Is the sleep latency reliable? (SHHS2)

latreliable under Sleep Monitoring/Polysomnography/Signal Quality in SHHS variables

Sleep latency will be considered reliable when a change in lights status (on/off) shows a clear transition (even if reversed- off to on) prior to the onset of sleep.

Pittsburgh Sleep Quality Index: Sleep latency component subscore

pqplaten under Sleep Questionnaires/Pittsburgh Sleep Quality Index (PSQI) in MROS variables

Subscore based on 2 items from Pittsburgh Sleep Quality Index, with a range of 0-3. A score of "0" indicates no difficulty, while a score of "3" indicates severe difficulty. Buysse et. al 1989 (PubMed ID: 2748771) Search for all PSQI variables within this dataset
