Journal Title: Indian Journal of Nutrition - Year 2017, Vol 4, Issue 4
Abstract
Background: Aging is an irreversible biological change that occurs throughout an individual’s life and continues relentlessly until death. Although there is no certain age, 65 years is usually accepted as the beginning of old age. Chronic diseases cause medical, social, and psychological problems that limit the activities of elderly people in the community and decrease their Quality of Life (QOL). Aim: With the above background present study was conducted with the aim to assess the quality of life in elderly by using WHOQOL, OPQOL-35 and CASP-19 scales and to compare the reliability and responsiveness of these scales. Design and methods: Total 30 elderly subjects above the age of 65 years were purposively selected for the study from urban areas of Faridabad on the basis of inclusion and exclusion criteria. Three standard questionnaires of QOL (WHOQOL-BREF, OPQOL-35 and CASP-19) were used for collection of data from subjects. Anthropometric measurements were also taken using standard protocols. Follow up was done two times at 15 days interval. Data was analyzed by SPSS vs. 20.0. Results: Data revealed that the mean age of study subjects was 68.80±3.94 years with minimum age 65 years and maximum age 80 years. Majority of subjects (63.3%) were females. All the three scales were consistent. There was no significant difference in any domains of WHOQOL-BREF, OPQOL-35 and CASP-19 at both follow up. Cronbach’s alpha test of reliability revealed that WHOQOL-BREF received 0.78, 0.82 and 0.72 alpha values at baseline and 2 follow up respectively, OPQOL-35 had received minimum alpha value that was 0.31, 0.45 and 0.482 and CASP-19 had Cronbach’s alpha value around 0.69 at baseline as well as in follow ups. Conclusion: Out of three QOL scales, WHOQOL-BREF scale come out to be the most reliable scale in this community.
