Cognitive Behavioral Therapy for Insomnia Among Different Types of Shift

Status Active, not recruiting

Clinical Trial Summary

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.

Clinical Trial Description

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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
