Patients with insomnia frequently report disturbing, or being disturbed by, their bedpartner. We aimed to (1) characterize how individuals with insomnia and their bedpartners influence each other's sleep and (2) identify characteristics predicting vulnerability to wake transmission. Fifty-two couples (aged 19-82 years), where one individual was diagnosed with insomnia, participated. Sleep/wake patterns were monitored via actigraphy and sleep diaries for seven nights. Minute-by-minute sleep and wake concordance (simultaneous sleep/wake epochs), number of wake transmissions received (awakenings immediately preceded by wakefulness in the bedpartner), percent wake transmissions received (percentage of total awakenings that were transmitted), and percent of bedpartner's wake minutes resistant to transmission (ability to sleep through bedpartner wakefulness) were calculated. Mixed-effects modeling assessed within-couple bedtime and chronotype differences as predictors of dyadic sleep. We described rates of sleep concordance (MPatient = 63.8%, MPartner = 65.6%), wake concordance (MPatient = 6.6%, MPartner = 6.6%), total transmissions received (MPatient = 5.5, MPartner = 6.9 per night), percent transmissions received (MPatient = 18.5%, MPartner = 23.4% of total awakenings), and percent minutes resistant (MPatient = 56.4%, MPartner = 58.6% of bedpartner's wake time). Partners received wake transmissions at 1.25 times the rate of patients. Percent transmissions received was increased in couples with concordant bedtimes and individuals with later chronotype than their bedpartner. Patterns of chronotype and bedtime order predicting percent minutes resistant to transmission differed across the length of the rest interval. Transmission provides a novel characterization of how bedpartners influence sleep and provide insight into mechanisms of insomnia generation and maintenance. Understanding modifiable risk factors may provide ways to personalize insomnia treatments.

失眠患者经常报告说，他们的伴侣会干扰他们的睡眠，或者他们自己会干扰伴侣的睡眠。我们旨在：(1)描述失眠患者及其伴侣如何相互影响彼此的睡眠；(2)确定易受唤醒传递影响的特征。52 对夫妇（年龄 19-82 岁），其中一人被诊断为失眠症，参与了研究。通过活动记录仪和睡眠日记监测了七晚的睡眠/觉醒模式。通过每分钟的睡眠和觉醒一致性（同时的睡眠/觉醒时段）、接收到的觉醒传递次数（伴侣觉醒前立即唤醒的觉醒）、接收到的觉醒传递百分比（传递的总觉醒次数的百分比）和伴侣觉醒分钟的抗传递百分比（能够通过伴侣的觉醒入睡）来计算。混合效应模型评估了夫妻之间的就寝时间和昼夜节律类型差异，作为对二元睡眠的预测因素。我们描述了睡眠一致性的比率（MPatient = 63.8%，MPartner = 65.6%）、觉醒一致性的比率（MPatient = 6.6%，MPartner = 6.6%）、接收到的总传递次数（MPatient = 5.5，MPartner = 每晚 6.9 次）、接收到的传递百分比（MPatient = 18.5%，MPartner = 23.4%的总觉醒次数）和分钟抗传递百分比（MPatient = 56.4%，MPartner = 58.6%的伴侣觉醒时间）。伴侣接收到的唤醒传递次数是患者的 1.25 倍。在与伴侣就寝时间一致且个体昼夜节律类型晚于伴侣的夫妇中，接收到的传递百分比增加。预测对伴侣觉醒时间的抗传递分钟百分比的昼夜节律类型和就寝时间顺序模式在整个休息间隔的长度上有所不同。传递提供了一种新颖的描述方式，说明伴侣如何影响睡眠，并深入了解失眠症产生和维持的机制。了解可改变的风险因素可能为个性化失眠症治疗提供途径。有效睡眠治疗研究（Project REST），ANZCTR 注册：ACTRN12616000586415。
