Cross-Cultural Adaptation and Reliability of the Multidimensional Outcome Expectations for Exercise Scale (MOEES) In Filipino Older Adults

Abstract

Aim: Older adults have varying outcome expectations on why they exercise. The Multidimensional Outcomes Expectation for Exercise Scale (MOEES) is used to measure this; however, it has not been cross-culturally adapted yet in the Filipino setting. Therefore, this study aimed to translate and cross-culturally adapt the MOEES into Filipino and establish its preliminary psychometric properties in community-dwelling Filipino older adults. Methods: This psychometric study had two phases. Phase 1 was the MOEES translation and cross-cultural adaptation following the Beaton Protocol. Phase 2 established preliminary psychometric properties based on the internal consistency and test-retest reliability of the adapted MOEES from 38 conveniently sampled community-dwelling Filipino older adults aged 60 or above. Internal consistency was assessed using Cronbach's alpha coefficient and item-total correlations. Intraclass correlation/ ICC (3, K) was utilized to establish test-retest reliability. Results: MOEES-F has high overall internal consistency (α = 0.925). The internal consistency for both the physical (α = 0.927) and social (α = 0.950) subscales are high, while the self-evaluative subscale is adequate (α = 0.76). Item-total correlations are acceptable for clinical measures (0.520- 0.764). Test-retest reliability is excellent (ICC = 0.974, 95% CI [.949,.986]). Conclusion and Implications: The MOEES-F is a valid and reliable tool that healthcare professionals in the Philippines can use to design and deliver exercise interventions to older adults aligned with their outcome expectations. This can now be used as an outcome measure tool for prospective observational and experimental studies on exercise among older Filipino adults.
