This study evaluated the feasibility and efficacy of a scalable cognitive behavioural therapy (CBT) sleep intervention tailored for these periods.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0033291721001860_sec_a2\" sec-type=\"methods\">\n\t    <jats:title>Methods<\/jats:title>\n\t    <jats:p>This is a two-arm, parallel-group, single-blind, superiority randomised controlled trial. Nulliparous females without severe medical\/psychiatric conditions were randomised 1:1 to CBT or attention- and time-matched control. All participants received a 1 h telephone session and automated multimedia emails from the third trimester until 6 months postpartum. Outcomes were assessed with validated instruments at gestation weeks 30 (baseline) and 35 (pregnancy endpoint), and postpartum months 1.5, 3, 6 (postpartum endpoint), 12 and 24.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0033291721001860_sec_a3\" sec-type=\"results\">\n\t    <jats:title>Results<\/jats:title>\n\t    <jats:p>In total, 163 eligible participants (age M \u00b1 <jats:sc>s.d.<\/jats:sc> = 33.35 \u00b1 3.42) were randomised. The CBT intervention was well accepted, with no reported adverse effect. Intention-to-treat analyses showed that compared to control, receiving CBT was associated with lower insomnia severity and sleep disturbance (two primary outcomes), and lower sleep-related impairment at the pregnancy endpoint (<jats:italic>p<\/jats:italic> values \u2a7d 0.001), as well as at 24 months postpartum (<jats:italic>p<\/jats:italic> ranges 0.012\u20130.052). Group differences across the first postpartum year were non-significant. Participants with elevated insomnia symptoms at baseline benefitted substantially more from CBT (<jats:italic>v.<\/jats:italic> control), including having significantly lower insomnia symptoms throughout the first postpartum year. Group differences in symptoms of depression or anxiety were non-significant.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0033291721001860_sec_a4\" sec-type=\"conclusions\">\n\t    <jats:title>Conclusions<\/jats:title>\n\t    <jats:p>A scalable CBT sleep intervention is efficacious in buffering against sleep disturbance during pregnancy and benefitted sleep at 2-year postpartum, especially for individuals with insomnia symptoms during pregnancy.
