Brief Summary in Lay Language

The recovery training is for employees, who have sleep problems and problems with mentally detaching from work. After stress at work we mentally and physically seek for recovery. Many employees experience rather loose boundaries between work and private life. Due to Internet and smartphones, many employees are nonstop available for work and private spaces for recovery are experienced less. Some stress factors are then seen as inevitable. Esspecially then, phases of successful recovery are very important to prevent chronic stress reactions. Chronic stress reactions are developed, when it is repeatedly not possible to establish recovery. Recovery means: a)mental detachment from work, because worrying and rumination about problems at work can lead to the same strain as work itself. b) recovery activities, that are important to promote mental detachment (to "switch off") and c) restaurative sleep. This is the most important element of recovery. Occupational stress and esspecially corresponding rumination and worrying lead to increased strain and tension, which is one cause for sleep disorders. 10 % of the population suffer from problems falling asleep, sleeping through or waking to early in the morning.
Aim and hypotheses: the online training which is to evaluate was already evaluated in two randomized controlled trials successfully. the samples consisted of teachers. the primary aim of this study is to make conclusions on the generalizability of the previous results on employees in general. Also, we aim to investigate a previously not tested format of the training. while in study 1, an online coach gave feedback after each lesson and in study 2, participants went through the training on their own as pure self-help, now in this study, the format tested is "feedback on demand".

Brief Summary in Scientific Language

Insomnia and work-related stress often co-occur. Both are associated with personal distress and diminished general functioning, as well as substantial socio-economic costs. Internet-based CBT-I interventions (ICBT-I) could potentially reduce the given supply gap and are proven to be effective. There is less known about the efficacy of ICBT-I in populations affected by work-related stress. The present training specifically addresses those employees who have problems with seperating work and private life, e.g. because of anticipated expectation of 24/7 availability. Given a complicated seperation between work and private life, detachment from work and recovery in general becomes more difficult.
In a two-arm randomized controlled trial (N = 128), the effects of a guided ICBT-I training ("GET.ON Recovery") will be compared to a waitlist-control condition, pre-treatment, post-treatment and at 6-months follow-up.German teachers with clinical significant insomnia complaints and work-home interference are included. Apart from classic CBT-I elements (e.g. sleep hygiene, sleep restriction) GET.ON Recovery accentuates the promotion of recreational activities and cognitive detachment. The primary outcome is insomnia severity.

Interventions/Observational Groups

  •   • Arm 1: six week online training with consisting of 6 modules which each take about 1 hour. Format: feedback on demand. Feedback on single online exercises is only given when participants asks for it. Nevertheless, during the training, the primary study investigator is available for technical questions. Half of the total sample (N=128, n = 64) is randomised in Arm 1. this group gets "GET.ON Recovery", a sleep training based on Cognitive Behavioral Therapy, that is specifically designed for employees with occupational strain. This training aims to reduce insomnia severity, measured by the Insomnia Severity Index (ISI). Insomnia Severity as well as secondary outcomes like rumination or depressive symptoms will be measured pre-treatment, post-treatment (8 weeks) and at 6-months follow-up.
  •   • Arm 2: waitlist-control-group (receives online-training without feedback on demand following the 6-months follow-up). Before Arm 1 gets access to the online training (GET.ON Recovery), both groups, Arm 1 and Arm 2,fill in the Baseline questionnaires (online). After Arm 1 worked through the online training (8 weeks), Arm 1 and Arm 2 fill in the post-questionnaires (online). At 6-months follow-up, again online questionnaires are to be filled in. The questionnaires assess insomnia severity, rumination, depressive symptoms, etc. After the last assessment, 6 months after randomization, Arm 2 receives access to GET.ON Recovery. During the traning, Arm 2 does not receive regular e-mail support, but the primary study investigator is available when a participant has a question regarding technical problems.
