A systematic review of trials comparing single-component SRT to waitlist control or sleep hygiene advice found medium-to- large effects on sleep continuity measures.22 Moreover, recent trials suggest SRT may be as effective as multicomponent CBT.23 24 One primary care trial compared brief SRT (delivered by one GP) with sleep hygiene advice.25 The participants were highly selected so that they were free from comorbidity or medication use. SRT significantly reduced insomnia severity at 6 months (Cohen’s d=0.54). While this was an important first study, a pragmatic trial in primary care testing a scalable model of treatment delivery is clearly required.
