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...

Insomnia

79
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.

Insufficient Sleep and Sleep Deprivation01:13

Insufficient 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.
Sleep deprivation is a more severe form of sleep loss...

Management of Insomnia

234
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...

Area of Science:

  • Behavioral Science
  • Public Health
  • Digital Health

Background:

  • Adolescents require 8-10 hours of sleep nightly, but most fall short, leading to negative health outcomes.
  • Poor sleep in adolescents is a public health concern linked to reduced physical activity, risk-taking, depression, and anxiety.
  • Current adolescent sleep interventions are often ineffective due to lack of engagement, time commitment, and theoretical basis.

Purpose of the Study:

  • To determine the acceptability, feasibility, and preliminary impact of SleepWise, a web-based, person-based sleep intervention for adolescents.
  • To explore the effect of participant incentivization on engagement, acceptability, and sleep quality within the intervention.

Main Methods:

  • A feasibility trial involving 90 adolescents (13-17 years) in two randomized controlled trials (one incentivized, one not).
  • SleepWise intervention developed using a person-based approach, assessing acceptability and sleep quality via questionnaires.
  • Mixed-methods process evaluation included automated engagement tracking and semistructured interviews for feedback.

Main Results:

  • High acceptability and similar engagement levels were reported in both incentivized and non-incentivized trials.
  • SleepWise demonstrated medium to large effect sizes for improving adolescent sleep quality.
  • Incentivization did not significantly impact engagement or sleep quality, with a larger effect size in the non-incentivized trial.

Conclusions:

  • SleepWise is an acceptable and potentially effective web-based intervention for adolescent sleep.
  • The study suggests incentivization is not crucial for engagement or improving sleep quality.
  • SleepWise shows potential to meet the need for innovative, personalized adolescent sleep interventions.
