Psychometric assessment of subjective sleep quality using the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J) in psychiatric disordered and control subjects
Abstract
Subjective sleep quality has been identified as an important clinical construct in psychiatric disordered patients. The Pittsburgh Sleep Quality Index (PSQI), one of the most widely used standardized measures to assess subjective sleep quality, generates a global score and scores seven components. The present study psychometrically assessed clinical profiles of subjective sleep quality in 82 control and 92 psychiatric disordered subjects (primary insomnia, n=14; major depression, n=30; generalized anxiety disorder, n=24; and schizophrenia, n=24), using the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J). The overall reliability coefficient of the PSQI-J was high (Cronbach's alpha=0.77). Correlation coefficients between the PSQI-J global and component scores were statistically significant. The PSQI-J global and component mean scores were significantly higher in psychiatric disordered subjects than control subjects, except for the component of sleep duration. Using a cut-off point of 5.5 in the PSQI-J global score, estimations of sensitivity and specificity provided 85.7 and 86.6% for primary insomnia, 80.0 and 86.6% for major depression, 83.3 and 86.6% for generalized anxiety disorder, and 83.3 and 86.6% for schizophrenia, respectively. The present study supports the utility of the PSQI-J as a reliable and valid measure for subjective sleep quality in clinical practice and research.

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.
