AWAKE Check: Assessing insomnia and sleep apnoea risk in UK adults (protocol and preregistration archive)

This record contains the preregistration protocol for the AWAKE Check study, a UK-based population screening initiative assessing risk of insomnia and obstructive sleep apnoea (OSA) in adults. AWAKE Check uses validated instruments (Insomnia Severity Index [ISI] and STOP-Bang) to identify insomnia symptoms, OSA risk, and potential comorbid insomnia and sleep apnoea (COMISA). Objectives Estimate the proportion of UK adults screening positive for insomnia (ISI ≥ 15), OSA risk (STOP-Bang ≥ 3), and COMISA. Explore subgroup variation by age and sex. Examine feasibility of online engagement and recruitment via social/professional networks. Ethics and data handling The survey is anonymous; no participant contact details are retained in the research dataset. Optional email addresses may be provided only for prize draw administration and/or to return participants their individual scores. These are stored separately, not linked to survey responses, and permanently deleted after prize administration. Funding This project received no external funding. It is conducted as part of Adrian Karl Zacher’s doctoral research at Vrije Universiteit Brussel (VUB).
