Background The population of elder people are increasing and life expectancy has been extended due to improved public health services and medical interventions. Because increased life expectancy in the elderly has been assured, it is important to improve their quality of life (QOL). In measuring QOL, the World Health Organization (WHO) has developed the WHO Quality of Life–BREF (WHOQOL-BREF). The WHOQOL-BREF was developed in the context of four domains of QOL: physical, psychological, social and environmental. The objective of this study was to evaluate the validity and reliability of the WHOQOL-BREF to assess the QOL in the elderly. Methods A cross-sectional design was conducted in Mampang Sub-district, South Jakarta. During 2 months (October and November 2005) assessment, 306 elderly (age ³60 years, mobile, well communication and not in terminal condition) agreed to participate in the study. Information on age, gender, education, marriage status, and quality of life were collected by ten trained interviewers. Results This study showed that the score distribution in each domain of the WHOQOL-BREF was symmetrical with no floor or ceiling effect. Furthermore, all domain scores indicated excellent discriminant validity, construct validity, and good internal consistency. Nevertheless, two items related to negative feelings and sexual activity had a weak correlation with psychological and social domain. The two items may need to modify to avoid misunderstanding for older people. Conclusion With few modification the WHOQOL-BREF assessment was valid and reliable for measuring QOL in the elderly.
