The Sleep Health Index: Correlations with standardized stress and sleep measures in a predominantly Hispanic college
1Department of Psychological Science, The University of Texas Rio Grande Valley, EIEAB 3.208, 1201 West University Drive, Edinburg, TX 78539, USA.
Objectives:
The Sleep Health Index was developed to address limitations with existing sleep scales, particularly in the measurement of healthy sleep in non-clinical populations. The purpose of the current study was to examine this measure in relation to two widely-used sleep scales and two standardized stress scales.
Methods:
A sample of 416 undergraduate students completed an online survey that included the Sleep Health Index, Pittsburgh Sleep Quality Inventory, Insomnia Severity Index, Perceived Stress Scale, and Index of College Students' Recent Life Events.
Results:
Sleep health was negatively correlated with self-perceived stress and life-events (-.41 and- .45, respectively), insomnia severity (-.59), and poor sleep quality (-.58).
Conclusions:
Although other measures assessing sleep health exist, there is a paucity of data-driven support for their validity. Our findings provide support for the Sleep Health Index as a measure of healthy sleep and demonstrate an association between psychological stress and sleep health in an undergraduate student population.
