Validity and Reliability of the Short Form- 36 Items Questionnaire as a Measure of Quality of Life in Elderly Iranian Population

Abstract

Abstract:The utility of The SF-36 questionnaire for evaluation of health related quality of life was not clear in elderly people. The Cross-Sectional study was designed and Iranian version of The SF-36 was administered to random sample of 100 old subjects over 60 years old. Finding showed good internal consistency over 0.7 for all subscales of questionnaire. Convergent validity was obtained for all subscales with comparison for General Health Questionnaire-28 (GHQ-28) but was not strongly at 2 subscales Role emotional and Role physical. Discriminant validity was addressed for gender but for age groups role emotional, mental health and general health subscales were not different significantly. A principal component analysis was leaded one factor structure. Evidence for reliability of the questionnaire was good. But validity appeared moderate satisfactory. However this questionnaire seems the only measure for assessment of health related quality at life among elderly population.

Translation and Validation of the Activities of Daily Living Scale with Iranian Elderly Cancer Patients Treated in an Oncology Unit

“…In this study we found that the Iranian version of the ADL index has relatively good criterion validity because the scores of Katz's ADL were correlated with scores of physical function of SF 36. The validity and reliability of SF 36 among the Iranian elderly population was approved previously (Eshaghi et al, 2006). The Katz ADL is an effective tool that applied in older adults (Wallace and Shelkey, 2008).…”

“…Psychometric evaluation and factor analysis of these components were performed by (Stewart et al, 1981). And the validation of the Persian version SF-36 was conducted in an Iranian older population (Eshaghi et al, 2006).…”

The Prevalence of Depression and Its Risk Factors Among Malay Elderly in Residential Care

“…If depression is not prevented, the elderly may fail to adjust and adapt well to their life in the institution, resulting in a low level of life satisfaction and quality (Eshagi et al, 2006;Blazer and Hybels, 2005;De Souza et al, 2008;Farzianpour et al, 2012;Jampawai et al, 2011). Furthermore, if depression is not treated effectively, it may impair cognitive, physical and psychological to be worsen, delayed recovery from medical illness, decreased social functioning, increased health care requirement and suicide (Farzianpour et al 2012;De Souza et al, 2008;Farzianpour et al, 2014;Dahlan et al, 2010).…”

“…Its prevalence among elderly people is common, but it often has been under diagnosed and frequently has been inadequately treated (Kim et al, 2009;Eshagi et al, 2006;Farzianpour et al, 2012). Globally, the prevalence of depression among elderly is 10-15.0% due to such issues as lack of transportation, loss of employment, loss of friends and acquaintances, loss of loved ones, isolation, bereavement and the existence of a variety of health problems (Krishnaswamy, 1997;Blazer and Hybels, 2005;Onya and Stanley, 2013).…”

The Effect of a Period of Aquatic Therapy Exercise on the Quality of Life and Depression in Aged Males Suffering from Chronic Physical Pains

“…Grades 0 to 100 were designated to the sum total of the eight dimensions of health, with the higher grades signaling a better health condition 26 . The validity and reliability of the questionnaire have been established in numerous studies, and even its Farsi version is available and of acceptable validity and reliability 27 . The depression questionnaire no.1 that contains 21 questions has been made with the intention of evaluating the feedbacks and symptoms of the depressed patients, and its material has been provided based on observation and summarization of common attitudes and signals among the depressed psychiatric patients 28,29 .…”
