简要总结
This randomised controlled trial assessed the efficacy of four mental imagery techniques for improving sleep and its related behaviour: (1) imagery focused on reducing arousal levels; (2) imagery incorporating implementation intentions (a strategy designed to link specified behaviour with the anticipated context) for sleep-related behaviour; (3) a combination of imagery using arousal reduction and implementation intention strategies; or (4) a condition where participants were asked to imagine their typical post work activities.
详细描述
Sleep deprivation is a significant health issue in the modern workplace. We conducted a randomized controlled trial to test the efficacy of techniques involving mental imagery promoting relaxation (arousal reduction; AR) and simulation of the appropriate sleep behavior in the likely environments (implementation intentions; II) in a population of daytime employees

结局指标
主要结局
Sleep Quality
时间窗: Baseline and at 3 weeks. Data will also be presented for every day for the duration of the 3 week period so change can be reported.
Assessed using the Pittsburgh Sleep Quality Index (PSQI; Buysse et al, 1989).The PSQI includes 19 items that assess sleep quality, hours of sleep, sleep onset length, sleep efficiency, sleep disturbances, use of medication and daytime. Item ratings are recoded and combined to form seven component scores. These scores are then summed into a global score ranging from 0(no difficulty) to 21(severe difficulties in all areas). Daily sleep quality was assessed with five PSQI items.
