工作、家庭和健康网络研究验证了一个假设，即旨在增加家庭支持监督和员工对工作时间的控制的工作场所干预可以改善睡眠数量和质量的活动测量。随机对照试验。一家全球性的信息技术（IT）公司。在参与的IT公司在美国雇用的知识工作者。随机选择的经理和员工参加了为期三个月的社会和组织变革过程，旨在减少工作与家庭的冲突。干预措施包括互动式会议，促进讨论，角色扮演和游戏。管理人员完成了家庭支助监督方面的培训。从基线和12个月的为期一周的体动记录中收集总睡眠时间（睡眠持续时间）和入睡后觉醒（WASO;睡眠质量）的主要结果。次要结果包括自我报告的睡眠不足和失眠症状。n=701人（93%保留）完成了为期10个月的访谈，其中595人（85%）完成了腕动记录。将分析限制在活动记录有效天数≥ 3天的受试者中，获得了用于干预有效性分析的最终样本n=474。活动描记法测量的睡眠持续时间在干预员工中比对照员工多8分钟/天（p<0.05）。干预员工的睡眠不足也有所减少（p=.002）。WASO和失眠症状组间无差异。路径模型表明，减少工作-家庭冲突部分介导的睡眠充足性的改善。工作场所的干预并没有公开解决睡眠问题，但干预员工每周多睡一个小时，睡眠充足。干预措施应解决睡眠不足的环境和心理社会原因，包括工作场所因素。
The Work, Family, and Health Network Study tested the hypothesis that a workplace intervention designed to increase family-supportive supervision and employee control over work time improves actigraphic measures of sleep quantity and quality. Cluster-randomized trial. A global Information Technology (IT) firm. Knowledge workers employed in the US at the participating IT firm. Randomly selected clusters of managers and employees participated in a three-month, social and organizational change process intended to reduce work-family conflict. The intervention included interactive sessions with facilitated discussions, role-playing, and games. Managers completed training in family-supportive supervision. Primary outcomes of total sleep time (sleep duration) and wake after sleep onset (WASO; sleep quality) were collected from week-long actigraphy recordings at baseline and 12 months. Secondary outcomes included self-reported sleep insufficiency and insomnia symptoms. Twelve-month interviews were completed by n=701 (93% retention), of whom 595 (85%) completed actigraphy. Restricting analyses to participants with ≥ 3 valid days of actigraphy yielded a final sample of n=474 for intervention effectiveness analyses. Actigraphy-measured sleep duration was 8 minutes/day greater among intervention employees relative to control employees (p<.05). Sleep insufficiency was also reduced among intervention employees (p=.002). WASO and insomnia symptoms were not different between groups. Path models indicated reduced work-family conflict partially mediated the improvement in sleep sufficiency. The workplace intervention did not overtly address sleep, yet intervention employees’ slept an hour/week more and reported greater sleep sufficiency. Interventions should address environmental and psychosocial causes of sleep deficiency, including workplace factors.
