How do you interpret PSQI scores?
Scoring. The PSQI includes a scoring key for calculating a patient’s seven subscores, each of which can range from 0 to 3. The subscores are tallied, yielding a “global” score that can range from 0 to 21. A global score of 5 or more indicates poor sleep quality; the higher the score, the worse the quality.
What is the PSQI test?
The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a l-month time interval.
Is the Pittsburgh Sleep Quality Index free?
The Pittsburgh Sleep Quality Index (PSQI): A new instrument for psychiatric research and practice. Psychiatry Research, 28(2), 193-213. This copyright in this form is owned by the University of Pittsburgh and may be reprinted without charge only for non-commercial research and educational purposes.
Is the Pittsburgh Sleep Quality Index validated?
The PSQI measures sleep quality for the month period just preceding the interview. But, it has been found to be a valid and reliable measure of insomnia in some populations [5, 7–9].
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%.
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.
How many questions are there in PSQI?
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. The 19 self-rated items are combined to form seven “component” scores, each of which has a range of 0-3 points.
Who made PSQI?
Daniel J. Buysse
The PSQI was developed by Daniel J. Buysse and collaborators to measure quality of sleep and to help discriminate between individuals who experience poor sleep versus individuals who sleep well.

Is PSQI a Likert scale?
BEST TOOL: The Pittsburgh Sleep Quality Index (PSQI) is an effective instrument used to measure the quality and patterns of sleep in the older adult. The client self rates each of these seven areas of sleep. Scoring of the answers is based on a 0 to 3 scale, whereby 3 reflects the negative extreme on the Likert Scale.
What is a normal sleep latency?
Sleep latency, or sleep onset latency, is the time it takes a person to fall asleep after turning the lights out. On average, a healthy person takes between 10 and 20 minutes to fall asleep.
What is a good sleep quality score?
Sleep score takes into account both the duration of the sleep and the quality of the recovery. Sleep score 100 means your sleep is excellent: you have slept enough and most of it has been restorative. 80–99 stand for good sleep, 50–79 for moderate and 0–49 for poor sleep.
What is the reliability of the PSQI index?
VALIDITY AND RELIABILITY: The PSQI has internal consistency and a reliability coefficient (Cronbach’s alpha) of 0.83 for its seven compo-nents. Numerous studies using the PSQI in a variety of older adult populations internationally have supported high validity and reliability.
What are the 7 dimensions of the PSQI?
The PSQI is a 24-item scale that measures sleep disturbances along 7 dimensions: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. Scores from these seven areas are added together into a global score.
Is the PSQI valid for multinight recording?
There has been little research validating the PSQI with respect to multinight recording as with actigraphy, and more validation is needed in samples not specifically selected for clinical disturbance. Also, the degree to which the PSQI scores may reflect depressive symptoms versus actual sleep disturbance remains unclear.
Is the PSQI a valid measure of insomnia?
The PSQI measures sleep quality for the month period just preceding the interview. But, it has been found to be a valid and reliable measure of insomnia in some populations [ 5, 7 – 9 ]. The statistical package SPSS version 16.0 (SPSS Inc., Chicago, USA) was used.
