Psychometric evaluation of the elderly mobility scale in Indonesia.

BACKGROUND

The Elderly Mobility Scale (EMS) is widely used to identify mobility limitations in older adults, though it has not been validated in Indonesia.

AIM: To evaluate the reliability and validity of the Indonesian version of the EMS (EMS-I).

METHOD: A cross-sectional design involving 230 older adults in South Tangerang City, Indonesia, was used. The EMS was translated and culturally adapted following a multistage process. Psychometric testing included content validity, exploratory, and confirmatory factor analysis.

RESULTS

The participants had a mean age of 70, with 65.7 % female. Results demonstrated high internal consistency (Cronbach's alpha = .942) and item content validity index (I-CVI > .75). Exploratory factor analysis confirmed a unidimensional structure, with confirmatory factor analysis supporting a good model fit.

CONCLUSION

The EMS-I shows high reliability and validity, enabling healthcare professionals to monitor mobility status and facilitate targeted interventions for enhancing well-being in community-dwelling older adults in Indonesia.
