| Acceptance and Commitment Training | Behavioral | During the ACT-based intervention, participants will get 4 training sessions in groups, once a week for an hour. Additionally, participants will be asked to implement behavioural exercises such as mindfulness and value-based exercises into their daily schedule. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in subjective exhaustion measured by the German Version of the Shirom-Melamed Burnout Measure | Overall mean score as well as three subscales of Shirom-Melamed Burnout Measure ( P = physical fatigue; E= emotional exhaustion; and C= cognitive weariness, each ranging from 1-7). Note: Higher scores indicate higher levels of exhaustion (overall as well as on each scale P, E and C) | approx. every two weeks, and at follow up (i.e., approx. 5 weeks after last training session) |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Subjective well-being as assessed by General Health Questionnaire (GHQ-12) | Sum over twelve items, higher scores indicate worse psychological well-being | approx. every two weeks, and at follow up (i.e., approx. 5 weeks after last training session) |
| Change in subjective well-being as assessed by the Patient Health Questionnaire (PHQ-D) |

| Sleep Hygiene and bright light in the morning | Behavioral | During the chronobiological intervention, participants will get 4 training sessions in groups, one hour per week. Additionally, they will use a daylight lamp at home, for 30 minutes per day after waking up. |
|
Sum over each of the subscales assessing somatic, depressive, anxiety and stress symptoms. The subscale assessing panic symptoms, alcohol abuse and intake of medication will be categorically evaluated. |
| approx. every 4 weeks |
| Change in quality of circadian rhythm | Actimetric devices are worn during 2 x 28 days continuously. These devices store the amount of activity in a resolution of 30 Hz 24/7. For data analyses, these activity data will be aggregated to three values (stability, variability and relative amplitude) per participant and training episode by non-parametric circadian rhythm analyses; higher values indicate higher stability, variability and amplitude | Actimetric devices are worn during 2 x 28 days continuously. The outcome of actimetric data are aggregated per person and training episode |
| Change in subjective and objective sleep quality: Pittsburgh Sleep Quality Index (PSQI) | Subjectively assessed by the Pittsburgh Sleep Quality Index (PSQI, higher scores indicate worse subjective sleep quality), by a single question about sleep quality (higher scores indicate worse quality) and by actimetric analyses | PSQI is collected approx. every four weeks and at follow up (i.e. approx 5 weeks after last training), the single question and actimetric data are measured daily |
| Change in Subjective sleepiness in the morning | Measured by Karolinska Sleepiness Scale (KSS), higher scores indicate higher sleepiness | KSS is measured daily |
| Change in daytime subjective sleepiness | Measured by Epworth Sleepiness Scale (ESS): higher scores indicate higher sleepiness | ESS approx every four weeks |
| Change in Chronotype | Measured by a short version of the Munich Chronotype Questionnaire, higher scores indicate a later chronotype | approx. every 4 weeks and at follow up (i.e., approx. 5 weeks after last training session) |
| Change in Burnout severity | Measured by Maslach Burnout Inventory using sumscores of the subscales emotional exhaustion, depersonalization and personal achievement. Higher scores indicate higher exhaustion, depersonalization and better personal achievement | every 4 weeks |
| Change in Absences | Numbers of days absent if available from the employer | Assessed daily |
| Change in Implementation of treatment | Questions about frequency implementation of treatment in daily life | approx. every two weeks, and at follow up (i.e., approx. 5 weeks after last training session) |
