  "abstract": "Introduction Poor sleep among adolescents poses significant risks to their health and wellbeing. A key contributor to delayed bedtimes and disrupted sleep is night-time use of interactive electronic devices (IEDs), including for social media. This study aimed to assess the feasibility of CLOCK OFF, a school-based intervention combining teacher-led lessons and peer-nominated students trained as Peer Supporters (PS) to promote healthy sleep habits and reduce IED use.Methods The intervention was implemented with S1 students in four Scottish schools during 2024. Phase 1 (two schools) ran from April to June, followed by intervention refinements and Phase 2 (two schools) from August to November. Sixty Peer Supporters and X teachers were trained by a sleep charity. Semi-structured interviews and focus groups were conducted to assess perspectives from Peer Supporters (n = 18), non-Peer Supporters (n = 9), teachers (n = 8), parents (n = 8), and trainers (n = 3). Data underwent thematic analysis, with 50% independently double-coded.Results Key strengths identified included the peer nomination process (representative, fair), engaging peer training and teacher-led lessons (useful and comprehensive, engaging materials and activities), and benefits of the PS role (improved confidence, expanded social networks, and reports of reduced IED use). Challenges included teacher time constraints (study set up, training, lesson delivery), perceived role of PS (sharing peer messages, gap in digital strategies, limited awareness of PS), engagement (fidelity of nomination process, training materials, parental involvement), research challenges (school coordination, obtaining consent).Conclusions Feasibility testing addressed uncertainties and informed adaptations for future randomized controlled trials. Further refinements will consider the duration of teacher training, dose of PS training, session content and materials, inclusion of digital strategies, and parental engagement. These modifications aim to enhance the impact and scalability of CLOCK OFF.",
