Get Pittsburgh Sleep Quality Index 2020-2024

The reliability of the scale is considered good with Cronbach's alpha of 0.83 for the total score. Test–retest reliability is also considered good. The validity of PSQI has been described by the authors as good with a sensitivity of 89.6% and a specificity of 86.5% of patients versus control subjects.

In scoring the PSQI, seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality.

Adding up the average scores of the seven factors gives a global PSQI score from 0 to 21, with 0–4 indicating “good” sleep and 5–21 indicating “poor” sleep. This subjective and straightforward measure of sleep quality may seem oversimplified.

The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval.

Pittsburgh Sleep Quality Index (PSQI) Each of the sleep components yields a score ranging from 0 to 3, with 3 indicating the greatest dysfunction. 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.

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.

Scoring Using a four-point, Likert-type scale, respondents indicate how frequently they exhibit certain sleep behaviors (0 = “few,” 1 = “some- times,” 2 = “often,” and 3 = “almost always”).
