Abstract

Cognitive decline is one of the common problems experienced by older adults. One factor that may influence cognitive function is sleep quality. Poor sleep quality can disrupt brain recovery processes, memory consolidation, concentration, and thinking abilities, thereby potentially contributing to cognitive decline in the elderly. This study aimed to determine the relationship between sleep quality and cognitive function among older adults at Shisetsu The Season, Osaka, Japan. This study employed a quantitative non-experimental design with a cross-sectional approach. The sample consisted of 30 elderly participants selected through total sampling based on the inclusion and exclusion criteria. The instruments used were the Pittsburgh Sleep Quality Index Japanese Version (PSQI-J) to assess sleep quality and the Hasegawa Dementia Scale-Revised (HDS-R) to measure cognitive function. Data were analyzed using the Spearman Rank correlation test. The results showed that the majority of respondents had poor sleep quality, accounting for 20 respondents (66.7%), and poor cognitive function, accounting for 25 respondents (83.3%). The Spearman Rank test revealed a p-value of 0.000 (<0.05) and a correlation coefficient of 0,632 indicating a strong positive relationship between sleep quality and cognitive function. The better the sleep quality of older adults, the better their cognitive function. In conclusion, there is a significant relationship between sleep quality and cognitive function among older adults at Shisetsu The Season, Osaka, Japan.
