Summary
This study validated the Sleep Health Scale (SHS) for Portuguese adults, finding it reliable for assessing sleep health indicators. Socio-demographic factors significantly influenced sleep health in the study population.
Area of Science:
- Sleep Science
- Psychometrics
- Public Health
Background:
- Sleep health is an emerging concept requiring further research.
- Validating measurement tools is crucial for assessing sleep health in diverse populations.
- The Portuguese adult population lacked a validated instrument for sleep health assessment.
Purpose of the Study:
- To validate the Sleep Health Scale (SHS) for the Portuguese adult population.
- To assess the reliability and validity of the SHS in this demographic.
- To explore the influence of socio-demographic factors on sleep health.
Main Methods:
- A sample of 540 Portuguese adults (aged 18-90) completed the SHS.
- Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were employed.
- Convergent validity and reliability analyses were conducted.
Main Results:
- The SHS demonstrated good convergent validity (AVE = 0.55) and reliability (α = 0.85 / CR = 0.86).
- Confirmatory factor analysis indicated a well-adjusted model, with minor issues in question 5.
- Socio-demographic variables including age, gender, and literacy significantly impacted sleep health.
Conclusions:
- The Sleep Health Scale (SHS) is a valid and reliable tool for assessing sleep health in Portuguese adults.
- The scale effectively measures various sleep health indicators.
- Future research should explore the link between sleep health and well-being for quality of life improvements.

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

3.0K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

01:24Substance Use Disorders Affecting Sleep
466
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.

7.1K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.

510
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
975
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.
