“…The PSQI demonstrated good convergent validity in our sample. Greater sleep dysfunction was significantly associated with higher levels of depression and anxiety, similar to previous research [ 70 ]. The PSQI global score and many components were found significantly and moderately associated with RRS.…”

Objectives: Evaluate the psychometric properties and structural validity of the Filipino version of the Pittsburgh Sleep Quality Index (PSQI) among Filipino domestic workers (FDWs). Methods: In Study 1, 131 FDWs completed PSQI and other scales, along with 10-day actigraphic assessment with accompanying electronic daily sleep dairy. A subsample of 61 participants completed follow-up assessment after 10 days. In Study 2, 1363 FDWs were recruited and randomized into two halves. Exploratory factor analysis (EFA) and Confirmatory factor analysis (CFA) were used in the two halves, respectively. Results: In Study 1, the Cronbach’s alpha of the PSQI was 0.63 at baseline and 0.67 at follow-up. Test-retest reliability for the PSQI global score based on intraclass correlation was 0.63. Convergent validity was supported by the significant associations between the PSQI global score, PSQI components scores, sleep patterns from the daily sleep diary, and measures of depression, anxiety, and rumination. Small correlations between the PSQI global score and measures of daytime sleepiness, social support, and self-reported height, supported discriminant validity. In Study 2, EFA yielded two PSQI factors with acceptable factor loadings. CFA established that this two-factor model, comprised of perceived sleep quality and sleep efficiency, evidenced better model fit than alternative models tested. The Cronbach’s alpha of two factors was 0.70 and 0.81, respectively. Conclusions: The PSQI demonstrated good internal consistency of two factors, and good convergent, and divergent validity. Results can be referenced in future studies to measure and screen sleep dysfunction among clinical and non-clinical populations in the Philippines.

“…However, their study was the only validation test of the Korean version of the PSQI. The cut-off point of the PSQI translated into various languages was 5 [ 20 – 22 ] and the study using the Korean version of the PSQI still sets the standard for poor sleep quality to 5. Therefore, we applied two cut-off scores in this study [ 23 , 24 ].…”

ObjectivePoor sleep quality has a number of significant negative effects on daytime function. However, few studies have examined sleep quality in patients with dizziness. Here, we investigated the potential association between sleep quality and various types of dizziness.Subjects and methodsWe examined dizziness and sleep disturbance in 237 patients experiencing dizziness using Korean versions of the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), and Dizziness Handicap Inventory (DHI). All participants were classified as having benign paroxysmal positional vertigo (BPPV), Ménière’s disease (MD), vestibular neuritis (VN), vestibular migraine (VM), psychogenic dizziness (PD), or Other.ResultsThe mean PSQI and ISI scores were highest in the PD group. The rate of sleep disturbance was highest in the Other group when the cut-off score for each questionnaire was set differently, except ISI ≥ 15. The correlation between DHI and sleep disturbance indices was highest in the VM group. Multivariate regression showed that PSQI score and DHI-E score were significantly related to the PD and Other groups, while the Other group was significantly related to the ISI score.ConclusionThe findings of this study strongly suggest that there are associations between sleep quality and some disease subtypes associated with dizziness. Therefore, it is important to consider sleep disturbance in patients with psychogenic dizziness, such as phobic postural vertigo and chronic subjective dizziness, or nonspecific dizziness.

“…Subjective sleep quality questionnaires. To capture the general sleep quality of the last month, we administered the Pittsburgh Sleep Quality Index (PSQI) 14,32 and the Athens Insomnia Scale (AIS) 15,33 . Additionally, in Study 2, we administered a Sleep diary 34 to assess the sleep quality of the last one-two weeks, and the Groningen Sleep Quality Scale (GSQS) 35,36 to capture the sleep quality of the night prior testing.…”

the role of subjective sleep quality in cognitive performance has gained increasing attention in recent decades. In this paper, our aim was to test the relationship between subjective sleep quality and a wide range of cognitive functions in a healthy young adult sample combined across three studies. Sleep quality was assessed by the Pittsburgh Sleep Quality Index, the Athens Insomnia Scale, and a sleep diary to capture general subjective sleep quality, and the Groningen Sleep Quality Scale to capture prior night's sleep quality. Within cognitive functions, we tested working memory, executive functions, and several sub-processes of procedural learning. To provide more reliable results, we included robust frequentist as well as Bayesian statistical analyses. Unequivocally across all analyses, we showed that there is no association between subjective sleep quality and cognitive performance in the domains of working memory, executive functions and procedural learning in healthy young adults. Our paper can contribute to a deeper understanding of subjective sleep quality and its measures, and we discuss various factors that may affect whether associations can be observed between subjective sleep quality and cognitive performance.
