Aim: This study aims to conduct translation, cross-cultural adaptation, and validation of the Oswestry Disability Index (ODI) into Ilocano since there is no existing valid and reliable standardized tool in Ilocano language that evaluates low back pain (LBP). Methods: The ODI was translated and cross-culturally adapted to the Ilocano language according to established guidelines of Beaton et al. 2000. Stages followed in the cross-cultural adaptation include forward translation, translation synthesis, back translation, expert committee review, and test of the pre-nal version. Responses were compared to determine the concurrent validity internal consistency of ODI then test-retest validation a week later. Forty-six (46) subjects (25 female and 21 male) with a mean average age of 46.65±17.98 years old with low back pain were recruited to answer the original and Ilocano ODI.Results: The ODI-Ilocano displayed a high degree of internal consistency, with a Cronbach's alpha of 0.93. The test-retest reliability was high (n = 45) with an ICC of 0.87 (95% CI, 0.74 to 0.98). The ODI-Ilocano version scores exhibited a strong correlation to the ODI- English version (Cronbach's alpha of 0.97, ICC 0.937, p-value ≤0.001).Conclusion and Implications: The Ilocano version of the ODI Questionnaire is a valid and reliable tool that can be used to measure self-reported outcomes of pain and disability in Ilocano-speaking participants with low back pain.
