Adherence
Self-report sleep quality questionnaires (specifically PSQI, AIS, ISI, MSQ, JSS, LSEQ, SLEEP-50, ESS) demonstrate good internal reliability and construct validity, making them suitable for clinical and epidemiological screening despite objective measures like polysomnography being impractical.
Use validated self-report questionnaires like the PSQI or ISI to assess sleep quality. They are cost-effective, easy to administer, and provide reliable data for screening poor sleepers in both clinical and research settings, especially when objective measures like PSG are not feasible.
GoodSupportsHIGH confidence
Overall, the self-report questionnaires assessing sleep quality from different perspectives have good psychometric properties, with high internal consistency and test-retest reliability, as well as convergent/divergent validity with sleep, psychological, and socio-demographic variables.
Why this rating
Based on a systematic review of 49 articles covering multiple validated questionnaires across diverse populations.
