Multidimensional Sleep Health Intervention for Couples

Plain-language summary

The goal of this pilot dyadic study is to adapt a multidimensional sleep health (MDSH) intervention, previously disseminated at the individual level, for relationship partners, determine whether it improves sleep health and aspects of cardiometabolic health, and understand the role of dyadic dynamics in intervention effects. Can a dyadic MDSH intervention improve sleep health and blood pressure (primary outcomes) in relationship partners? Can a dyadic MDSH intervention improve anthropometric markers of adiposity, psychosocial indicators, stress, dyadic adjustment and coping, self-rated health (secondary outcomes) in relationship partners? As this is a single-arm study, there is no control group. All relationship partners will complete a three-tier screening process, attend two in-person visits to receive intervention materials, have blood pressure measured and sleep data collected using in-office and out-of-office monitors, participate in weekly check-in phone calls with research staff over the 8 weeks to support adherence and complete a voluntary follow-up phone call at 16 weeks to provide additional sleep health information. The multidimensional sleep health promotion intervention is based on evidence-based sleep hygiene education and established behavior change techniques and includes: report-back of sleep health profiles, S.M.A.R.T (specific, measurable, attainable, realistic, and timely) goal-setting and establishing a sleep health plan with a fixed sleep schedule, sleep health coaching and dyadic action planning, self-monitoring, virtual sleep hygiene education, motivational feedback, and addressing light and noise in the sleep environment. Mixed methods will be used to understand implementation metrics, processes, and outcomes to establish the successful completion and future expansion of the intervention within this context.
