OBJECTIVES: To develop a cross-cultural adaptation of the Arthritis Impact Measurement Scales 2-Short Form (AIMS2-SF) for Filipino patients with osteoarthritis and to determine the reliability and validity of this Filipino version. Design: Two-phase cross-sectional.


METHODS: I. Development of the AIMS2-SF Filipino version: forward/backward translation, committee review, and pretesting. II. Reliability and validity testing.


RESULTS: The cross-cultural adaptation of the AIMS2-SF, "Pagsukat sa Kalagayan ng Pasyente na may Arthritis," has a 5-domain structure (physical / function, pain / symptom, affect, social, role / work) with 26 items. Cronbach alpha is good in all scales (0.65- 0.77) except the social scale (0.40). The tool covers relevant domains and the items adequately cover each domain. Pearson's correlation coefficients are significant for 8 out of the 10 a priori hypotheses indicating convergent validity. Factor analysis identifies the five major factors corresponding to the scales of the tool reflecting construct validity. The items on the physical scale load on two separate factors suggesting that upper body activities should be distinguished from lower body activities.


CONCLUSION: The tool, "Pagsukat sa Kalagayan ng Pasyente na may Arthritis," is a cross-cultural adaptation of the AIMS2-SF that has a 5-component structure (physical / function, pain / symptom, affect, social, role / work) with 26 items. It is a reliable and valid tool for assessing health status in Filipino patients with osteoarthritis. (Author)
