This study investigated the feasibility of recruiting and delivering a digital cognitive behavioural therapy for insomnia (dCBT\u2010I) in this group. In a parallel open\u2010label randomised\u2010controlled feasibility trial, participants were recruited and screened via the internet and assessed for MCI using videoconference methods. Eligible participants were randomised to dCBT\u2010I (Sleepio, 6 weekly sessions) or control (3 online modules of sleep health education) over a 12\u2010week period. Inclusion criteria included adults aged \u2265\u200950\u2009years, Insomnia Severity Index (ISI)\u2009&gt;\u200910, and clinical criteria of MCI on a neuropsychological battery. The primary outcomes were the proportion of participants who met screening and randomisation criteria, and their recruitment pathway (clinic vs. online). A secondary outcome was the effect size of the difference in ISI between groups at week 12. Recruitment occurred March\u2013August 2023 (dCBT\u2010I\u2009=\u200919; control\u2009=\u200921; 30 females; mean [SD] age\u2009=\u200959.7\u2009years [7.3]; ISI\u2009=\u200917.0 [3.7]). 37% of participants issued a pre\u2010screening number (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009246) were eligible to attend online screening. 47% of those issued a screening number (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200990) were eligible to be randomised (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200942), with 2 not proceeding (final\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200940). dCBT\u2010I improved 12\u2009weeks ISI compared to control (Cohen's\n                    <jats:italic>d<\/jats:italic>\n                    [95% CI] \u22121.6 [\u22122.4 to \u22120.8]). 79% of participants completed \u2265\u20094 sessions.
