Development and psychometric properties of the age-friendly hospitals scale in older adults.

Age-friendly Primary Health Care by the World Health Organization (WHO) provided a framework to guide countries in developing concrete and appropriate care in the health system, including encouraging the development of an Age-Friendly Hospital (AFH) care network. The study aimed to develop and evaluate the psychometric properties of the AFH scale (AFHS) in older adults. A cross-sectional study collected and analyzed data from 330 older adults between June 2018 and June 2019. The instrument was developed and validated according to the proposed guidelines. The study involved item generation and scale development, including content and face validity, pilot testing, exploratory factor analysis (EFA), internal consistency, and test-retest reliability. EFA was performed using principal axis factoring with a promax rotation. The original model of four factors and 22 items was conducted. Three factors with eigenvalues greater than one were extracted, and the scree plot examination confirmed the retention of three factors with 22 items after performing EFA. Using the EFA, we identified three main factors: care processes, communication and service, and physical environment. The developed scale can contribute to establishing AFH and quality healthcare institutions. It may be a valuable reference for healthcare facilities to evaluate and enhance their services, considering factors like limited resources and workforce. Furthermore, this scale can facilitate continuous improvement and long-term development of age-friendly healthcare institutions.
