The aim of the present project is to combine "Acceptance and Commitment Therapy" and "sleep hygiene + light-therapy (so-called chronotherapy)" serially in a sample of employees to reduce levels of subjective exhaustion.

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.
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.

RECRUITINGChange 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)
Time frame: 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 General Health Questionnaire (GHQ-12)
Sum over twelve items, higher scores indicate worse psychological well-being
Time frame: 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)
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.
Time frame: 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
Time frame: 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
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Time frame: 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
Time frame: KSS is measured daily
Change in daytime subjective sleepiness
Measured by Epworth Sleepiness Scale (ESS): higher scores indicate higher sleepiness
Time frame: ESS approx every four weeks
Change in Chronotype
Measured by a short version of the Munich Chronotype Questionnaire, higher scores indicate a later chronotype
Time frame: 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
Time frame: every 4 weeks
Change in Absences
Numbers of days absent if available from the employer
Time frame: Assessed daily
Change in Implementation of treatment
Questions about frequency implementation of treatment in daily life
Time frame: approx. every two weeks, and at follow up (i.e., approx. 5 weeks after last training session)
