Summary
Bedtime procrastination significantly predicts insomnia severity. The Persian version of the Bedtime Procrastination Scale (BPS) demonstrates strong validity and reliability for assessing this sleep-disrupting behavior.
Area of Science:
- Psychology
- Sleep Science
- Health and Well-being
Background:
- Bedtime procrastination is linked to insufficient sleep and negative health outcomes.
- Understanding its psychometric properties is crucial for accurate assessment.
Purpose of the Study:
- To validate the Persian version of the Bedtime Procrastination Scale (BPS).
- To examine the predictive role of bedtime procrastination in sleep-related problems.
Main Methods:
- Validated the factor structure and psychometric properties of the Persian BPS using Confirmatory Factor Analysis.
- Employed hierarchical regression analysis to assess the relationship between procrastination and insomnia severity.
- Utilized the Insomnia Severity Index (ISI) and Tuckman Procrastination Scale (TPS) for comprehensive assessment.
Main Results:
- The two-factor model (excluding item 3) proved to be the most suitable structure for the Persian BPS.
- The Persian BPS demonstrated acceptable reliability and validity.
- Bedtime procrastination emerged as a significant predictor of insomnia severity.
Conclusions:
- The Persian version of the BPS is a reliable and valid instrument for measuring bedtime procrastination.
- This validated scale can be effectively used in research and clinical settings within the Persian-speaking community.

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

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.

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...

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...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
