Summary
A cognitive behavioral program effectively prevents insomnia in adolescents at risk. This intervention significantly reduced insomnia incidence and improved sleep quality over 12 months.
Area of Science:
- Sleep Medicine
- Adolescent Health
- Behavioral Science
Background:
- Adolescents with a family history of insomnia and subthreshold symptoms are at high risk for developing the disorder.
- Early intervention is crucial to prevent the transition from subthreshold symptoms to clinical insomnia.
Purpose of the Study:
- To evaluate the efficacy of a brief insomnia prevention program in at-risk adolescents.
- To assess the program's impact on insomnia incidence, symptoms, and related functional outcomes.
Main Methods:
- A randomized controlled trial was conducted with 242 adolescents.
- Participants were assigned to a 4-week insomnia prevention program or a nonactive control group.
- Assessments occurred at baseline, post-intervention, and 6 and 12 months, with blinded assessors and intention-to-treat analysis.
Main Results:
- The intervention group showed a significantly lower incidence of insomnia disorder (5.8% vs. 20.7%, P = .002).
- Participants receiving the program experienced reduced insomnia symptoms, lower stress vulnerability, improved sleep hygiene, and increased total sleep time.
- The intervention group also reported fewer depressive symptoms at 12-month follow-up.
Conclusions:
- A brief cognitive behavioral program is effective in preventing insomnia onset in at-risk adolescents.
- The program improves key vulnerability factors and functional outcomes related to sleep.

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...

01:27Insomnia
251
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.

01:24Substance Use Disorders Affecting Sleep
277
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:13Insufficient Sleep and Sleep Deprivation
574
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

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...

01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
328
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
