Summary
Cognitive Behavior Therapy (CBT) and Acceptance and Commitment Therapy (ACT) both effectively treat insomnia. CBT showed faster improvement, while ACT demonstrated significant long-term gains, offering a viable alternative for some patients.
Area of Science:
- Psychology
- Clinical Psychology
- Behavioral Science
Background:
- Insomnia is a prevalent sleep disorder affecting millions worldwide.
- Cognitive Behavior Therapy (CBT) is a well-established treatment for insomnia.
- Acceptance and Commitment Therapy (ACT) offers a novel approach focusing on acceptance and values-based action.
Purpose of the Study:
- To compare the efficacy of ACT-based protocols versus CBT for insomnia in adults.
- To evaluate treatment outcomes at posttreatment and 6-month follow-up.
Main Methods:
- A randomized controlled trial involving 227 adults with insomnia.
- Participants were assigned to six weekly group sessions of ACT (n=76), CBT (n=76), or a waitlist control (WL; n=75).
- Insomnia severity, treatment response, remission, and daytime functioning were assessed.
Main Results:
- Both ACT and CBT significantly reduced insomnia severity with large effect sizes, maintained at follow-up.
- CBT demonstrated superiority over ACT in reducing insomnia severity at posttreatment and follow-up (small effect size).
- ACT showed significant improvements compared to WL, with delayed but substantial long-term gains in response and remission rates.
Conclusions:
- Both CBT and ACT are effective insomnia treatments, with CBT offering quicker results.
- ACT is a valuable long-term treatment option, particularly for individuals who struggle with traditional behavioral techniques.
- ACT's effectiveness highlights its potential as a viable alternative for managing chronic insomnia.

All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it.

Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
