Sleep Assessment Methods
Research gap analysis derived from 2 medicine papers in our local library.
The gap
Most studies rely on subjective measures like PSQI without validating against objective methods such as polysomnography or actigraphy in various populations including PLHIV, RA patients, children post-cardiac surgery, and obstructive sleep apnea patients.
Consensus across the literature
The papers collectively establish the need for more objective sleep assessment but leave open specific validation criteria and populations to be studied.

- Poor sleep quality and associated factors people living with HIV on follow-up in Benin's National Teaching Hospital: a cross-sectional study (2026) · doi
The study measured sleep quality using the Pittsburgh Sleep Quality Index (PSQI) in a single-center setting at CNHU-HKM in Benin, but did not employ objective sleep assessment tools such as polysomnography or actigraphy to validate subjective sleep quality measurements in people living with HIV on antiretroviral therapy.
