The goal of this clinical trial is to evaluate the usefulness of cognitive behavioural therapy for insomnia (CBT-I) tailored to shift workers in the social and health care sector. The study will also learn about the shift workers' experiences of the acceptability and feasibility of CBT-I and investigate which features of shift work and individual characteristics promote or interfere with the effectiveness of the tailored CBT-I.
The main question the study aims to answer is:
• Does CBT-I tailored to shift workers in the social and health care sector improve perceived insomnia severity, insomnia symptoms, mental health and quality of life?
Researchers will compare CBT-I to a control intervention (short sleep hygiene counselling) to see if CBT-I works to treat insomnia in shift workers.
Participants will:
Disturbed sleep and insomnia are common among shift workers, and disturbed sleep is considered a key factor in other health risks associated with shift work. However, there are no established treatment practices for treating insomnia in shift workers. This study aims to evaluate the effectiveness of Cognitive-Behavioural Therapy for Insomnia (CBT-I) tailored for social and health care sector shift workers whose work includes night shifts. Furthermore, the study will assess the shift workers' experiences of the acceptability and feasibility of CBT-I from their perspective. The study will also examine which features of shift work and employee characteristics promote or interfere with the effectiveness of the tailored CBT-I.
The study is a randomised controlled trial. Participants will be shift workers in the social and health care sector who work in three or two shifts, including night shifts, and have significant insomnia symptoms. Participants will be recruited through occupational health services (OHS) and social media posts. The FIOH study group will carry out the measurements of the participants. Participants will complete the baseline measures (sleep diary, actigraphy and questionnaires) and then will be randomly assigned to receive the research intervention (CBT-I tailored to the shift work context; six individual sessions) or the control intervention (sleep hygiene counselling; one individual session). The interventions will be delivered by the nurses of the participants´ OHS and the FIOH. Participants will complete the follow-up measures after the end of treatment (12 weeks after the first session) and at 6 months after the end of treatment.
The results of the study can be utilised in OHS to guide and treat shift workers with insomnia as part of supporting their work ability.

| Cognitive behavioral therapy for insomnia | Behavioral | Cognitive-Behavioural Therapy for Insomnia (CBT-I) includes behavioral methods, cognitive methods, and sleep hygiene counselling. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in mean of Insomnia Severity Index at the end of treatment (12 weeks after the first session) and at 6 months after the end of treatment. | Insomnia Severity Index (ISI) contains seven items about insomnia during the last month [item scale 0 (not at all) -4 (very severe)]. The sum of the scores serves as the ISI score. | From baseline to the end of treatment (12 weeks after the first session) and to the 6 months after the end of treatment. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in means of insomnia symptoms assessed by sleep diary at the end of treatment (12 weeks after the first session) and at 6 months after the end of treatment. | Insomnia symptoms are assessed by sleep diary. It is completed using a mobile phone app (Experience Sampling Platform - movisensXS - movisens GmbH). The sleep diary contains questions about the timing of the sleep period, sleep onset latency, wake after sleep onset, number of awakenings after sleep onset, sleep quality, time spent in bed, restedness after sleep, use of sleep-promoting medication, working times, recovery from work, naps and their timing. Total sleep time and sleep efficiency are calculated from the responses. The averages will serve as the outcomes. Participants will keep the sleep diary for 1-2 weeks at each measurement period. |
| Measure | Description | Time Frame |
|---|---|---|
| Implementation experiences of the interventions | Participants' experiences of the implementation of the interventions are assessed using the Acceptability of Intervention Measure, the Intervention Appropriateness Measure, and the Feasibility of Intervention Measure [each with four items and a scale 1 (completely disagree) - 5 (completely agree)]. The average of each measure serves as a acceptability, appropriateness and feasibility measure of implementation. |
