• Description:
  Study Objectives:
  
  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.
  
  Design:
  
  Cluster-randomized trial.
  
  Setting:
  
  A global Information Technology (IT) firm.
  
  Participants:
  
  Knowledge workers employed in the US at the participating IT firm.
  
  Interventions:
  
  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.
  
  Measurements and Results:
  
  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.
  
  Conclusions:
  
  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.
