Members), and those who declined to participate after potential exposure. The methodological design of semi-structured interviews allowed participants to share their opinions and experiences in the trial (e.g., elements they enjoyed and disliked regarding their participation in the study).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The majority of participants in our study were women (62%) and the average age was 37.3 years (SD\u2009=\u200913.2). Overall, participants reported being highly satisfied with partaking in the ring-based trial. Notably, no substantial complaints were voiced about the trial\u2019s design involving contact after exposure. The most common reason of satisfaction was the knowledge of potentially helping others by advancing knowledge for a greater cause (e.g., development of potential treatment to prevent SARS-CoV-2 infection). Other reasons were curiosity about participating in a trial, and an activity to fill free time during the pandemic. A central element of dislike was confusion about instructions with the trial (e.g., independent at home SARS-CoV-2 testing). Additionally, maintaining confidentiality was a crucial concern for participants, who sought assurance that their data would not be shared beyond the scope of the study.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Our results have the potential to inform future research, including clinical trials such as ring-based studies, by incorporating insights from participants\u2019 experiences into the development of study protocols. Despite some protocol-related challenges, participants expressed high satisfaction, driven by the desire to advance science and potentially aid others.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12874-024-02394-0","type":"journal-article","created":{"date-parts":[[2024,11,5]],"date-time":"2024-11-05T08:03:04Z","timestamp":1730793784000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Motivations for enrollment in a COVID-19 ring-based post-exposure prophylaxis trial: qualitative examination of participant experiences"],"prefix":"10.1186","volume":"24","author":[{"given":"Julien","family":"Brisson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca","family":"Balasa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Bowra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David C.","family":"Hill","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aarti S.","family":"Doshi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Darrell H.
