摘要:Abstract The objective of this study is to identify sleep quality and factors that influence sleep quality amongst older persons in institutions. The participants from this cross-sectional study were selected using a convenience sampling strategy from eight government-funded elderly institutions in Malaysia. The participants are 331 elderly aged 60 years and above. The results indicated that the sleep quality among elderly in institutions is poor, and pain emerged as the main predictor of sleep quality for all groups (normal, mild cognitive impairment and dementia). Dementia has two other main predictors which are role limitation due to emotional problems and emotional well-being.
