Psychosocial Predictors of Sleep Quality in Residents of Nursing Homes

This article examines the cross-sectional and long-term prediction of sleep quality (SQ) of 167 older nursing-home residents (80% females, 69-100 years), who participated in the study in 2008 and 2016. SQ was assessed in 2016 by the Pittsburgh Sleep Quality Index (PSQI); Total PSQI was found to be greater than 5 in 71% of participants. The domains of Subjective SQ and Daytime Functioning were relatively good, while Sleep Efficiency was most impaired. The observed set of predictors significantly explained 7-13% of PSQI variance cross-sectionally and 12-18% in the long-term effects analyses. The structure of predictors differed across SQ domains, in both the cross-sectional and the long-term effects analyses, and between the two, indicating the important impact of changes in psychophysiological functioning for current SQ of older adults.
