Abstract
BackgroundOld age is associated with reduced physical ability. It is necessary to measure and evaluate the physical activity of older people. Implementing appropriate requires a valid and reliable tool. Physical Activity Scale for the Elderly (PASE) is the frequently used self-reported physical activity assessment for older adults. Therefore, this study aimed to determine the translation validity and reliability of the Persian version of the Physical Activity Scale for the Elderly.MethodsThis study is a methodological, descriptive applied research was conducted on 300 older people. The translation process of the English version of PASE into Persian was carried out according to the process of translation and adaptation of scale recommended by the World Health Organization. The reliability of the scale was examined by calculating the Cronbach’s alpha, Pearson, and intraclass correlation coefficient (ICC). The reliability and validity of the scale were evaluated by following the “Consensus-Based Standards for the Selection of Health Status Measurement Instruments” (COSMIN) checklist. To assess the face and content validity, impact score (IS), the content validity ratio (CVR), and the content validity index (CVI) were determined. A confirmatory factor analysis was also performed.ResultsThe experts approved the quality of the Persian version of PASE. The reliability was calculated with a Cronbach’s alpha of 0.94, an ICC of 0.99, and a test-retest correlation coefficient of 0.94. The qualitative and quantitative face validity of all questions by expert judgment and IS of greater than 1.5 was considered. Also, CVR and CVI scores of all questions were higher than 0.6 and 0.79, respectively. Confirmatory factor analysis revealed a good fit for the original three-factor structure.ConclusionsThe Persian or Farsi version of PASE was shown to have acceptable validity and reliability. This tool is suitable for measuring the physical activity level in the Persian elderly language special in clinical environments and therapeutic interventions.
Highlights
Old age is associated with reduced physical ability
Regular physical activity in old age can prevent osteoporosis and its consequences such as femoral and pelvic bone fractures, obesity, depression and colon cancer, and, in general, the biological changes associated with ageing [9, 10]
The results indicated that Physical Activity Scale for the Elderly (PASE) can be considered as an appropriate tool for measuring the physical activity of the elderly [25]
Summary
Old age is associated with reduced physical ability. This study aimed to determine the translation validity and reliability of the Persian version of the Physical Activity Scale for the Elderly. The life expectancy of older people is rising around the world [2]. Having an active life makes older people healthy and independent [11]. Regular physical activity, such as walking, reduces dependence on other family members and caregivers, accelerates socialization and, improves mental health [12,13,14,15,16], while immobility is one of the top 10 causes of death in the world [17]. An inactive life is among the main causes of chronic diseases such as cardiovascular disease, diabetes mellitus, etc. [18]
