0470 A Randomized Controlled Trial of Digital Cognitive Behavioral Therapy for Insomnia in Pregnant Women

Abstract

Introduction: . Over half of pregnant women experience clinical insomnia, which is linked to perinatal depression and cognitiveemotional dysregulation. Despite high rates of prenatal insomnia and known maternal consequences, efficacious insomnia treatment options for this population are woefully scant. Early evidence from randomized controlled trials (RCTs) support the efficacy of face‐to‐face cognitive‐behavioral therapy for insomnia (CBTI) for prenatal insomnia. Yet, as many patients are unable to access this specialist‐driven care, a critical need exists to increase its accessibility. This RCT examined the efficacy digital CBTI via mobile health app in pregnant women with insomnia. Methods: Single‐site RCT. Ninety‐one pregnant women (29.03±4.16 years) nearing/entering the third trimester who screened positive for clinical insomnia on the Insomnia Severity Index (ISI) were randomized to digital CBTI or digital sleep education control. Blinded assessments were performed before treatment, after treatment (during pregnancy), and 6 weeks after childbirth. The ISI, Pittsburgh Sleep Quality Index (PSQI), Edinburgh Postnatal Depression Scale (EPDS), and Pre‐Sleep Arousal Scale's Cognitive factor (PSAS‐C) served as study outcomes. Results: From pre to posttreatment, CBTI patients reported reductions in ISI (‐4.91 points, p
