Discussion
The results of this study indicate that PSQI-P had acceptable psychometric properties include good reliability and validity in clinical and non-clinical samples. Reliability was higher in the clinical sample than in control group.
PSQI-P reliability in our study were somewhat higher than or approximately similar to other PSQI translations(5-8). Although assessment of subjective sleep quality in sleep disordered sample, other clinical condition or general population is an important issue for health care system, but many previous studies have not chosen sleep clinic patients as an obvious population for validation of the PSQI. PSQI-P reliability in our study were higher than Shochat Dsc et al. study(5). Similar to Shochat Dsc study our sample included a various clinical sleep disorders population such as insomnia, snoring, suspected obstructive sleep apnea, narcolepsy and hypersomnia. Our data suggest that poor sleep quality is a common findings in patients suspected to sleep apnea like previous studies(18)and other sleep disorders. Therefore, PSQI-P could be as a screener instrument and one of first line subjective evaluation in all sleep clinic sample e.g. sleep apnea in Persian population. …show more content…
may be due to the unilingual population that typically seen at our sleep clinic in west of Iran. All patients in this study were fluent in Persian and Persian was the native language for almost all sample.
Similar to reliability result, validity of the PSQI-P was found to be high. Good concurrent validity was confirmed by significant differences between clinical and non-clinical samples in PSQI-P scores. Patients referred to the sleep clinic showed significant higher scores, indicating lower sleep quality compared to
