0337 COGNITIVE BEHAVIORAL THERAPY FOR MENOPAUSAL INSOMNIA IN MIDLIFE WOMEN WITH INSOMNIA AND NOCTURNAL HOT FLASHES

Abstract Introduction: Between 30–60% of peri- and postmenopausal women in the United States suffer from insomnia symptoms. Menopausal women with nocturnal hot flashes often report worse sleep quality and are more likely to meet criteria for insomnia disorder than those without nocturnal hot flashes. Thus, tailoring interventions to treat both insomnia and hot flashes may improve sleep and quality of life of millions of women. This pilot study examined the efficacy of cognitive behavioral therapy for insomnia and hot flashes among midlife women. Methods: Forty women (mean age= 55 ± 6.2) self-described as peri- or post-menopausal who reported ≥ 1 nocturnal hot flash/night and met diagnostic criteria for insomnia disorder were randomized to cognitive behavioral therapy for menopausal insomnia (CBTMI) or menopause education control (MEC). Treatment included four individual 50-minute sessions over eight weeks, delivered by social workers or psychologists in gynecology clinics. Pre and posttreatment measures included: Insomnia Severity Index (ISI), Center for Epidemiologic Studies Depression Scale (CES-D), and Self-Efficacy Scale for Sleep (SES). Results: Mixed models revealed a significant time x treatment arm interaction for insomnia severity (p=.003), depression severity (p=.019), and sleep self-efficacy (p=.021), with significant main effect for time for all domains (p’s
