Quality of Life (QOL), Nursing Home Residents, Vietnam.

Background: The aging of Vietnam's population has led to a growing demand for institutional care, underscoring the need to understand the quality of life (QoL) among older adults living in nursing homes. This study aims to identify and analyze factors associated with QoL, with a focus on demographic characteristics, health- related status, and perceived social support.

Methods: A cross-sectional study will be conducted in 2025 using convenience sampling from selected nursing homes in Hanoi. Participants will be aged 60 years or older, have resided in the facility for at least three months, be cognitively capable of communication, and provide informed consent. Data will be collected via structured face-to-face interviews using standardized instruments, including the WHOQOL- BREF, Barthel Index, Multidimensional Scale of Perceived Social Support (MSPSS), Mini Nutritional Assessment (MNA-SF), Numerical Raiting Scale (NRS) and Geriatric Depression Scale (GDS-15). SPSS version 27 will be used for data analysis, employing descriptive and inferential statistics such as t-tests, ANOVA, Pearson's correlation, and multiple linear regression.

Expected Results: It is anticipated that higher levels of functional independence and perceived social support will be positively associated with better QoL outcomes.

Expected Conclusion/Implications: Findings from this study are expected to contribute to evidence-based nursing practice and inform care planning and policy- making to improve the well-being of older adults in long-term care facilities in Vietnam.
