Completion rates and uptake for participant selected cognitive behavioural therapy treatment modality.

	Completion rate (%) proportion (n) [95% CI]
Digital CBT only	47% (7/15) [21,73]
Face-to-face CBT only	26% (7/27) [11,46]
Digital CBT + face-to-face CBT	71% (5/7) [29,96]
SRT only	100% (6/6) [54,100]
SRT + face-to-face CBT	75% (3/4)
SRT + digital CBT	0% (0/1)

Note: From 96 participants, 60 started at least one form of therapy for insomnia, 28 completed therapy (defined as 5 face-to-face CBT sessions, 6 sessions of digital CBT or 5 weeks of SRT), and 36 did not start therapy at our clinic. Completion rates are expressed as a percentage of the number of participants who completed against those who started CBT by treatment modality with 95% confidence intervals. Confidence intervals and are not calculated when the numerator is 3 or fewer because the rate is not statistically distinguishable from zero. CBT: cognitive behaviour therapy; I-NSD: Insomnia with normal sleep duration; I-SSD: Insomnia with short sleep duration; SRT: sleep restriction therapy.
