Proportion of Participants With Poor Sleep Quality (PSQI Global Score >5)
Sleep quality over the preceding month is assessed with the Turkish version of the Pittsburgh Sleep Quality Index (PSQI), a self-report questionnaire. Its 7 component scores (each 0-3) are summed into a global score ranging from 0 to 21, with higher scores indicating worse sleep quality. Participants with a global score \>5 are classified as having poor sleep quality and those with a score of 5 or less as having good sleep quality. The outcome is reported as the percentage of participants with poor sleep quality.
Time frame: At enrollment (single assessment; the PSQI covers the preceding 1 month)
PSQI Global Score
Global score of the Turkish version of the Pittsburgh Sleep Quality Index (sum of 7 component scores; range 0-21; higher scores indicate worse sleep quality), reported as a continuous variable.
