Psychometric Properties of the Persian Translation of Pittsburgh Sleep Quality Index
Open accessAbstract
Background: Pittsburgh sleep quality index (PSQI) is one of the most important instruments frequently used to assess sleep quality. This questionnaire is used to assess sleep styles and quality in adults through seven dimensions. Objectives: The study aims to investigate the reliability, validity and factor structure of the Persian version of PSQI. Materials and Methods: A Survey method with quantitative analytic approach was used in this research. A sample of 415 employees of Kerman hospitals participated in this study and filled the questionnaire. Forward-backward method was applied to translate the questionnaire from English to Persian. The following aspects of the Persian version of PSQI were evaluated: internal consistency (using Chronbach’s alpha), concurrent validity (correlation with GHQ-28), and factor structure of the questionnaire. Results: Mean age of the participants was 35.18 years, and participants’ average year of education was 15.3. The Chronbach’s alpha coefficient was 0.55. According to the factor analysis, three factors were extracted accounting for 63.485% of the total variance. There was a significant correlation among different dimensions of the Persian version of PSQI. Concurrent validity analysis showed that PSQI and GHQ-28 were correlated significantly. Conclusions: The Persian version of PSQI exerted a satisfactory validity and reliability in our sample.

The Abstract and Discussion report that this study assessed the Persian PSQI’s psychometric properties in an Iranian hospital sample and found satisfactory validity and reliability. The Measures section also cites prior Iranian validation studies of the GHQ-28. The source does not establish that every questionnaire used in the citing study had been assessed in Iran.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
