Studies suggest that recovery from work and the ability to recreate one`s resources is a key factor relevant for maintaining and restoring physical and mental health. Especially, restorative sleep is of major importance for successful recovery from work-stress. Insomnia is a risk factor for adverse health such as subsequent depression or cardiovascular events. Insomnia complaints often result from cognitive arousal and deficient cognitive detachment from work. Insomnia is also associated with a lack of positive recreational activities that facilitate cognitive detachment and reduce work-related rumination.
Therefore, GET.ON Recreation was developed and aimed to target (a) sleep, (b) cognitive detachment and (c) recreational activities. GET.ON Recreation is an online training combining techniques from cognitive behavioral therapy for insomnia, behavioral activation and techniques to reduce rumination and to foster cognitive detachment from work-related problems. The aim of the present study was to evaluate the efficacy of this guided online training for employees affected by insomnia.

Methods: In a two-arm randomized controlled trial (N=128), the effects of a guided online training were compared to a waitlist-control condition. Teachers with high insomnia complaints (Insomnia Severity Index ISI≥15) and work-related rumination (Irritation Scale, subscale Cognitive Irritation ≥15) were included in the study. The primary outcome measure was insomnia severity. Additionally, an economic evaluation was conducted.

Results: Preliminary results based on 85% of the participants and per protocol analyses demonstrated to training to be effective. The Intervention group improved in their sleep quality from pre- to post-training by d=2.0. At post-training the ISI-scores of the trainings group were substantially better than the respective scores in the control-group (d=1.3). Based on the Jacobson and Truax method to determine reliable change the Number Needed to Treat were found to be NNT=2. Furthermore a strong “side effect” on the reduction of depression was observed (d=0.8). Likewise, the training group achieved a reduction in work-related rumination (d=0.7).

Discussion: To the best of our knowledge, this is the first study evaluating an online training targeting insomnia complaints and work-related rumination. Preliminary results demonstrated the efficacy of the training, although the effects might decrease when Intention-to-Treat analysis will be conducted using the whole sample. The 6-month follow up will be completed in April 2014 and data will be presented. Finally it is suggested that the trainings should be investigated in other occupational groups and other training formats such as pure self-help.
