Validity and reliability of the Turkish version of Geriatric Health Promotion scale

Abstract

Background: A measure for healthy lifestyle behaviours of older adults would enable the development of effective and target-based health promotion strategies. Aim: This study aimed to test the validity and reliability of the Turkish version of Geriatric Health Promotion scale among older people in Turkey. Design: This was a methodological study that was conducted between June and August 2018. Methods: A total of 321 volunteer older individuals, who were admitted to local health centres, participated in this study. A questionnaire, including sociodemographic data form, and the Geriatric Health Promotion scale were used to collect data. Content and construct validity was established using validity analyses. Results: The reliability of the scale was confirmed by its internal consistency (? =.82) and test-retest reliability (0.86). Exploratory factor analysis for the six-factor construct explained 64.7% of the total variance. Factor loads of each item ranged from 0.44 and 0.91. Confirmatory factor analysis indicated that the theoretical constructs had a perfect fit with data obtained. These data establish that the Turkish version of the Geriatric Health Promotion scale was valid and reliable. Conclusion: The Turkish version of the Geriatric Health Promotion scale is a reliable and valid instrument that can be used in the evaluation of health-promoting behaviours among older individuals. © 2020 John Wiley & Sons Australia, Ltd.
