What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests two methods to help night shift nurses with sleep problems. One approach uses Cognitive Behavioral Therapy for Insomnia (CBTI), which changes thoughts and behaviors related to sleep. The other method is Multicomponent Relaxation Therapy for Insomnia (MRTI), focusing on relaxation techniques. Night shift nurses in Oregon who experience insomnia and have internet access might be suitable candidates. As an unphased trial, this study allows nurses to explore innovative insomnia treatments and contribute to valuable research.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it does exclude some current treatments for insomnia. It's best to discuss your specific medications with the trial coordinators.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that both CBTI (Cognitive Behavioral Therapy for Insomnia) and MRTI (Multicomponent Relaxation Therapy for Insomnia) safely and effectively help people with insomnia sleep better.

Studies have found that CBTI significantly reduces insomnia symptoms and improves sleep quality. One major benefit is its lack of side effects, unlike some sleep medications. It also helps maintain better sleep over time.

MRTI, which includes methods like mindfulness meditation, also shows promise. Research indicates that mindfulness practices can improve sleep quality and reduce time spent awake at night. This suggests MRTI can enhance sleep without causing harm.

Both treatments are safe and proven to aid sleep, making them excellent options for those dealing with insomnia. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Cognitive Behavioral Therapy for Insomnia (CBTI) and Multicomponent Relaxation Therapy for Insomnia (MRTI) because they offer non-drug-based approaches to managing Shift Work Sleep Disorder. Unlike traditional treatments like sleeping pills, which can have side effects and risk of dependency, CBTI focuses on changing sleep habits and thought patterns to improve sleep quality. Meanwhile, MRTI combines relaxation techniques to help ease stress and promote better sleep. These therapies provide promising alternatives by targeting the root causes of insomnia without medication.

What evidence suggests that this trial's treatments could be effective for improving insomnia in night shift working nurses?

This trial will compare two treatments for Shift Work Sleep Disorder: Cognitive Behavioral Therapy for Insomnia (CBTI) and Multicomponent Relaxation Therapy for Insomnia (MRTI). Research has shown that CBTI can improve sleep for extended periods, with benefits lasting up to 10 years after treatment. However, studies on shift workers, such as night shift nurses, have yielded mixed results, with some evidence suggesting it might not be as effective for them. MRTI, which includes mindfulness practices, has been shown to help people with insomnia sleep better and feel less stressed. A review of studies found that mindfulness meditation can reduce the time people stay awake during the night. Both treatments offer promising options, but results can vary based on individual situations. ^{1 2 6 7 8}

Published Research Related to This Trial

A cognitive behavioral group intervention for insomnia (CBT-I) was effective in improving sleep quality and reducing insomnia symptoms among 19 shift workers over a 6-month follow-up period, with significant enhancements in sleep onset latency and overall sleep efficiency.

Participants reported better sleep on their days off compared to work days, but the CBT-I treatment improved sleep quality on both types of days, indicating its potential effectiveness for shift workers.
