Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to compare the implementation and effectiveness of group and self-help based cognitive behavioral treatment for insomnia (CBT-I) delivered by occupational health services (OHS) in a randomized and controlled design (RCT) among different types of shift workers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Because of irregular sleep-wake pattern shift work is a challenge in the screening and treatment of chronic insomnia. Earlier results has showed that CBT-I delivered by trained nurses of OHS may be effective treatment also among workers with irregular work hours. The aim of the present study is to compare the implementation and effectiveness of OHS delivered group and self-help based CBT-I in a RCT design among different types of shift work.

Participants (n=90-120) are shift workers with insomnia disorder that has lasted at least three months. The participants are randomized to a) group-based CBT-I (6 group sessions); or b) mainly computerized self-help CBT-I (an individual session before and after the intervention) delivered by a trained OHS nurse or psychologist; or c) control group given a sleep hygiene intervention (1 individual session). Outcomes are assessed using a sleep diary, questionnaires, actigraphy and cognitive performance tests. To study the effect of CBT-I program at molecular level, blood samples of participants will be collected at baseline and at the end of the program for genetic analyses. The measurements are conducted at five time points for a period of two years.

The investigators expect to find that both group and self-help based CBT-I among different types of shift workers are effective low-intensity treatments of chronic insomnia compared to control intervention.

Through the training of OHS or general medical practitioners and by computerised self-help interventions the investigators may have better chance to make CBT-I more accessible to a larger number of insomniacs also with different types of working hours. Additionally, it may be possible to decrease chronic insomnia and unfavourably consequences of insomnia to the health and performance capacity in shift workers.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cognitive Behavioral Group Therapy for Insomnia

Includes 6 group sessions (90 minutes each). The groups are led by trained psychologist or nurse of occupational health services. The manualized treatment is based on the general CBT-I model and includes components such as sleep hygiene, relaxation, stimulus control, sleep restriction and cognitive restructuring. In addition, participants receive information on how to schedule sleep, wake and light based on circadian principles while working differently timed shifts.

Group Type EXPERIMENTAL

Cognitive Behavioral Group Therapy for Insomnia

Intervention Type BEHAVIORAL

Cognitive Behavioral Self-help Therapy for Insomnia

Mainly computerized self-help intervention. Includes an individual session before and after the intervention (30 minutes each) led by trained psychologist or nurse of occupational health services. The self-help treatment is based on the general CBT-I model and includes components such as sleep hygiene, relaxation, stimulus control, sleep restriction and cognitive restructuring. In addition, participants receive information on how to schedule sleep, wake and light based on circadian principles while working differently timed shifts.

Sleep Hygiene Guidance

Includes one individual session (60 minutes) led by trained psychologist or nurse of occupational health services. The intervention is based on sleep hygiene guidance.
