Approximately one-third of the healthy population suffer from sleep problems, but only a small proportion of those affected receive professional help. Therefore, there is an urgent need for easily accessible, affordable, and efficacious sleep interventions.
A randomized controlled study was conducted to investigate the efficacy of a low-threshold sleep intervention consisting of either (i) sleep data feedback plus sleep education or (ii) sleep data feedback alone in comparison with (iii) no intervention.
A total of 100 employees of the University of Salzburg (age: 39.51 ± 11.43 years, range: 22-62 years) were randomly assigned to one of the three groups. During the 2-week study period, objective sleep parameters were assessed actigraphy. In addition, an online questionnaire and a daily digital diary were used to record subjective sleep parameters, work-related factors, as well as mood and well-being. After 1 week, a personal appointment was conducted with participants of both experimental group 1 (EG1) and experimental group 2 (EG2). While the EG2 only received feedback about their sleep data from week 1, the EG1 additionally received a 45-min sleep education intervention containing sleep hygiene rules and recommendations regarding stimulus control. A waiting-list control group (CG) did not receive any feedback until the end of the study.
Results indicate positive effects on sleep and well-being following sleep monitoring over the course of 2 weeks and minimal intervention with a single in-person appointment including sleep data feedback. Improvements are seen in sleep quality, mood, vitality, and actigraphy-measured sleep efficiency (SE; EG1), as well as in well-being and sleep onset latency (SOL) in EG2. The inactive CG did not improve in any parameter.
Results suggest small and beneficial effects on sleep and well-being in people being continuously monitored and receiving (actigraphy-based) sleep feedback when paired with a single-time personal intervention.
约三分之一的健康人群存在睡眠问题，但只有一小部分患者能得到专业帮助。因此，迫切需要易于获取、价格合理且有效的睡眠干预措施。
开展一项随机对照研究，以调查低门槛睡眠干预措施的效果，该措施包括：（i）睡眠数据反馈加睡眠教育；（ii）仅睡眠数据反馈；并与（iii）不进行干预作比较。
萨尔茨堡大学的100名员工（年龄：39.51±11.43岁，范围：22 - 62岁）被随机分配到三组中的一组。在为期2周的研究期间，通过活动记录仪评估客观睡眠参数。此外，使用在线问卷和每日数字日记记录主观睡眠参数、工作相关因素以及情绪和幸福感。1周后，对实验组1（EG1）和实验组2（EG2）的参与者进行了个人约谈。EG2仅收到第1周睡眠数据的反馈，而EG1还额外接受了45分钟的睡眠教育干预，内容包括睡眠卫生规则和关于刺激控制的建议。等待名单对照组（CG）在研究结束前未收到任何反馈。
结果表明，经过2周的睡眠监测以及包括睡眠数据反馈的单次个人约谈的最小干预后，对睡眠和幸福感有积极影响。在睡眠质量、情绪、活力以及活动记录仪测量的睡眠效率（SE；EG1）方面有所改善，EG2在幸福感和入睡潜伏期（SOL）方面也有所改善。不活动的CG在任何参数上均未改善。
结果表明，当与单次个人干预相结合时，对持续监测并接收（基于活动记录仪的）睡眠反馈的人群的睡眠和幸福感有微小但有益的影响。
