What is the average PSQI score?
The PSQI global score has a possible range of 0-21 points. Actual scores ranged from 0 to 20 points, with an overall group mean of 7.4, median of 6.0, and SD of 5.1.
Is the PSQI valid?
Conclusion: The PSQI has a high test-retest reliability and a good validity for patients with primary insomnia.
How do you interpret PSQI scores?
The PSQI questions are rated from 0 = no difficulty to 3 = severe difficulty, generating scores that correspond to the domains of the scale. The scores range from 0 to 21 and the authors suggest that a score >5 be considered as a significant sleep disturbance. Time to complete PSQI scale: 5–10 min.
How is PSQI calculated?
The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality. Traditionally, the items from the PSQI have been summed to create a total score to measure overall sleep quality.
What is a good PSQI score?
> 5
The sleep component scores are summed to yield a total score ranging from 0 to 21 with the higher total score (referred to as global score) indicating worse sleep quality. In distinguishing good and poor sleepers, a global PSQI score > 5 yields a sensitivity of 89.6% and a specificity of 86.5%.
Is the PSQI qualitative or quantitative?
The PSQI is practical and brief, returning a single score representing overall sleep quality, which incorporates qualitative and quantitative aspects of sleep; scores above 5 are suggested as indicative of a potential sleep problem.
How many questions are on the PSQI?
19
The Pittsburgh Sleep Quality Index (PSQI) contains 19 self-rated questions and 5 questions rated by the bed partner or roommate (if one is available). Only self-rated questions are included in the scoring.
What is a good score on the PSQI?
The sleep component scores are summed to yield a total score ranging from 0 to 21 with the higher total score (referred to as global score) indicating worse sleep quality. In distinguishing good and poor sleepers, a global PSQI score > 5 yields a sensitivity of 89.6% and a specificity of 86.5%.
What is PSQI used for?
The PSQI is often used as a global measure of self-reported sleep disturbance in people with schizophrenia spectrum disorders, but the validity of the PSQI (English version) as a global measure of sleep disturbance in this population has, to our knowledge, not been evaluated.
Is PSQI qualitative or quantitative?
What is the global PSQI score?
Global PSQI Score Assessment The 19 items are divided into seven component scores that reflect the severity of various sleep problems in the following aspects: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleep medication and daytime dysfunction.
What is good sleep hygiene?
Be consistent. Go to bed at the same time each night and get up at the same time each morning, including on the weekends. Make sure your bedroom is quiet, dark, relaxing, and at a comfortable temperature. Remove electronic devices, such as TVs, computers, and smart phones, from the bedroom.
What is the Pittsburgh sleep quality index (PSQI)?
Despite the prevalence of sleep complaints among psychiatric patients, few questionnaires have been specifically designed to measure sleep quality in clinical populations. The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval.
What does PSQI stand for?
The Pittsburgh Sleep Quality Index (PSQI) (Buysse et al., 1989) is a brief, validated instrument that measures sleep quality. It is a nineteen item self assessment of sleep quality and disturbances over a one-month time interval, and generates seven component scores: subjective sleep quality, sleep latency,…
How useful is the PSQI in the diagnosis of sleep apnea?
A global PSQI score greater than 5 yielded a diagnostic sensitivity of 89.6% and specificity of 86.5% (kappa = 0.75, p less than 0.001) in distinguishing good and poor sleepers. The clinimetric and clinical properties of the PSQI suggest its utility both in psychiatric clinical practice and research activities.
