Increases in duration of first uninterrupted sleep period are associated with improvements in PSQI-measured sleep quality.

ABSTRACT:

Objective

Urology clinical trials assessing bladder function have relied on the self-reported duration of the first uninterrupted sleep period (FUSP) as a proxy outcome for sleep, but the relationship between this measure and more conventional self-reported measures of sleep is unknown. In this study, we examined the association between changes in FUSP and a widely used self-reported measure of sleep, the Pittsburgh Sleep Quality Index (PSQI).

Methods

We conducted post hoc (secondary) analyses of unpublished data from a previously published randomized clinical trial (NCT00477490) of desmopressin (a medication used to treat nocturia) and examined relationships between baseline and 4-week change in FUSP and PSQI global and subscale scores for participants (N = 580 to N = 606)
