Summary
A mobile app for Cognitive Behavioral Therapy for Insomnia (CBT-I) is feasible and effective for college students. Most users found the app helpful, leading to reduced insomnia symptoms.
Area of Science:
- Psychology
- Digital Health
- Sleep Medicine
Background:
- Insomnia is prevalent among college students, impacting academic performance and well-being.
- Traditional Cognitive Behavioral Therapy for Insomnia (CBT-I) can be resource-intensive.
- Mobile health applications offer a scalable approach to delivering mental health interventions.
Purpose of the Study:
- To assess the feasibility, acceptability, and efficacy of a self-guided mobile app for CBT-I (CBT-I Coach) in college students.
- To evaluate the impact of the CBT-I Coach app on insomnia symptom severity in a student population.
Main Methods:
- A randomized controlled trial was conducted with 55 college students reporting moderate insomnia.
- Participants were assigned to either a 4-week CBT-I Coach intervention or a wait-list control group.
- Self-report measures of insomnia symptoms were collected biweekly over 8 weeks.
Main Results:
- Nearly 70% of participants rated the app as moderately to extremely effective.
- The intervention group showed a significantly greater reduction in insomnia symptoms compared to the control group (g = 0.88).
- The study demonstrated the feasibility and acceptability of the mobile intervention.
Conclusions:
- Self-guided mobile interventions for insomnia are feasible for college students.
- The CBT-I Coach app demonstrates preliminary efficacy in reducing insomnia symptoms.
- Mobile CBT-I represents a promising avenue for addressing sleep issues in student populations.

An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

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...

01:19Management of Insomnia
231
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.

01:13Insufficient Sleep and Sleep Deprivation
134
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.

146
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...
